Re: [osg-users] converting .osg to .obj
Hi Scott, The fastest way is to use osgconv application, which automatically loads osgdb_obj plugin for writing: # osgconv filename.osg filename.obj It seems the osgdb_3ds plugin does not support writing at present. But this will soon be solved by Sukender's submission, I think. :D 2009/11/25 Scott Martin smar...@martinarts.com: Hello, Is there a way to convert an .osg file to an .obj file, a .3ds file, or something similar.

Re: [osg-users] picture in picture...
Views get rendered in order added. (at least in single threaded mode) Just add your 'in picture' viewport last, where you want it. You will need to turn off clearing of the colour buffer if you want to see your main scene through the picture . And maybe call setAllowEventFocus(false); on the views camera to prevent it nicking mouse keyboard events. 2009/11/24 Tueller, Shayne R Civ USAF AFMC 519 SMXS/MXDEC shayne.tuel...@hill.af.mil All, This is probably a silly question but what’s the best way to do a “picture in picture” using CompositeViewer?

Re: [osg-users] [osgOcean] Wake effects?
Ok I reckon the water.frag has used up the maximum allowed uniforms for that card, I've come across this issue before with the 7 series cards. There are some tricks to get around this, so I'll see if I fix it. Is there any chance you could set the notify level to osg::NotifySeverity::INFO and then pipe the output from oceanExample to a file and send it to me?

Re: [osg-users] broken osgconv.exe
Ted, I downloaded the osg precompiled package you are using (openscenegraph-all-2.8.2-win32-x86-vc90-Release.zip), and I checked that indeed, the osgdb_ive.dll depends on a zlib1.dll that was compiled with VS 2005 SP1 (which is weird). I presume it is also the case of libpng, curl and tiff. So, to move on, you have to recompile osg from the sources using the vc90 dependencies, or install the VC++ 2005 redistribuable packages (there are two if my memory serves me right ), I think you didn't install the 2005 *SP1 * redistribuable package (http://www.microsoft.com/downloads/details.aspx?FamilyID=200b2fd9-ae1a-4a14-984d-389c36f85647displaylang=en) .

Now if I don't set geom-setUseVertexBufferObjects(true); everything works
fine. Do you still need a valid render context or a valid viewer to be able
to clean up the VBO's?

Re: [osg-users] PagedLOD/ProxyNode design discussion
Hi,
got another opinion on the PagedLOD and ProxyNode topic. :-)
We have been using both nodes for stuff like pseudo loaders as well and
I would recommend to change the interface a little bit. There should be
a common interface for all pageable nodes like:
class PageingNode : public Group {}
and then:
class ProxyNode : public PageingNode {}
class PagedLOD : public PageingNode {}
and now one can easily add custom implementations on top of PageingNode
like
class MyCustomNodeWhichRefreshesTheSubgraphEvery10Seconds : public
PageableNode {}
The design of the databasepager would be cleaner as well.

Richard

Re: [osg-users] PagedLOD/ProxyNode design discussion
Hi Chris, I can't help but feel that you are trying to making this more complex than it needs to be. First up pre-loading a plugin to handle extensions is easy, as it's already built into the core OSG. Try -e ext which preload the plugin of the given extension. osgconv -e ModifyTerrain model-in.ive model-out.ive This would preload your ModifyTerrain plugin and it then can handle all file loads and decide what to do with them. osgviewer supports the same option. Programmatically it's just a single line call to: osgDB::Registry::instance()-loadLibrary(osgDB::Registry::instance()-createLibraryNameForExtension(ModifyTerrain); Another aspect of the way the plugin mechanism works is that if you just added the extension directly to the osgconv line the ModifyTerrain plugin would be loaded first automatically anyway, so there after can handle all filenames as it'll be the first plugin in the list. osgconv model-in.ive.ModifyTerrain model-out.ive Finally, changing osgconv's to add support recursion and adding your optional extension on to internal should be trivial. I really can't see a need or great value in adding the extra complexity of a getCombinedFilename() or a osgDB::ModifyFilenameCallback. The later really seems like a silly leave of embedding extra callbacks to modify narrow features. There are already plenty of ways of overriding the read file, adding more isn't going to make the code any less extensible or flexible, it's just going to complicate things. Robert.

