Interesting. Did you notice any slowdown? In my experience, even if the crash
doesn't happen for a long time, a significant slowdown is almost immediate.

Here is some more info on how to reproduce our crash.
1. Compile the attached osgterrain program by overwriting
examples/osgterrain/osgterrain.cpp and recompile.
2. Run the program with
http://www.openscenegraph.org/data/earth_bayarea/earth.ive as input.
3. Wait (no further input is necessary). However, camera movement (tile
loading) produces earlier crashes. The attached image shows performance
of a typical run (without user input) where the frame time cyclically
increases until the program crashes.

Ola
ps. The output from the program is: iteration sample_ratio frame_time

return 0;
When run (tested on ive earth models generated with osgdem) the frame
time slowly increases, and, after a while, it warns about deleting a
still referenced object and then (after arbitrary time) crashes with a
glibc error.
Is this usage (setLODScale + setSampleRatio) safe? If not how should
these functions be called?
If it's a bug, we would be _very_ happy to have it fixed or pointers
about where to look in the code. We've previously submitted a patch
that switched to a ReentrantMutex in osgTerrain/Terrain.cpp (changeset

My system is running Centos 6.3 (x86_64) and I compiled osg in debug
mode with gcc 4.4.6. I have tested both against the 3.0.1 tag and
trunk (r13106).

Hi, I forgot to mention my interest in this: While I don't change the sample ratio in our application, I do rebuild the tile meshes in a similar way when the user changes the elevation data being used on the fly.

Hi, Sorry it has taken so long to respond. The joy of releases! The issue was resolved by updating to the 300 series drivers (had to use a modified inf file to be able to install drivers more recent than 276 for my laptop, that is why I didn't try this straight away.)

I personally investigated and reported another issue with VBOs on Nvidia drivers few months ago. And that issue was fixed in 290 driver series. It may be a long shot but I am just curious if these two problems could be related. While investigating my issue (http://forum.openscenegraph.org/viewtopic.php?t=9258postdays=0postorder=ascstart=0). I got following post from Ruben Smelik: [..] This mail reminded me of an issue I had a couple of years ago with VBO's on a particular Windows pc with a 9800GX2. I thought it was an issue of that PC, as it was quite unstable, so I didn't report the problem at that time. The solution I accidently found back then was to turn off Threaded Optimization in the NVidia Control Panel (Auto per default). But now I'm getting the bad result of your test on a GTX 480 (266.58 driver), and that fix works again. After turning off Threaded Optimization, I see the proper gradient displayed. Could you try this as well? [..] Your drivers are 276.21 so pretty close to 266.58 Ruben used. So I am now also curious if you could try to turn off Threaded Optimization and/or try newer drivers and see if the problem still exsists.

For anyone else who stumbles across this issue, my work around is to disable VBOs in silverlining. If I did this by using the SILVERLINING_NO_VBO environment variable it crashed so I simply hard coded them to off in SilverLiningOpenGL.cpp. I narrowed down the source of the issue to calls to AllocateVertBuffer in the same file.

In the earlier thread, it was noted that changing the threading model seemed to ;reset' the frame rate. I looked into this some more and it seems the behaviour is 'reset' when the draw thread is recreated started. If you return back to a thread that had previously 'decayed', it continues to decay from where it left off. e.g. singlthreaded decays to 50fps switch to draw thread per context and frame rate goes back to 100fps when a new thread is created and it starts decaying again switch back to single threaded (no new threads are created) and you are back at 50 fps and still decaying switch to draw thread per context and frame rate goes back to 100fps when a new thread is created and it starts decaying again It seems that a delay is being added to the current GL thread by silverlining. What ever it is doing, it is not making extra gl calls etc. Any ideas what could cause this sort of behaviour? I don't!

Each type of SilverLining Cloud entities has its own specific parameters and can be drawn with different algorithm and use differen graphics resources. So it may be important to know what SilverLining resourses are in use. Probably the best would be if you could send the sample source you are testing. Cheers, Wojtek Lewandowski 2012/3/16 Christiansen, Brad brad.christian...@thalesgroup.com.aumailto:brad.christian...@thalesgroup.com.au Hi, Thanks for the response. I have a little more details of the problem but am still completely stumped. This is my test: Start my application and leave it running for a while. Frame rate, memory use etc all stable. Enable silverlinng. As reported by gDebugger, after the initial expected increase, the number of reported OpenGL calls, vertices, texture objects (and every other counter they have) stays completely stable expect for the frame rate which reduces at a steady rate, a few frames each second. In the earlier thread, it was noted that changing the threading model seemed to ;reset' the frame rate. I looked into this some more and it seems the behaviour is 'reset' when the draw thread is recreated started. If you return back to a thread that had previously 'decayed', it continues to decay from where it left off. e.g. singlthreaded decays to 50fps switch to draw thread per context and frame rate goes back to 100fps when a new thread is created and it starts decaying again switch back to single threaded (no new threads are created) and you are back at 50 fps and still decaying switch to draw thread per context and frame rate goes back to 100fps when a new thread is created and it starts decaying again It seems that a delay is being added to the current GL thread by silverlining. What ever it is doing, it is not making extra gl calls etc. Any ideas what could cause this sort of behaviour? I don't!

Hi, I was the creator of the 3rd party dependancies package you downloaded (I should add that info to the wiki). When I started using VS2010 with OSG no binaries where available for the 3rd party libraries so I had to build them all myself. After doing so I made them available for others to ease the transition for others. The build is based on the VS9 binaries provided by OSG Visual.

We see very similar things with the nvidia driver in flightgear. In the end it turns out to be the mipmapping code in the nvidia driver. They seem to have a horrible slow implementation of that in their code. People report that if you provide precomputed mipmaps in your dds files, compressed or uncompressed, you do not see any hangs of the rendering code. As far as I can tell you can put the mipmaps also into the dds files by your mentioned nvidia tool. Also not exactly all nvidia chips seem to suffer from that problem. But a wide range works really bad. For osg I think one reliable way to get around that problem would be to precompute the mipmaps on the cpu in the database pager thread. This seems ugly, since the hardware could in theory compute that way faster than we can on the cpu. But the nvidia driver behaves that unpredictible in that area that I consider doing that for flightgear in a image read callback. The open source driver stack really shows how fast computing mipmaps could be using the hardware. The internal implementation sets up an fbo for the texture, sets up a rendertarget of the next higher mipmap level, and draws a quad textured with the current mipmap level into this render target. This is repeated until you have reached the last level. Even if the official open source driver cannot support 3ds compression for patent reasons, you can trick the sourcecode for the amd chips to at least show that this method also performs equally fast for compressed textures. I have not tried the nvidia ones, but I assume that they also have on chip 3ds compression and decompression and could behave the same. And no, I have no clue why this described algorithm is probalby not used for in nvidias binary blob.

Re: [osg-users] osgTerrain::getTile returns nothing
Hi,
Terrain tiles register themselves with the terrain during one of the scene
travesals. I cant remember off the top of my head if it occurs during the
update or cull traversal, but I think it might be the update traversal. If the
scene has not been traversed, the none of the tiles will have been regstered
yet.
Have a look at the traverse method of TerrainTile, I think that is where the
registration is done.
If you are using a VPB built terrain, all the tiles (except the tiles at level
0 ) are pagged in via the database pager. If the terrain hasn't been rendered,
then no tiles would have been loaded.
Cheers,
Brad

Subject: [osg-users] osgTerrain::getTile returns nothing
Hi,
I want to access TerrainTiles, but I get always a 0 Pointer.
Code:
ref_ptrNode model=osgDB::readNodeFile(Filename.toStdString());
//try to convert the node to an osg::Terrain and analyse it
ref_ptrosgTerrain::Terrain Terrain(model-asTerrain());
if(Terrain)
{
cout We have a terrain :)\n ...analyzing endl;
osgTerrain::TerrainTile *Tile=Terrain-getTile(osgTerrain::TileID(0, 0, 0));
cout Tile adress: Tile endl;
//get more detailed info:
osgTerrain::TerrainTest*
T=reinterpret_castosgTerrain::TerrainTest*(*Terrain);
cout TestTerrain Size: T-_terrainTileMap.size() endl;
}
The first thing that I checked is, whether my Node is an actual Terrain (which
it is, as Terrain is not 0).
Then I'm trying to access a random tile, I supposed that 0,0,0 should always
exist. But I get a 0-Pointer.
I can't access the TileMap from Terrain directly, so I copied the class
declaration, made the members public and cast the pointer. (the debugger
wouldn't show me any contents of _terrainTileMap.
But the map seams to be empty, size is 0. The documentation of Terrain is very
short, so I don't see any way to access the tiles, or in other words, there
seam to be no Tiles at all.
Thank you!
Cheers,
Jonathan

[osg-users] Independent update/cull traversals for different parts of a scene
Hi, I am trying to improve the consistency between the rendering of our terrain and the objects that interact with it. What I want to achieve each frame is the following (NB: all objects are under a single camera): 1) Do the update then cull traversal on the terrain. - Doing this first allows the rest of the scene to know exactly what terrain tiles will be used to render the frame. From this I can determine which areas of the terrain have been changed since the last frame so I can limit the intersections I need to do to keep objects on its surface. 2) Do some processing external to the OSG frame loop - At this stage our application will need to process various functions based on underlying terrain that are not directly integrated with OSG. 3) Do the update and cull traversals on the rest of the scene. - The big change in this passes is that during the update traversal the terrain tiles to be rendered is known. This ensure there is no 'frame lag' when placing objects a consistent distance on or above the surface of the terrain. 4) Render the combined result. At the moment I simply call frame on a Viewer instance. My first thought was to use node masks at the top of the terrain and 'the rest of the scene' and simply run the update and cull traversals twice each frame with a different mask. This seems easy to implement for the update traversals but I cannot see how I can easily implement this for the cull traversals as both the cull and rendering passes are implemented by the single ViewerBase::renderingTraversals. Overriding this function to add the functionality I want seems like a rather complex problem to tackle. Is there another, easier way, to get the results I want?

I came across this issue when I coded my own archive format.
I fixed the issue at the oter end and returned a FILE_NOT_HANDLED from my

Like you am I left wondering if this quick fix is a complete solution
so will need to think some more about the topic before commit a fix.
I have done some testing and some thinking about the issue and feel
that the fix you suggested is a good solution, the code I've checked
into svn/trunk is essential the same, only adds a little text in
explanation:
// check loaded archives.
AvailableArchiveIterator aaitr(_archiveCache, _archiveCacheMutex);
for(;aaitr.valid();++aaitr)

ReaderWriter::ReadResult rr = readFunctor.doRead(*aaitr);
if (readFunctor.isValid(rr)) return rr;

// don't pass on FILE_NOT_FOUND results as we don't want
to prevent non archive plugins that haven't been

if (rr.status()!=ReaderWriter::ReadResult::FILE_NOT_FOUND)
results.push_back(rr);

Re: [osg-users] Migration of website and version control
Hi, I thinking moving to git would be a very positive move. I haven't used it a great deal but I am very familiar which mercurial which is similar. I have also recently been involved in migrating a fairly large project from SVN to mercurial so I might be able to contribute something on the technical side of any move. For the wiki, I quite like Confluence (http://www.atlassian.com/software/confluence/overview ). I have used it for many years and it is simple, powerful and works well. It is a commercial product but they licence it free to open source projects (http://www.atlassian.com/software/views/open-source-license-request ).

One of the reasons that adds a little imperative to the move is that the current hosts of our server AI2, Universidad Politecnica de Valencia, Spain, look unlikely to be able to continue providing due to funding cuts. Technology wise it would also be good to find a better wiki and version control system. We also need engineers to help out with migration and ongoing maintenance of new servers and services that will be moving too. There is a wide range of different hosts and technologies we could use, and I'm happy to admit that I'm no expect in hosting, webserves, wiki management, version control systems, but this is a huge community so no doubt there is lots opinions, and perhaps even a few experts out there that might be able to help out with great suggestions and time to make things happen. To help kick things off. On the hosting side I currently have a Dreamhost account that provides the mailing lists services that we currently use, and my account looks to be sufficient for provide a Tracs and Subversion services as well - so pontentially we could move to Dreamhost and rely upon them for management of the server and server software and let us concentrate on the content. I really don't know how well this would work out having not tried to migrate services other than mailman across to them. If we do have to move existing services across quickly this might be strong contender. Technology wise I am comfortable with Subversion, but for fully distributed it's not as powerful as newer technologies like git. We've discussed both Mercurial and git on the mailing list before as possible contenders and feedback I've got from various experiments out in the community is that git looks to be most practical for our needs. Rather spend lots of time discussing the pros and cons of these two technologies I'm happy to narrow things down to migrating to git. What is open for discussion is really when and how we migrate to git. One possibility with migrating to git would be to have our own server, use a host like Dreamhost or go with another 3rd party like github. For the latter there is already a mirror of our subversion repository hosted over at github maintained by members of the community (please come forward as I've forgotten who set it up :-) : https://github.com/openscenegraph/osg I haven't used git too much yet other than to check out third party libs, but when the time comes I'll just have to roll my sleeves and dive and learn to use it properly. github also now have their own wiki, Gollum: https://github.com/features/projects/wikis I know nothing about Gollum so can't comment on it, I'm not overly impressed by Tracs - it's been sufficient but not that that powerful, so I'm reluctant to go with yet another dev wiki that is almost by not quite as powerful as the likes of MediaWiki. I have to admit that I really don't know too much about the practical behind the scenes management of MediaWiki let alone Gollum and Tracs so I really need to feedback from the community of the various strengths, weaknesses and practicalities. Finally once we've decided upon hosts for our needs, and the technologies that we migrate too we'll need to do the migration of our present wiki and version control systems. We'll need the engineers to help our with coordinating and undertaking this work. Once we've got a basic plan and the people in place we start migrating bit by bit. I look forward to your thoughts and in particular your offers of assistance ;-) Cheers, Robert.
[osg-users] Bug in NVTT image processor.. no sure about the solution
Hi,
I have discovered that the NVTT image processor contains a bug which results in
a crash is an already compressed image is passed in (I know you shouldn't do
this anyway).
The problem lines are:
if (image.getPixelFormat() == GL_RGB)
{
convertRGBToBGRA( imageData, image.data() );
}
else
{
convertRGBAToBGRA( imageData, image.data() );
}
This assumes that if the format is not GL_RGB, it is always GL_RGBA, and thus
there are 4 * s * t values in image.data().
To fix the issue I could simply make the else and else if(GL_RGBA) { ... }
else return false, but I am concerned that this may result in a failure to
compress other formats which are valid, but I am not aware of.
The other approach would be just to test the size of image.data() and make sure
it is big enough but that will just avoid a crash, not necessarily result in
correct behaviour.
Any input to what the correct approach should be?
Cheers,
Brad

I have posted a submission which adds a new function ( getCurrentTime ) to ImageStream and have implemented the new methon in the direct show plugin, and implemented it in ffmpeg by simply calling getReferenceTime.

Re: [osg-users] [vpb] Multiple maps in model with osgdem? (vpb)
Hi, The way the resolution works is thus (once again, this is just from memory, so no guarantees an accuracy): Level 0 will cover the entire bounds in a single texture (assuming you use the defaults, this will be 256x256 pixels). Level 1 will then split the terrain into two or more textures. The number of textures that are created depends on the aspect ratio of the source data. I think you will always end up with either one row or one column, with the required number of rows/columns to maintain the aspect ratio. For example, for a whole world database (twice as many lon values as lat), you will end up with one row, two columns (each tile is 180 degrees width and height). From this point, things get easier, as for each level, each texture is divided into four textures which cover the same region, a standard quad tree. To calculate the resolution of a level you simply divide the number of pixels by the covered area. As a simple example, lets say your source data covers a quarter of the world from 0-90 lat and 0-90 lon. At level 0, this is covered by 256x256 pixels, therefore the resolution is 90/256 degrees per pixel. At level 1, this is covered by 512x512 pixels, therefore the resolution is 90/512 degrees per pixel. At level 2, this is covered by 1024x1024 pixels, therefore the resolution is 90/1024 degrees per pixel. etc etc To calculate the resolution of your source imagery use something like gdalinfo to get the required details. I am sure everything is now as clear as mud for you : ) Cheers, Brad -Original Message- From: osg-users-boun...@lists.openscenegraph.org [mailto:osg-users-boun...@lists.openscenegraph.org] On Behalf Of Chris Ess Sent: Tuesday, 13 September 2011 5:49 AM To: osg-users@lists.openscenegraph.org Subject: Re: [osg-users] [vpb] Multiple maps in model with osgdem?