This seems like the most likely to succeed, so I've been investigating how this would interact with the recursion code for osgconv. The problem I see is that hooking into the ReadFileCallback would work for normal scenegraph cull traversal loading (like osgViewer or any other app who is just loading via the pseudoloader). However, recursive osgconv can't just let the scenegraph do the loading for it in pagedLOD::traverse(). For one, it has to load all LODs. It also has to load each external file individually so that it can configure the loading and saving context properly (to preserve relative paths and such that are specific to each external child). But ReadFileCallback does the actual loading itself, rather than just providing the pathname of the file that the node in question (PagedLOD or ProxyNode) intends to load (which is what the too-specific getCombinedFileNameWithSuffix() method I made did). I feel that irrespective of anything to do with modifyterrain, pseudoloaders or suffixes, the idea of a getCombinedFilename() method (note, without WithSuffix) has merit. It simply decomposes the conglomerated merge-path-with-filename and load-merged-path methods into two discrete methods. In this way, the merge-path-with-filename operation doesn't have to be re-created elsewhere (in osgconv), which would be poor design. This issue arises even if we completely ignore pseudoloader suffixes. As an alternative, I investigated the potential of FindFileCallback. It is more along the lines of the more-minimal operation this calls for, but it too is called only from within the actual load operation, and so it's not what osgconv needs. There doesn't appear to be a way for osgconv to ask what-file-should-the-PagedLOD-try-to-load without actually calling for that file to be loaded. Altering FindFileCallback seems like taking it farther afield from its intended purpose, and therefore a bad idea. I'm sure you understand that I'm trying to keep application-specific implementations out of osgconv. The goal is to permit osgconv to do a bulk, recursive convert of a database while allowing a transparent pseudoloader to function during load. I'm trying to avoid messing with the persistent stored data attributes of the PagedLOD (like child names, and database path) so that when the modified database (which no longer needs the pseudoloader, because the modifications have been incorporated) is resaved, no trace of the pseudoloader remains. This can be used to freeze terrain modifications into a database so that they no longer need to be applied at runtime. I understand your wish to avoid domain-specific changes like the PagedLOD suffix. Would it be acceptable to instead devise an osgDB::ModifyFilenameCallback class, with an entry for it basically everywhere that FindFileCallback is available. PagedLOD's getCombinedFilename() would utilize this to expose load-time-filename-alteration without disrupting the stored child filename. In this

There is no callback mechanism for catching calls to dirty(); Perhaps you could use an update callback that checks on each new frame whether the modifiedCount has changed since the last frame and then do your image processing then.

Hi,
got another opinion on the PagedLOD and ProxyNode topic. :-)
We have been using both nodes for stuff like pseudo loaders as well and
I would recommend to change the interface a little bit. There should be
a common interface for all pageable nodes like:
class PageingNode : public Group {}
and then:
class ProxyNode : public PageingNode {}
class PagedLOD : public PageingNode {}
and now one can easily add custom implementations on top of PageingNode
like
class MyCustomNodeWhichRefreshesTheSubgraphEvery10Seconds : public
PageableNode {}
I can see value in this, but I'm not sure how easy it would be to come
up with the PagingNode base class - it can't just subclass from
osg::Group.

The .osg plugin is extensible so you only need to pull in the NodeKits you need. Hope is on the horizon for the an extensible binary format side of things - Wang Rui has proposed a new extensible native binary format, so this may well be able to us to spilt the binary support for each NodeKit over the range of classes.

Re: [osg-users] Databasepager + multiple views + different camera positions = memory leak?
Hi All, I've now checked in the new testbed example, osgmultiviewpaging, for sorting out database paging. It's just a first cut so far, but I'll add to it as we go on. An svn update will get this example. This example we'll need to add support for specifying animation paths for each of the views, and then share animation paths/datasets details that enable us to reproduce the memory issues. I need members of the community to pitch in with the testing.

I'm guessing that somehow your system picks up some other zlib1. The zlib module is very common so there is a good chance you already got it embedded with other software. Try setting the PATH explicitly like: set PATH=vc90_dependencis\bin;vc90_osg\bin before running dependency walker or osgviewer dependencywalker shows that these pluggin dlls are still looking for MSVCR80.DLL *and* MSVCR90.DLL No, osgdb_tiff, _curl and the other plugin in your list depends on msvcr90.dll. However they also depend on many other modules that may, in turn, depend on whatever runtime they were compiled against. Hitting f9 in dependency walker will show you the full path to all listed dlls And the other pluggins can't find MSVCR90.DLL. I think this is a flaw in dependency walker. I don't have your system, but my system reports this too where top dependency msvcp90 depends on msvcr90. If this is the case also for you then just ignore.