Re: [osg-users] [vpb] Multiple maps in model with osgdem? (vpb)
Hi, Some quick answers for you: . Any thoughts on how to specify textures at each of those levels? Can I specify each level with a different -t TextureDir argument? You use the '--levels' argument, one for each source. For example: --levels 0 5 -t GeoTiff1.tiff --levels 6 10 -t GeoTiff2.tiff --levels 11 15 -t GeoTiff3.tiff Also, is osgdem smart enough to figure out when the best time to show the next level is based on scale? In short, no. The longer answer is that all the infornation is actually available internally to osgdem but there is no mechanism exposed to use this info in the way you wish (unless this has chaanged since I last worked with the code) Cheers, Brad -Original Message- From: osg-users-boun...@lists.openscenegraph.org [mailto:osg-users-boun...@lists.openscenegraph.org] On Behalf Of Chris Ess Sent: Friday, 9 September 2011 9:43 PM To: osg-users@lists.openscenegraph.org Subject: Re: [osg-users] [vpb] Multiple maps in model with osgdem?

This is actually very exciting news, as I was getting ready to redesign some software I have been working on to try to force the same effect (and the deadline is in less than a week!). Now, I will have to ask that you excuse my ignorance, but I am very unfamiliar with the vpb tool and mapping tools in general to be honest. The application I am using requires that I use VPB/osgdem 0.9.10 since we are using a third party library that runs on top of an older version of openscenegraph to display the maps. The command that I have been using to generate maps from the GEOTIFF textures I have is something like the following: Code: osgdem -o MyMap.ive -l 15 --compressed --skirt-ratio 0.0 --levels 0 15 -t MyGeotiffTextureDir I have looked up the command line options on the Osgdem/vpbmaster Command Line Options page I noticed there is a list /w a small description but it didn't seem very helpful unless you already have some experience with how the application works. I have geotiffs taken from a number of different scales (in separate directories) : 5M:1, 1M:1, 500K:1, 250K:1, 100K:1 ...etc I guess where I am getting confused is how I specify what scale of textures I want to show at what levels. Its my understanding that using the command above, I am currently generating 15 levels. Any thoughts on how to specify textures at each of those levels? Can I specify each level with a different -t TextureDir argument? Also, is osgdem smart enough to figure out when the best time to show the next level is based on scale? As far as the popping effect mentioned earlier, that isn't a concern. It may actually be better as our customers will be able to recognize when they are looking at different map data/scales.

Hi, What you want is possible with VPB by restricting the levels at which the maps are used. I cant remember the options off the top of my head, but you will need to specify each source individually and specify at what levels it should be used. From memory, the levels are quad tree levels so you may need to do some calculations of your own (or use trial and error) to figure out what level a certain map should become available.

(vpb) Hi, I am not sure if this is even possible, but I would like to use 5 or 6 different maps taken at varying altitudes but of the same region and create one model/map. As a user zooms in on the model/map the texture would update. For example: Say I had a map of North America, then a more detailed map of the United States, and finally another detailed map of just a state in the US. As the user zooms in they would see North America, then the United States, and finally a detailed state map. From the little bit of experimenting I have done, I have thrown all the geotiffs in one folder (from all 3 different maps) and built a model. What I am seeing is parts of the map are at the original scale (North America), then the regions of North America that have more detailed tiles available from the sub maps are simply overwritten with the more detailed tiles. So its like 3 different map formats all on one map and looks like some kind of Frankenstein monster. What I would like is for all of the North America map to display, then as the user zooms in, if a more detailed view/map is available, it should update accordingly, showing the detailed portions only if the user is at the necessary scale/zoom level.

[osg-users] Constantly increasing draw/gpu time
Hi, I have come across a difficult issue and have run out of ideas of where to look to try and find the solution. What I am observing is this: Leaving or application running, without ANY modification, results in a fairly rapid rise in both Draw and GPU time (as shown in on the stats hud). This results in a FPS drop from ~250fps down to ~30fps within 15 minutes. This drop seems to continue indefinitely, though the rate of slowing does seem to decrease. During this time both OSG's diagnostics and gDebuggers are showing a constant load on the card (same number of vertices, textures, VBOs etc) which is expected as the scene or viewport is not being modified. The memory and CPU use of the application does not change. The only thing that does seem to change is how long it takes to dispatch all the draw calls. I have reproduced this on a couple machines. I am using OSG 3.0, Windows 7 64 (my application is 32 bit though) and an Nvidia GTX 460M with driver revision 267.21. If anyone can suggest anything (at all) that I could look into it would be greatly appreciated as I am completely stuck.

Re: [osg-users] Setting the reference location for LOD calcs for a camera
Hi, I found what I was looking for, and it might even provide the easier solutin you are looking for. I change the reference frame from ABSOLUTE_RF to ABSOLUTE_RF_INHERIT_VIEWPOINT. Stepping through the code it appears that in this mode, the viewpoint is inherited from the parent camera. So, as long as your RTT camera is a a child of your main camera you should get the beaviour you want. From the testing I have done so far it appears to work as I have described. If anyone can confirm this is the intention of the setting that would be great.

Re: [osg-users] [vpb] Questions regarding setname, optional layers and layer inheritance
Hi, I haven't done a direct comparison on performance, but the only real overhead at tile loading is a small step in deciding which images to load. There are more files read from disk as the images are not inline which is probably a little slower that reading a single file but I don't think it will effect performance much. From my experience, the biggest hit is the 'unbounded' number of textures required to render a single tile. Using the standard approach only a single texture exists for each tile. Using optional layers you could theoretically have an unlimited number of textures to render to each tile. In theory you could even run out of texture units / samplers for each tile (though in practice you need a lot of optional layers for this). Accessing and blending multiple textures will obviously be slower than only using one, though I havent noticed much of a performance difference in practice when I turn on or off a bunch of optional layers. The other side effect of this is complicating the management of the shaders used to render the tile (assuming you are not using fixed function). To get good performance on both ATI and Nvidia cards I ended up creating a separate shader for all possible number of active optional layers and switching between them at run time. this works much better than my original approach which used dynamic branching in a single shader.

Hi, I also didn't have a lot of luck with external elevation layers, but didn't really need them so didn't look into it any further.

[osg-users] GLSL shadow2D / shadow2DProj question
Hi,
I am implementing some shadows at the moment and have come unstuck with my
understanding of how to sample a shadow texture.
To test my understanding, I implemented what I though shadow2D() would do using
'standard' sampling and a few calculations. This lead to the following code
which works as expected:
varying vec4 projShadow;
uniform sampler2D depthTex;
float val = texture2D(depthTex, projShadow.xy / projShadow.w).r;
float fragDepth = projShadow.z / projShadow.w;
if(val = fragDepth) {
col = mix(col, vec4(1,0,0,1), 0.3); //shadow
} else {
col = mix(col, vec4(0,1,0,1), 0.3); //lit
}
From my understanding I should be able to replace all this with:
varying vec4 projShadow;
uniform sampler2DShadow depthTex;
float val = shadow2D(depthTex, projShadow.xyz / projShadow.w).r;
or
float val = shadow2DProj(depthTex, projShadow).r;
When I do this I just get garbage.
Given I am getting the correct result with the first approach, and I think the
second should do exactly the same thing, I am stck as to why I cant get shadow
sampling to work correctly. Any suggestions would be greatly appreciated.
Cheers,
Brad

Re: [osg-users] [vpb] Questions regarding setname, optional layers and layer inheritance
Hi, Firstly a tip from building large databases myself, make sure you source imagery has been optimised as much as possible. I have found ecw files are much faster to process than other formats due to their exceptional speed in creating arbitrary overviews. If you are using GeoTiffs make sure you have created 'overviews' (I cant think of the correct name) for them (basically a set of mipmaps stored inline). This make a big difference to generation speed. I would also suggest you look pay attention to what output format you use for your imagery. I have found that compressing the output imagery takes the greatest amount of CPU time of the build process. If you use no compression, the output will be massive. I use these settings: --compressed-dxt1a (of dxt1 if my data completely covers the area being generated or I am using layer inheritance). --compression-quality-fastest (I honestly cant see a visible difference compared to the high quality mode, but runs almost an order of magnitude faster) --compressor-nvtt-nocuda (I run on a machine with no or poor graphics card) Now on to your question regarding options: --layer-inheritance [Lowest/Nearest/No] This comes in to play when the source data for a tile does not cover the full extents of the tile. This option determines what you see in the 'empty space'. When set to 'No', the empty space is left empty. If your output format doesn't include an alpha channel, the 'empty' space will be black, if your output format does support alpha, the empty space will be transparent. When 'Lowest' is specified, the lowest resolution data available for the area if used to fill the gaps. When Nearest is specified, the nearest resolution data available for the area if used to fill the gaps. Note that when you use optional layers, it really only makes sense to use 'No'. --set setname used by itself, I haven't been able to figure out what effect this has. --optional-set setname When used in conjunction with --set (i.e. specify both with the same value: --set MySet --optional-set MySet) you imagery layer is stored in an external (i.e. not in the .ive or .osgb file) directory structure. This allows a tile to be loaded without having to load all the optional images associated with it. --optional-image-layout [inline/external-set-dir/external-local-dir] --optional-elevation-layout [inline/external-set-dir/external-local-dir] This determines how optional layers will be written to disk. Using inline stores the optional layers within the .ive/.osgb file. These seems to defeat the purpose of optional layers but I am probably just missing the use case for this. From my experience both external-set-dir/external-local-dir produce the same output, but this may have changed since I last played with these options. I think the intention was that external-set-dir places files for each optional layer in a folder named after the set, while external-local-dir places all the optional layers in a single directory structure. This needs to be confirmed though. How does the idea of optional layers work? I assume it is possible to plug in optional layers for DEM and for textures independent? It is, though I haven't personally tried optional elevation data. Do I need a special terrain technique to use such a database with optional layers, or can I use the standard osgViewer? I have written my own terrain technique to control the display of optional layers (a sub-class of GeometryTechnique) but I think you can access up to three optional layers via a MultiTextureControl node used to decorate the generated scene though I haven't used this myself. I am pretty sure the default osgViewer doesn't provide access to this functionality though. You should also look at the osgTerrain::TerrainTile::setTileLoadedCallback() method and the default implementation WhiteListTileLoadedCallback which can be used to control the loading of optional layers (I have also implemented my own call-back). I will also add a couple of comments not directly related your questions: I would suggest you look closely at creating your own TerrainTechnique. Subclassing GeometryTechneque is pretty easy and will give you a lot more control. While this was quite a bit of work, I have managed to dynamically merge the output of multiple VPB databases at runtime. This provides a lot more flexibility to 'mix and match' different datasets and greatly simplifies the process of adding a bit of new data. As a side note, once you generate a large database moving it about is very painful due to the huge number of small files it creates. To help with this I place my databases into an archive format (I think the largest archive I have created is ~150gig), though this is probably not practical when your output will be several terabytes. If you decide to look into this, a couple of pointers / warnings: - you will need to convert the relative file names for optional layers into filenames relative

When I build VirtualPlanetBuilder with VS2010 I get errors complaining about

hand). The same code works without issue on non-windows platforms and all other
VS compilers tried.
As I don't have time to look into the issue I simply force the link to complete

Re: [osg-users] OT: VS2010 LNK2005 problem related to ostringstream
Ok, I have localized the problem.
For example, the class osgDB::fstream:
class OSGDB_EXPORT fstream : public std::fstream
{
};
which just inherits from std:.fstream causes the symbols of std::fstream to be
exposed into osgDB.dll
This effectively means that It might cause problems for people linking against
osgDB.dll later on.
Same goes for inheriting from std::string, std::ostringstream etc.
This must obviously be a bug, a very serious one in VS2010.
We had a class derived from std::ostringstream, which exposed the symbols in
the vtable for the class:
namespace ns
{
class Notify : public std::ostringstream
{
};
}
Using depends.exe to analyze the dll-file gives:
const ns::Notify::`vftable'{for `std::basic_ostringstreamchar,struct
std::char_traitschar,class std::allocatorchar '}
My issue was reported to the msdn forum. Their first take was: Oh you use
CMake, thats not our product :-)
But in later threads, they tried to reproduce the problem without luck...
So if you manage to reproduce this in a small example, go ahead and post it. We
must make them aware of this problem.

Hi all,
I just found a fix after some tests, but it is not a fix I am proud of.
I just added the close() method in osgDB/fstream implementation, so there is no
conflict because my fstream implementation uses osgDB/fstream and not
osgDB/fstream AND std::fstream.
I will continue to investigate to be sure to understand why this occurs, but
any advices or explanations are welcome.
If my fix is accepted this could be a submission for OSG, eventually...
Thanks.
Regards,
Vincent.

Hi Mourad
Thanks for your answer but I already checked that. TsLib_MDdNET2010 is a static

Re: [osg-users] Download details: Microsoft Visual Studio 2010 Service Pack 1 (Installer)
Hi, I seem to be the only one who actually much prefers 2010 to 2008. I agree it is slower at times but I find intellisense to be more useful / accurate than in 2008. Maybe this is because (other than OSG) the C++ projects I work on are pretty small. The major issue I have is the need to force the linking of VPB due to the multiply defined symbols. I haven't seem any issues, but I really don't like to use hacks like this. Does anyone know if SP1 fixes this issue?

Re: [osg-users] multiple tex gen modes in a single scene
Hi, I have a small amount of extra info to add, which confuses me even more. Revisting all my code I discovered that my overlays actualy use two eye linear tex gens (one for close items, one for distant ones, a bit like the parralel split shadow maps) with different matrices and different units. These work fine in isolation, but don't work when I add in the third shadow tex gen. The code that adds the tex gens to the positional state container is almost identical. I am now very confused as to why I can use two tex gens for my overlays but it wont work with shadows added.

All positional state has to be positioned by a positional state node, and for glTexGen this is TexGenNode. During the cull traversal the OSG collects the positional state and binds the TexGen/Light/ClipPlane to modelview matrix at that point in traversal, this binding is done via the PositionalStateContainer, and there is one of these per RenderStage. During the draw traversal the positional state is then applied prior to the traversal of the RenderStage, and fixes each positional state in the appropriate place. While this technique doesn't properly fix the state as required, it does limit you to one position, per stage, you can't have two eye line tex gens/lights/clip planes applied on two separate subgraphs. Object linear TexGen isn't positional state so can be applied in the normal way and you have multiple of these per stage without problem. To have multiple Eye linear TexGen/TexGenNode's you'll need to break the scene up into multiple RenderStage and use the clear mask set to 0 on the subsequent stages so that each stage overlays correctly on the previous one.

Re: [osg-users] Limitation in current ImageLayer serializer
Hi,
I have found the problem that is causing me trouble. The code I posted is
writing two 'end brackets':
os osgDB::BEGIN_BRACKET std::endl;
os.writeImage( value );
os osgDB::END_BRACKET;
If I don't write the an end bracket explicity then everything seems to work ok.
I am guessing that the writeImage call is adding the end bracket for me. Is
this expected behaviour? The code looks incorrect without it:
os osgDB::BEGIN_BRACKET std::endl;
os.writeImage( value );
Cheers,
Brad

Hi,
I have found a little more time to work on this issue but have become stuck.
Using a user serializer I have managed to read and write the image sucsessfully
in the case that the image is loaded, but cant get it to work in the case the
image should not be loaded. I think the issue is that, when I don't want want
to read the image (i.e. deffered loading is enabled), then I still need to read
the image 'header' from the stream. If the image is embedded in the file then I
think I will need to read the entire image regardless of wether deffered
loading is enabled or not (I haven't looked at this case yet).
The code I am using is (I am testing with .osgt files so far):
static bool readImage( osgDB::InputStream is, osgTerrain::ImageLayer im )
{
std::string filename = im.getFileName();
if (!filename.empty())
{
bool hasImage;
is hasImage;
if(hasImage) {
is osgDB::BEGIN_BRACKET;
bool deferExternalLayerLoading =
osgTerrain::TerrainTile::getTileLoadedCallback().valid() ?
osgTerrain::TerrainTile::getTileLoadedCallback()-deferExternalLayerLoading() :
false;
if (!deferExternalLayerLoading)
{
osg::ref_ptrosg::Image image = is.readImage();
if (image.valid())
{
im.setImage(image.get());
}
} else {
//I think this is where I need to read of the image 'header'
}
is osgDB::END_BRACKET;
}
}
return true;
}
static bool writeImage( osgDB::OutputStream os, const osgTerrain::ImageLayer
im )
{
const osg::Image* value = im.getImage();
bool hasObject = (value!=NULL);
os hasObject;
if ( hasObject )
{
os osgDB::BEGIN_BRACKET std::endl;
os.writeImage( value );
os osgDB::END_BRACKET;
}
return true;
}
The relevenat section of the osgt file that is created is:
Layers 1 {
Object osgTerrain::ImageLayer {
UniqueID 9
Name kljhjkl
FileName earth_L1_X0_Y0_kljhjkl.dds
Locator TRUE {

UniqueID 4
}
}
Image TRUE {
UniqueID 10
FileName earth_L1_X0_Y0_kljhjkl.dds

}}
}
And the error I get when loading the file with deffered loading enabled is a
bad allocation error.
Any suggestions would be greatly appreciated!

much attention to the special mechanism that may be required when

And write/read images and activate them by ourselves. Here we can read

Re: [osg-users] [3rdparty] FWTools on Visual Studio 2010?
Hi, I don't know of any FWTools binaries that have been built with 2010 but you can get proj (and quite a few other useful libs) by downloading the GDAL developer binaries found here: http://vbkto.dyndns.org/sdk/ I am the fool responsible for most of the 2010 OSG binaries and I must say this is the last time I will be using a new version of VS soon after release. It is a real pain building 3rd party libraries with 2010 as most don't yet support it so you are on your own. Good luck!