[osg-users] how to suspend rendering context thread
hi all, When I use osgMFCViewer, I create multiple rendering context,that's to say there are many HWND, each HWND is related to one Render thread ,so much CPU resource is taken up. This is what I want to do: When one viewport is maximazed, the others will be hidden ,so these hidden context do not need continue the rendering. I want to suspend and resume some rendering thread depends on message CWnd::OnSize(UINT nType, int cx, int cy ). I checked the MSDN and find that the parameter nType can be one of the following values SIZE_MAXIMIZED Window has been maximized. SIZE_MINIMIZED Window has been minimized. SIZE_RESTORED Window has been resized, but neither SIZE_MINIMIZED nor SIZE_MAXIMIZED applies. SIZE_MAXHIDE Message is sent to all pop-up windows when some other window is maximized. SIZE_MAXSHOW Message is sent to all pop-up windows when some other window has been restored to its former size. My problem is that I never get SIZE_MAXHIDE or SIZE_MAXSHOW message. Is there anyone who has used SIZE_MAXHIDE or SIZE_MAXSHOW message? Or is there any other way to reduce the CPU resource usage？ thanks in advance best regards forest___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] VBO's - lifetime.
Hio Nico,
I've attempted to reproduce the cash using a scene graph that I force
to use VBO's, and the run the viewer for a frame() or run() then
destruct the viewer, then the scene graph - along the lines of your
code fragment, but it runs reliable on my Kubuntu 9.04 64bit system
with svn/trunk.
Here's lies the problem with using code fragments - I just don't know
if it you did something different in your code to what I've put
together and this accounts for the difference we are seeing, or
whether it's just thread timing/unitialized variable/different
OS/different compiler/different rev of the OSG. Compilable examples
that can be tried on both systems eradicate many of the variables as
to the cause of the problems, I know this is more work, but it's far
quicker for trying to isolate bugs.
Until I can reproduce the problem there isn't too much I can do at my
end. What I'll now do is look at J.P. example to see if that help
track down one or more of the problems with the VBO clean up. Whether
any solution to J.P's observed problems will address the one you are
observing I can't say without being able to reproduce your problem.
Robert.

Re: [osg-users] CompositeViewer context cleanup and missing textures
Hi J.P, I've tried out your example and found that with paged databases and your supplied model everything works fine for the first viewer then on the subsequent viewer I get: Warning: detected OpenGL error 'invalid operation' at after RenderBin::draw(..) Warning: detected OpenGL error 'out of memory' at after RenderBin::draw(..) Warning: detected OpenGL error 'out of memory' at after RenderBin::draw(..) For none paged databases, even ones with texturing I'm not getting any errors though, for any of the viewer runs. I really don't know what this means if anything, perhaps just a coincidence. Curiously your database uses straight osg::Geometry meshes for geometry, while the ones of mine were built with osgTerrain::TerrainTile. Your database will be only loading the topmost tile so the DatabasePager won't actually be even playing a part, so I doubt this is part of the equation. While I can't see a particular pattern emerging, I can at least reproduce the issue. I'll try and remove the multi-view element to the equation as I wouldn't have thought use of CompositeViewer will be a particular problem for VBO/Texture object usage. Robert.

Re: [osg-users] [osgPlugins] osganimation plugin and static linking
Hey Robert, Thank you for the information. There is no application so far, but I am currently evaluating OpenSceneGraph for the purpose of being used as the 3D engine for a game development studio that I am planning on starting up. I have not gone through the whole GPL license yet. I assumed that the OpenSceneGraph Public License allowed me to freely distribute my binaries (meaning selling my games) though. Embedding the source code was a quick hack to avoid struggling with a static library issue (and I think that there is no way to have the osganimation plugin statically linked as of today). I have no intention to distribute source code ; I want to sell games, and probably use OpenSceneGraph to make them, if it suits my needs. I will double-check whether the OpenSceneGraph license lets me do that or not.