[osg-users] Pausing the database pager
Hi, I am currently implementing run-time merging of datasets created using VPB. When I add a new dataset I walk through an existing PagedLOD structure and add the appropriate Layers to the existing terrain tiles. During this process I may also update/add children and or settings of an existing PagedLOD. The same class that manages this process is also responsible for loading subtiles in response to a database request. The problem I am having at the moment is that it is possible for my update thread (the frame loop is paused for the update) to be in the middle of merging in a new data set when a request comes in to load subtiles. This is causing some headaches as it is possible for me to miss updating subtiles that have been created due the request, but not yet added as a child to my PagedLOD. I am also iterating through a vector in one of the threads and updating it in the other which is obviously bad news. I could implement some sort of locking mechanism to solve the problem but I think it would be much cleaner to, before starting the update, pause the DatabasePager, clear any outstanding requests and wait for any requests that are currently being processed to complete. I could then safely updated the PagedLOD structure, then restart the pager. There is a setDatabasePagerThreadPause method but from my understaning of the code this returns immiadiatley. What I need to do is wait for the the pause to be completed before I continue. Is this functionality already available? I cant see how to achieve what I want but the pager is a not a simple class to understand so I may be missing something.

Re: [osg-users] Proposed changes to VPB re compression

There is a big difference between the two video cards but both are much faster than the CPU. I was a bit disappointed at the CUDA results especially given this will only work on Nvidia cards and some formats (the DXT1a cuda score isn't given as this output format doesn't support cuda acceleration atm). Before these tests I was leaning towards defaulting to using NVTT for maximum compatibility but this doesn't look so good now.

Re: [osg-users] Proposed changes to VPB re compression
Hi,
I remembered you had previous mentioned about the debug build of nvtt so I did
check that. I was also having some issues with building from source and using
static libs for nvtt so I ended up switching to the pre-build binaries from the
Nvidia web site just to be sure I wasn't breaking something at my end. Using
either my own release build or the pre-built binaries the results were the same
(as I posted before).
I have now completed the changes need to be able to switch at runtime between
the different techniques and have done a quick test of vpbmaster generating 6
levels of blue marble data from an ecw file. In this test the run using the GL
compressor finished in 17.7 seconds while the nvtt run took 90 seconds. I
wonder if this could be a platform difference? Maybe the GL drivers under Linux
do the compression in software while the windows ones do it in hardware.
Regarding submitting these changes, I have had a quick look at what
modifications I have made and while they aren't huge, they have been made on
top of the various outstanding submissions for VPB. Would you prefer me to hold
off with this submission until you have gone through the others individually (I
will handle and merges on my end) or should I just submit the combination of my
and Fabiens changes as I have them?
I have named the options:
--compressor-nvtt (nvvt, cuda if available) --compressor-nvtt-nocuda (force no
cuda) --compressor-gl-driver (current method)
which match to new build option 'compressionMethod':
enum CompressionMethod{ GL_DRIVER, NVTT,NVTT_NOCUDA }
Let me know if you can think of better names.
Cheers,
Brad

Hi Brad,
When I first tested the NVTT based compression on my Linux system I
found that the NVTT compression was slower than GL based. I then
checked the build options of NVTT and the Release build was set,
fixing this and then a rebuilding NVTT improved the results so they
matched the GL compile time.
As for the idea of having the -texture-process command line option to
select which to use, I think this is a good idea. #if'defing the code
paths for when NVTT isn't available is a perfectly acceptable thing to
do in this instance as we aren't talking about lots of place in the
code.

[osg-users] Tip for large VPB builds
Hi, Over the weekend I discovered some data preparation steps that have resulted in a dramatic improvement in the performance of my VPB generation runs and thought I should share. While I haven't done a proper benchmark, it appears that the changes I made to the source data have cut the processing time for one of my datasets from around 18 days to just 1.5 days. The original source data was several thousand DTED tiles, 12 large GeoTiffs (about 1 gig each) and hundreds of small GeoTiffs (10s-100s of megs each). Before sending the data to VPB, I used Global Mapper (not free but it is cheap for what you get) to convert all the color data into one ecw file per layer (3 total). I also converted the DTED tiles into a single compressed .img (edras) file and generated overviews in this file using GDAL. I tried creating a JPEG2000 elevation file but this crashed on each attempt. After this, the source data went from 1000s of files to just 4 and the size on disk was reduced by roughly one order of magnitude. All this processing took (a vague guess of) 24 hours. Given that the VPB process has been reduced by many times this it appears to be a relatively small overhead and makes the data a lot easier to deal with. I think the main improvements in speed come from ECWs brilliant performance in generating arbitrary overviews of the color data as well as a clear savings in disk overhead. The only downside with using the ecw format is the slightly painful liscing of the ECW sdk which meant that I had to rebuild GDAL with ECW support rather than using the gdal binaries available from the 3rdParty libs on the OSG wiki. It is however possible to download pre-built gdal binaries (which you can link OSG against) with ecw support, though I am not convinced they meet the license requirements of ECW. If anyone else gives this a shot I would be very interested to see if the gains I have found can be repeated.

[osg-users] Proposed changes to VPB re compression
Hi, I have found some time to work on the new NVTT compression path in VPB and have a couple of quick questions about how best to proceed. My current plan is to add a couple of new options to osgdem/vpbmaster such as --textureProcessor-GL (old implementation) --textureProcessor-CPU (current nvtt implementation) --textureProcessor-CUDA (nvtt with cuda). When osgdem is run, it will try and use the requested texture processing path, failing back to CPU if this is not available. Does this approach sound reasonable? In relation to this, should the use of nvtt remain optional? This does seem doable but it will result in some macro uglyness in the code and will complicate some sections. One last question for anyone who has built VPB with the new nvvt code, did everything build ok after cmake had configured the projects? I found I had to add nvtts internal squish.lib as a dependancy to get things building. I have added this to the cmake setup (as well as the cuda runtime (optionaly)), but am curious to know if this requirement is purely an artifact of how I built nvtt. One final note, if anyone wants to have a quick play with the new code under windows I have packaged up the reuqired 3rd party libs (gdal, nvtt, cuda) for VS2008 x64 and x86 and can post them if wanted.

Ok, I have localized the problem.
For example, the class osgDB::fstream:
class OSGDB_EXPORT fstream : public std::fstream
{
};
which just inherits from std:.fstream causes the symbols of
std::fstream to be exposed into osgDB.dll
This effectively means that It might cause problems for people linking
against osgDB.dll later on.
Same goes for inheriting from std::string, std::ostringstream etc.
This must obviously be a bug, a very serious one in VS2010.
We had a class derived from std::ostringstream, which exposed the
symbols in the vtable for the class:
namespace ns
{
class Notify : public std::ostringstream
{
};
}
Using depends.exe to analyze the dll-file gives:
const ns::Notify::`vftable'{for `std::basic_ostringstreamchar,struct
std::char_traitschar,class std::allocatorchar '}
My issue was reported to the msdn forum. Their first take was: Oh you
use CMake, thats not our product :-)
But in later threads, they tried to reproduce the problem without
luck...
So if you manage to reproduce this in a small example, go ahead and
post it. We must make them aware of this problem.

Hi,
Unfortunately I can't offer a solution, but I thought I would mention
I have come across this exact problem and have also pulled my hair out
trying to find a solution. This same problem exists when building
virtual planet builder, linking with osgDB causes the multiply defined
symbols. I had no other issues building the 3rd party libs and osg
with 2010.
The only way I could move forward was to allow multiply defined
symbols (as has already been mentioned). I agree this seems dangerous
and is not a solution but it has allowed me to continue working. So
far it hasn’t caused any issues with my vpb build.
Given you have used the streams extensively without issue and it seems
osgDB is the source of the trouble, have you had a look to see if
there is any discernable difference between your code and that in
osgDB ?
I would love to find a solution to this.
Cheers,

Subject: Re: [osg-users] OT: VS2010 LNK2005 problem related to
ostringstream
I have verified the build mode for all ingoing libraries.
I build all the dependencies myself. Including OSG.
The problem I have (which is OSG related), is that if I build without
OSG support (no rendering), it all works.
And I still use std::ostringstream and std::stringstream quite
extensively...
We still link against OpenThreads (but no rendering).
So only when I link against osg (osg.lib, osgDB.lib, osgText.lib,
osgShadow.lib, osgViewer.lib osgGA.lib) I get this problem.
I have verified that osg (and OpenThreads) are all built consistently
all over the field. Release and /MD (MultiThreadedDLL), which is
default from CMake.
So I can use/link against OpenThreads.lib, but not OSG...
Rather nasty problem, I'm trying to reduce it, but I'm getting
nowhere.
And once again, same settings, same CMake version, same code all over
the place, and it works in VS2008...

For my projects I include a vc version number in the name, so

Re: [osg-users] Intersecting volumes and terrain
Hi, I haven't done this myself, but I believe the PolytopeIntersector will give you a list of points you are after. You need to define the planes that make up your volume and then use an IntersectionVisitor with the PolytopeIntersector to intersect agains your terrain. From there you can retrieve the intersection points. I know something similar is done in the osgSim::OverlayNode though I think its usage is more complex than yours.

Re: [osg-users] [osg-submissions] Crash with SVN version of Tessellator (FIXED)
Hi Robert, I have done some more reading and I understand a little what is going on. With this understanding I have made the same fix but without defining any additional macros (though I do use the already defined GL_APIENTRY). The change to tess.h also removes the special case for windows as this is handled already by using the existing GL_APIENTRY. The cause of the problem is the fact the OSG is built using the _cdecl calling convention (which is normal). However if you're using any callback functions with the Windows API (which the GLU implementation does), they must be declared using CALLBACK and/or WINAPI. That will apply appropriate decorations to make the compiler generate code that cleans the stack correctly. On Windows with visual sutio GL_APIENTRY ends up being defined as WINAPI. Let me know if you are happy with the new approach.

[osg-users] Crash with SVN version of Tessellator

The previous (working) version of OSG I used was revision 11703 and the new (broken) revision is 11835. I know al the new GLU code has been added between these revision so I am guessing that is what is causing the error. Before I go much further I was wondering if anyone had any info that might help me track down the issue. It doesn't seem that the required usage of Tessellator has changed but I am hoping it has so I can simply call some different methods to fix the issue.

Java programmer after all : )
I assume this is a platform specific issue of some type? It would be great to
get some feedback from others using different platforms and compilers to try
and narrow down the cause of the crash.

Hi Brad,
As you've spotted the GLU tessellation code has now been integrated
with the build of the core OSG library. I have taken the code from
Mesa 7.9, which in turn based it's GLU implementation on SGI base.
I'd expect most GLU implementations are based on the original SGI code
base, they might all have different bug fixes applied to them, perhaps
the Mesa code doesn't have a fix that the previous GLU library that
you were linking against had, or perhaps I've introduced a bug during
integration.
One advantage now is that you will be able build the GLU code with
debug along with the rest of the OSG and be able step through it see
where problems might be arising. From your stack trace the line:
:push_back(osg::Vec3f * const _Val=0x)
Looks pretty suspicious. The debug info doesn't really reveal exactly
which code is calling phs_back with the dodgy value.
BTW, Do you see problems when you run osgtext3D? Or osgtessellate?
Both of these will be using the newly integrated GLU tessellation
code.
Robert.

Subject: [osg-users] Crash with SVN version of Tessellator
Hi,
I have just updated to the latest revision of OSG and am now getting a crash
when calling Tessellator.retessellatePolygons.
The code in my application calling this function hasn't changed in many years
and has started breaking since the update. I have debugged the issue a little
and the crash is occuring when the Tessellator::endTessellation function is
called. The crash occurs on a call to free. I think I will need to do a full
debug build of OSG to get much further with my debuging (I am using release
with debug info) but a full rebuild will take me a while.
The previous (working) version of OSG I used was revision 11703 and the new
(broken) revision is 11835.
I know al the new GLU code has been added between these revision so I am
guessing that is what is causing the error. Before I go much further I was
wondering if anyone had any info that might help me track down
Re: [osg-users] Crash with SVN version of Tessellator (FIXED)
Hi,
I have managed to track down the issue and have attached the fix. The problem
was that the GLU functions were using a different calling convention. I don't
for a second pretend to understand the issue properly or why it exists as
anything that combines windows and C++ completely defies my understanding.
However, what I have done seems reasonable and does fix the problem. Somebody
who actually understands this stuff might have a cleaner solution but the
changes are actually very small and seem inline with what has been done in
other parts of OSG.
For anyone who is interested or might understand the errors better, the Visual
Studio debugger reported the following:
Run-Time Check Failure #0 - The value of ESP was not properly saved across a
function call. This is usually a result of calling a function declared with
one calling convention with a function pointer declared with a different
calling convention.
This led me here:
http://blogs.msdn.com/b/mithuns/archive/2006/12/11/pay-attention-to-the-calling-convention.aspx
Which is what I based my fix on.
I have also noticed some warning during compilation which I haven't fixed but
thought I would mention anyway:

though as my C++ debugging skills are not exactly stellar. I am primarily a
Java programmer after all : )
I assume this is a platform specific issue of some type? It would be great to
get some feedback from others using different platforms and compilers to try
and narrow down the cause of the crash.

Hi Brad,
As you've spotted the GLU tessellation code has now been integrated
with the build of the core OSG library. I have taken the code from
Mesa 7.9, which in turn based it's GLU implementation on SGI base.
I'd expect most GLU implementations are based on the original SGI code
base, they might all have different bug fixes applied to them, perhaps
the Mesa code doesn't have a fix that the previous GLU library that
you were linking against had, or perhaps I've introduced a bug during
integration.
One advantage now is that you will be able build the GLU code

[osg-users] The next step using nvtt
Hi, After some playing with the new nvvt code path in VPB I have had some thoughts on possible improvements / extensions to what has already been done and would like to see if anyone else has anything to add. What I would like to support is the following: From a single VPB build / install I would like to be able to always use the fastest path available for texture compression. Without actually benchmarking the 3 possibilities I would guess, from fastest to slowest, the paths would be: - CUDA based nvtt (Nvidia site claims 10x faster than CPU path): requires an Nvidia GPU - OpenGL context based ARB_COMPRESSION : ATI or non-CUDA Nvidia card - CPU nvtt : no suitable GPU available I did do some basic benchmarking between ARB_COMPRESSION and nvtt CPU based compression and found the VPB build using OpenGL compression was ~4-5 times faster (in total run time). This is obviously a very big difference in performance. For a project I am working on we will have no direct control over the hardware VPB will be running on so I need to ensure that a pure CPU solution is available. However I don't want to slow down the builds unnecessarily if a suitable GPU is installed. Before I start trying to code this, does this sound feasible / desirable? Robert, I know you mentioned that you would be looking into integrating nvtt at some point into OSG. Would this sort of change fit more naturally into some kind of general OSG texture tools plug-in / utility or am I best just to focus on VPB for now?

Re: [osg-users] OT: VS2010 LNK2005 problem related to ostringstream
Hi, Unfortunately I can't offer a solution, but I thought I would mention I have come across this exact problem and have also pulled my hair out trying to find a solution. This same problem exists when building virtual planet builder, linking with osgDB causes the multiply defined symbols. I had no other issues building the 3rd party libs and osg with 2010. The only way I could move forward was to allow multiply defined symbols (as has already been mentioned). I agree this seems dangerous and is not a solution but it has allowed me to continue working. So far it hasn't caused any issues with my vpb build. Given you have used the streams extensively without issue and it seems osgDB is the source of the trouble, have you had a look to see if there is any discernable difference between your code and that in osgDB ? I would love to find a solution to this.