Re: [osg-users] CompositeViewer context cleanup and missing textures
Hi Robert, Jason, I would see similar crashes / missing textures, but only when previous context ID's were reused, and only when using paged databases. I'd sure like to see this fixed... I posted an example reproducing the issue on osg-users a while back but Robert was busy on the GLES port. Now that you're done, could you investigate that issue (which seems related to this one too) please? Note that the issue happened both with and without the texture pool support for me (in fact we spotted it in our app which is built on OSG 2.6). We worked around the issue temporarily by incrementing the context usage count so that context IDs are not reused, but it would be better of course if OSG cleaned up after itself correctly when a context was destroyed so that context ID reuse would work correctly. If you want me to repost my (and Jason's) latest code that reproduced the issue with context ID reuse, just ask. I think you can get it from the link Jason posted though.

Hello,

an access violation in GLBufferObjectSet::orphan when I try to destroy

using namespace osg;
ref_ptrNode node(new Node);
ref_ptrGeometry geom(new osg::Geometry);
// ... fill geom
geom-setUseVertexBufferObjects(true);
node-addDrawable(geom.get());
{
ref_ptrosgViewer::Viewer viewer(new osgViewer::Viewer());
viewer-setSceneData(node);
viewer-frame();
// render for a while
viewer = NULL; // The viewer is destroyed here
}
node = NULL; // This gives the access violation.
Now if I don't set geom-setUseVertexBufferObjects(true); everything
works
fine. Do you still need a valid render context or a valid viewer to be
able
to clean up the VBO's?

The OSG isn't the place for custom code, both for a licensing issues,
build issues and maintenance issues. The question really should be
how to avoid need for custom code in the core OSG. The use of custom
code embedded in the OSG code would suggest that the OSG doesn't
support particular features, or isn't extensible enough, or just the
that code is tackled in the wrong way.
Could you enumerate what custom code you are wanting to put it and
why? Perhaps we can figure a way to avoid the need for it completely.

Re: [osg-users] VBO's - lifetime.
Hi Nico, I've now modified the osgcamera example so that it can be used as tested bed for repeated construction of viewers and enabling of VBO's. The example is now checked into svn/trunk, could you please try it out on your system and see what errors you can pick up. Try the following command line: osgcamera -r 3 glider.osg And: osgcamera -r 3 --vbo glider.osg You can also try (which loads once and then shares the model between viewers): osgcamera -r 3 --vbo --shared glider.osg Press escape each time the view comes up to close the viewer and move on to the next one. With the first command line I get no errors, and the glider comes up correctly each time. When enabling VBO's with --vbo I get the correct model on the first frame, and on the two following viewers nothing comes up and I get errors, the output to the console I've copied in below. Adding the --shared doesn't have any effect. The good news is that I am getting GL errors which suggests that the VBO pool isn't being cleaned up or initialized correctly for the new contexts. There is chance that this will result in crash on your system, but only GL errors on mine. Could you please test osgcamera as above to see.

[osg-users] Problem with Camera::inheritCullSettings
Hi Robert -- I've encountered a problem with how parent Camera values inherit down to slave Cameras, and wanted to discuss it before I launched into coding a fix. Quick summary: master Camera clear mask doesn't inherit down to slave Cameras. As a workaround, I can loop over slave Cameras and set the clear mask manually. Example use case: On a multidisplay system, create a Viewer configured to setUpViewAcrossAllDisplays. Get the Viewer's Camera, set the clear color to blue and set the clear mask to 0. Then call run. The windows incorrectly clear to blue -- they shouldn't clear at all, because the clear mask is set to 0. I managed to divine that slave Cameras get their clear colors set in Camera::inheritCullSettings, if the CLEAR_COLOR bit is set. If I modify this code to also copy the master Camera clear mask down to the slave Camera, then I get the expected result (no clearing occurs). It seems like there are two ways to fix this: One is to just piggyback clear mask onto the CLEAR_COLOR bit, or we could also add another bit specifically for clear mask. The second way, I'm not sure about. But the name inheritCullSettings fails to imply that clear color, possibly clear mask, read buffer, and draw buffer are all set in that function. So I wonder if inheritCullSettings is the right place to inherit these values? Or should master-to-slave value setting be done somewhere else? I'd appreciate your input on this, and I'd be glad to code a solution if you can provide some direction.

got another opinion on the PagedLOD and ProxyNode topic. :-)
We have been using both nodes for stuff like pseudo loaders as well and
I would recommend to change the interface a little bit. There should be
a common interface for all pageable nodes like:
class PageingNode : public Group {}
and then:
class ProxyNode : public PageingNode {}
class PagedLOD : public PageingNode {}
and now one can easily add custom implementations on top of PageingNode
like
class MyCustomNodeWhichRefreshesTheSubgraphEvery10Seconds : public
PageableNode {}
I can see value in this, but I'm not sure how easy it would be to come
up with the PagingNode base class - it can't just subclass from
osg::Group.
I've seen the same situation -- the DatabasePager is really strictly tied to
ProxyNode
and PagedLOD.
Multiple inheritance also opens a can of worms.