[osg-users] Visual Studio 2010 binaries
Hi All, I have built OSG, VPB and many of the 3rd party libraries using Visual Studio 2010 (trying to decide whether to upgrade). I have just uploaded them in case anyone else might find them useful: http://members.iinet.net.au/~bchrist/OSG-Rev11685-Binaries-2010-x86.zip.zip (today's trunk) http://members.iinet.net.au/~bchrist/VPB-Rev1013-Binaries-VS2010-x86.zip (today's trunk) http://members.iinet.net.au/~bchrist/OSG-3rdParty-VS2010-x86.zip http://members.iinet.net.au/~bchrist/GDAL-1.6.3-Apps-VS2010-x86.zip I had to submit a very small patch to osgTerrain (missing include) and have had to make some small changes to the DirectShow plug-in (not yet submitted) but other than that OSG built without issue. VPB compiled fine but I did get a link error against osgDB which I couldn't resolve (duplicate symbol for a destructor of an iostream or something) but I forced the generation of the dll and it runs without any (obvious) issues. The 3rd party libraries included are: free type gif glut jpeg png tiff squish zlib gdal (no debug) collada (no debug) curl (no ssl) DirectShow (you still need to install the Windows SDK to build the plug-in) Cheers, Brad DISCLAIMER:--- This e-mail transmission and any documents, files and previous e-mail messages attached to it are private and confidential.

Since I didn't receive any input or feedback on my previous inquiry, I'm assuming no one has used osgSim very much in an extensive setting.?.? At any rate, I've done some further investigation. It appears that performance is very poor when HAT inquiries are randomly called in different portions of the code via the osgSim::HeightAboveTerrain::computeHeightAboveTerrain(.) method. On the other hand, if HAT points via hat.addPoint() are collected up and then computed (intersections) in one place, performance improves. I'm assuming that this is the correct usage for OSG?

I would like some feedback from someone in the know on osgSim so I know what the proper usage is for maximum performance.

Re: [osg-users] Fix for adding / removing layers / optional layers using VPB
Hi Torben, I have replied on the osg-user list rather than submissions, hope that's ok. I cant say exactly what Roberts plan for optional layers was / is but I can tell you how I am using them. Optional image layers have their images stored in a separate directory structure from 'normal' layers. For example, when not using optional layers, all meshes and images will be stored in a directory structure such as: root/ earth.ive earth_root_L0_X0_Y0/ earth_subtile_l_X0_Y0/ If you then add another 'normal' layer, no new files or folders are created, the new imagery is just included (by default) in the existing .ive / .osgb files. When you add an optional layer, all the new imagery is stored under a separate directory. In the case of the above example: root/ earth.ive earth_root_L0_X0_Y0/ earth_subtile_l_X0_Y0/ MyOptionalLayer/ earth_L0_X0_Y0_l1.dds etc I am not sure exactly how loading layers is handled by the default Terrain Technique (I am using a custom one) but one big advantage I gain is that it allows me to load optional layers on demand. If all the imagery for a layer is contained in a single .ive / .osgb file, then this must be loaded as one, regardless of wether all the layers are actually being displayed. With the optional layer approach, it is possible to only the load the imagery that is currently being viewed. This is important for my project as our clients can often have a low bandwidth connection to the map server. This enables us to make a large number of layers available without effecting the load time of the base tiles. My standard setup for VPB generated databases is to only have one 'normal' layer with data such as blue marble. This acts as the default layer that is always available. All other imagery layers are added as optional layers. I hope that makes some sense.

Re: [osg-users] Shader composition, OpenGL modes and custom modes
Hi, Sounding great so far. A lot to digest! I have a couple of questions. One thing I am not clear on is how the rules for injecting a Shader into a ShaderMain would work. This is an area I have had difficulty with in my own shader assembly approach. For example, how will it be possible to change the order in which shaders are applied? As a contrived example, I might want to use the material color of a fragment as the input to my lighting shader, and then blend my textures with the result. Alternatively, I might want to first blend all my textures, then use this color as the input to the lighting shader. How would I specify these kind of rules? Another area I am not clear on is how (if at all) we will be able to avoid doing the same calculations many times for a single vertex or fragment. Say, for example, we need the ec position of a vertex as an input to several of our vertex Shaders. Would each shader have to recalculate this value independently? This shouldn't be a major hit to performance in most cases but it is obviously less efficient than just doing the calculation once. Then again, maybe the compiler can figure this out for us.

This would mean that ShaderComponent would then just have a list of one or more osg::Shader. These Shaders would then be grouped into ones that affect the vertex, geometry and fragment programs. The osg::Shader class would have some new API for setting up the inject code, this could be empty/inactive in a default constructed osg::Shader, so wouldn't affect how we use osg::Shader/osg::Program right now. It's only when shader composition comes into play will these extra fields be queried. 3) StateAttribute would have a ShaderComponent that implements the shader functionality, this ShaderComponent would typically be shared between the same type of StateAttribute. The StateAttribute attribute would also provide osg::Uniform that pass in the values to the associated ShaderComponent, these osg::Unfirom will be applied by the existing StateAttribute::apply(..) method. This is approach I've been discussing before (save for the ShaderSet rename.) 4) osg::State will maintain a current list of enabled ShaderComponent's, this list of pointers will form a key to search for the appropriate osg::Program to apply to achieve that functionality. The way that the osg::Program will be wrapped up and cached is within a ShaderAssembly. osg::State would internally manage the creation of ShaderAssembly, and cache of these and apply the osg::Program they contain. Lazy state updating in osg::State will seek to minimize the times that the state is changed between ShaderAssembly. When the set/list of enabled ShaderComponent's changes a the appropriate ShaderAssumbly for this set of ShaderComponent is then lookup in the ShaderAssembly cache. If non apporpriate ShaderAssembly is found then the ShaderComposer is invoked to create a new ShaderAssembly which is then cached and made current. 5) A ShaderAssembly is an internal implementation class so not something a user would normally worry about, only the ShaderComposer or subclasses from it would need to know about it. A ShaderAssembly has the final osg::Program that is applied to OpenGL, this osg::Program is composed on the osg::Shader's provided by the osg::ShaderComponent, and also an automatically created osg::Shader main for each of the vertex, geometry and fragment parts osg::Program. The automatically generated shader mains are wrapped up in a ShaderMain class that has a list of osg::Shader that contribute to it, these osg::Shader are pulled in from the ShaderComponent's that are associated with the ShaderAssembly. The individual osg::Shader that assigned to a ShaderMain provide the code injection details that enable the ShaderComposer to create the final main() code that gets placed in the ShaderMain's automatically generated osg::Shader.

Hi, I would just like to comment on this: Ooo I hadn't thought about providing a mechanism for computing vertex positions on the CPU, but this would be very very useful for the quandary of using shaders to modify the vertex positions dynamically. The mechanism would need to know the uniform state and the ShaderSet that are relevant, so the StateAttribute might be the place to couple this. Or perhaps the ??IntersectionVisitor etc. could accumulate StateSet's and pick out the StateAttribute that effect the vertex position. I have recently run into this issue when doing billboarding within a vertex shader. To still allow picking I have had to write a custom routine that operates on only this section of my scene and mask it out of the general picking mechanism. This is quite a painful and time consuming process. I believe this issue will become very common as more work is moved into vertex and geometry shaders. As such I would be very keen to see this sort of functionality incorporated into the core. There is also some danger in doing so though, as this could make picking operations much more expensive. After all, I moved the billboard calculation from the CPU to the GPU for a reason : ) Cheers, Brad -Original Message- From: osg-users-boun...@lists.openscenegraph.org [mailto:osg-users-boun...@lists.openscenegraph.org] On Behalf Of Robert Osfield Sent: Wednesday, 30 June 2010 5:05 PM To: osg-users@lists.openscenegraph.org Subject: Re: [osg-users] Shader composition, OpenGL modes and custom modes Hi Roland, On Tue, Jun 29, 2010 at 10:22 PM, Roland Smeenk roland.sme...@tno.nl wrote: 1) Provide a way of encapsulating all the details required to contribute a single chunk of functionality that will be combined with other active ShaderSet to provide final composed osg::Program. Isn't this what I solved with the ShaderMode class? I believe ShaderMode and ShaderSet are pretty close in concept, the fit a similar role and functionality granularity. Implementation and usage wise they differ, but they have lots of similarity, i.e. they are both big cats, but ones a tiger and ones a lion. Or is it that you are trying to separate the shader mode associated with a StateAttribute from the part that is responsible for adding of the piece of shader functionality. My currently thought is that the various StateAttribute subclasses would provide a standard ShaderSet instance that implements their functionality, but also make it possible to override this standard ShaderSet with custom ones. For instance we might have a standard implementation of osg::Light, but we also want to enable users to have their own implementation, by just providing their own MyCustomPerPixelLightShaderSet. There might also be cases where a osg::StateAttribute subclass might dynamically decide which ShaderSet to use depending upon how it's configured - this would be if we wanted to reduce the number of uniforms by having more pre-configured shaders. In my contribution I implemented a single ShaderMode that implements all fixed function lighting possibilities. For new types of lighting it seems more logical to indeed make a more fine grained breakup of ShaderModes. However there's a (minor) advantage to this one size fits all lighting code currently. To enable or disable lighting you simply can override a single mode. In the case where there are multiple lighting modes (directional, spot etc.) overall disabling of lighting needs to be done per lighting type. It might be needed that multiple ShaderSets implementing the same aspect/feature can be switched on or off all together with a single override. This will also be needed for instance in shadow map creation where in the first pass you would like to render geometry into a shadowmap as cheaply as possible and therefore without lighting. Perhaps multiple ShaderSets implement a the same aspect/feature in the final program that need to be disabled or enabled collectively. Again in the case of shadowmap creation you would like to only render geometry, no texturing, no lighting, no fog, but you do want to take into account skinned mesh deformation, wind deflection etc. I don't yet have any concrete plan on how to manage the case where multiple GL enums control particular features. It might be that it'll be best to map some of the controls to uniforms that enable one to toggle features on/off such as lighting, but it might also be that we it could be best to just pass the all modes on the StateAttribute when asking for the appropriate ShaderSet to use and let it decide what to use. This type of issue I expect to fall out of experience with implementing various fixed function functionality such as Lighting. 3) The ShaderSet would contain list osg::Shader objects, these osg::Shader objects would target which ever part of the overall program that the ShaderSet effects - be in multiple osg::Shader for vertex programs,
Re: [osg-users] New problem with VPB serializer
Hi,
I just looked over last night's email and realized what I wrote is about as
clear as mud.
The problem is this: when the build options are read from disk by the
readOptionalLayerSet method in BuildOptionsIO a leading empty string is
retrieved from the stream resulting in an optional layer being added (which
doesn't exist in the original file) with an empty name.
Cheers,
Brad

Hi,
I have just tracked down another issue with the VPB serializer. This time the
issue arises when you try to add an optional layer (nb: this fails at an
earlier point with the code in trunk at the moment, I will be submitting a fix
for that tomorrow, though the issue can be demonstrated without it).
When build options that contain an optional layer are serialized an empty entry
is added to the list.
e.g.
OptionalLayerSet 2 {

}
I believe the bug is in BuildOptionsIO.cpp, probably in the SetSerializer
class, thought I haven't managed to track it down exactly yet.
The attached files can be used to reproduce the error.
original.source is a copy of the build_master.source that was written out when
I tried to add an optional set.
If you run:
osgdem -s original.source --so original_resaved.source an error will be
produced as the file cannot be read.
I have also attached 'fixed.source'. This has had the removed (note that the
number of items in the set is still set to 2). This file can be de-serialized
and then re-serialized but the result has the extra included. This can be
done by running:
osgdem -s fixed.source --so fixed_result.source

Re: [osg-users] VPB master fails to patch an existing database (serialization error again?)
Hi, I have just manged to get some time to look into the issue and have found what appears to be a problem. The build compatablity check that is failing, the previous and current DatabaseBuilder having a different number of layer image options, seems to be the correct state when adding a new layer. If I understand this correctly, the check should not be in the code as this will stop you from ever adding new layers to an existing database. I will submit a patch that removes this check but thought I would see if anyone knew if it is there for a reason that I am missing. The relevent code is in BuildOptions.cpp in the compatable method. I have now created a more complex test which is failing in a different way so back to the debugger.. : ) Cheers, Brad -Original Message- From: osg-users-boun...@lists.openscenegraph.org [mailto:osg-users-boun...@lists.openscenegraph.org] On Behalf Of Christiansen, Brad Sent: Wednesday, 23 June 2010 1:16 PM To: OpenSceneGraph Users Subject: [osg-users] VPB master fails to patch an existing database (serialization error again?) Hi, I seem to have uncovered another issue with the recent changes to VPB. If I try to do a trivial patch of an existing database I get the error: Build configuration invalid : Previous build options not compatible with new build options, cannot patch database. To reproduce the problem I am using the following simple test case: -create the database: vpbmaster --bluemarble-west -t hills.png --bluemarble-east -t hills2.png -o ./out/test.osgb -then patch it: vpbmaster --patch ./out/test.osgb --add --layer 1 --bluemarble-east -t hill3.png This used to work without issue. I have started tracking down what is going wrong and it seems to be failing in BuildOptions.cpp method: bool BuildOptions::compatible(BuildOptions rhs) const. This method returns false as the number of image options are different ( if (_imageOptions.size() != rhs._imageOptions.size()) return false; ). It seems that when the new .soure file is written out (in the test case above, the file: test.osgb.1.source) it contains two identical ImageOptions. I will keep investigating and post any further information, or hopefully a fix.

Re: [osg-users] New osgTerrain serializer not calling TileLoadedCallback
Hi, Thanks. I have managed to get it to work by writing out a dummy value to the end of the terrain tile record and then calling the TileLoadedCallback when I read the value back in but as I said, this is a very ugly hack. My question now is, at this stage, is it a good idea to rely on the TileLoadedCallback mechanism within the current osgTerrain design? I think I can implement what I need without using it if it looks like this may disappear in future versions (given it is currently broken with the new serializers). If it is likely that the feature will stay I will just fall back to writing out .ive databases for now until a good solution can be implemented (I need to generate some new databases very soon for some demos).

Subject: [osg-users] New problem with VPB serializer
Hi,
I have just tracked down another issue with the VPB serializer. This time the
issue arises when you try to add an optional layer (nb: this fails at an
earlier point with the code in trunk at the moment, I will be submitting a fix
for that tomorrow, though the issue can be demonstrated without it).
When build options that contain an optional layer are serialized an empty entry
is added to the list.
e.g.
OptionalLayerSet 2 {
AnOptionalLayerName
}
I believe the bug is in BuildOptionsIO.cpp, probably in the SetSerializer
class, thought I haven't managed to track it down exactly yet.
The attached files can be used to reproduce the error.
original.source is a copy of the build_master.source that was written out when
I tried to add an optional set.
If you run:
osgdem -s original.source --so original_resaved.source an error will be
produced as the file cannot be read.
I have also attached 'fixed.source'. This has had the removed (note that the
number of items in the set is still set to 2). This file can be de-serialized
and then re-serialized but the result has the extra included. This can be
done by running:
osgdem -s fixed.source --so fixed_result.source
Cheers,
Brad

[osg-users] VPB master fails to patch an existing database (serialization error again?)
Hi, I seem to have uncovered another issue with the recent changes to VPB. If I try to do a trivial patch of an existing database I get the error: Build configuration invalid : Previous build options not compatible with new build options, cannot patch database. To reproduce the problem I am using the following simple test case: -create the database: vpbmaster --bluemarble-west -t hills.png --bluemarble-east -t hills2.png -o ./out/test.osgb -then patch it: vpbmaster --patch ./out/test.osgb --add --layer 1 --bluemarble-east -t hill3.png This used to work without issue. I have started tracking down what is going wrong and it seems to be failing in BuildOptions.cpp method: bool BuildOptions::compatible(BuildOptions rhs) const. This method returns false as the number of image options are different ( if (_imageOptions.size() != rhs._imageOptions.size()) return false; ). It seems that when the new .soure file is written out (in the test case above, the file: test.osgb.1.source) it contains two identical ImageOptions. I will keep investigating and post any further information, or hopefully a fix.

Re: [osg-users] VPBMaster failing - build_master.source not loaded correctly.
Hi Robert, I have just completed an update and build and all seems to be running correctly again. Thanks so much to yourself and Wang Rui for solving the issue (especially given I was kicking back on holidays at the time! : ). I will now be able to move on to testing your fixes to the DB pager, hopefully today, if not tomorrow.

Hi Brad, I have now reviewed Wang Rui's fixes and rather than adopt these directly, I've learnt from them what the problem was - which enabled me to recreate the problem under Linux, so can confirm now that it's now Windows specific issue, it was just I wasn't quite recreating the same usage. With the new knowledge of the problem in hand I've implemented a variation on Wang Rui's fix which handles the failing case as well as provides syntax which is a bit more succint than Wang Rui's changes and bit closer to the original .osg style syntax. I've checked my changes into OSG svn/trunk, could you do an svn update and let me know how you get on.

Re: [osg-users] VPBMaster failing
Hi, Thanks. The error is: Error: no destination graph built, cannot proceed with build. I am just starting the run with a break point on createDestination() in DataSet.cpp from osgdem to see why it isn't creating the destination now.