Re: [osg-users] Multiple cameras with setRenderOrder(PRE_RENDER, i)
Hi,

I tried your code, then prerender.cpp, then parts of shadowMap.cpp of
osgParticle. All failed, (seg fault when images were not attached to textures,
and render fail when texture were not have dimentions of power of two), so
there had to have been something wrong with the framework I was executing the
code under.
some investigation found:
Code:
for( unsigned int i=0; i texture.getNumImages(); ++i){
texture.getImage(i)-ensureValidSizeForTexturing( 134217728 );
}
which was forcing power of two dimensions on textures. Interesting though was
that it was causing seg faults for texture which did not include images. I
will be looking into this some more.
thank you for your help

Re: [osg-users] PagedLOD/ProxyNode design discussion
Robert Osfield wrote: I can't help but feel that you are trying to making this more complex than it needs to be. Well, not _trying_. ;) Sometimes I am through ignorance. I did not know you could force preload that way without First up pre-loading a plugin to handle extensions is easy, as it's osgconv -e ModifyTerrain model-in.ive model-out.ive Another aspect of the way the plugin mechanism works is that if you just added the extension directly to the osgconv line the ModifyTerrain plugin would be loaded first automatically anyway, Ok, that definitely addresses one of the major issues. I can perhaps just rely on MODIFYTERRAIN intercepting all loads, and selecting which ones it wants to apply to. Finally, changing osgconv's to add support recursion and adding your optional extension on to internal should be trivial. I really can't see a need or great value in adding the extra complexity of a getCombinedFilename() or a osgDB::ModifyFilenameCallback. I'm not sure we're talking on exactly the same wavelength, but I was pretty sure that any approach I came up involving osgconv and suffixes would be frowned upon as adding extraneous application-specific functionality to osgconv. Which, obviously we both wish to avoid. Let me clarify what the issue really is, as I see it (since by necessity, you're not as immersed in the problems and requirements of this design as I have to be). The part that is still left unspecified is this. the pseudoloader has to mark the PagedLOD nodes (or their child filenames, either one works) to indicate which ones should be modified by MODIFYTERRAIN. If MT intercepts all load requests, it needs to know which ones it should actually modify, and skip the others (both for performance reasons, and you might want some data loaded unmodified). Additionally, in order for this flagging to work (and then disappear) during an osgconv conversion where the modifyterrain is being applied via the loader, the marking has to disappear and not be present in the re-saved PagedLOD nodes or their child filenames. Otherwise MT would RE-applied when the converted (and already modified) database was reloaded, which is undesirable. The point of conversion is to apply the modification and then be rid of the runtime modification overhead. This is why the original suffix was designed not to be saved as part of the PagedLOD, and why I am avoiding tinkering with the actual child filename in the PerRangeData. Those changes would stick with the converted database. One might think I could manually stick the suffix on the child filename, and strip it off once the child loaded. However, if the child unloaded and then reloaded during one osgViewer run, the modifyterrain effect would disappear on subsequent loads after the first. However, I think I have a solution that can work without modifying any core OSG code, and still meet all the transparency requirements. I'll use the plugin pre-loading technique to allow MODIFYTERRAIN to intercept all loads. When MT loads a subgraph, it will (at your suggestion, and similar to how it does now setting the database suffix) go through the subgraph and mark each candidate PagedLOD by attaching a custom osgDB::Options. It is my understanding from a brief review of the .osg saver (PagedLOD_writeLocalData) that the osgDB::Options field is not stored when the .osg file format is written, and this is by intention. So, I will use the osgDB::Options to indicate which PagedLODs should receive MT treatment. I plan to do this by adding a plugin string data to the Options object via setPluginStringData with a key/value of PSEUDOLOADERSUFFIX, .modifyterrain. I believe this is within the intended use of the plugin string data. When modifyterrain intercepts the load call, it appears to be provided the osgDB::Options object (from the PagedLOD object), so the pseudoloader can check for the presence of the PSEUDOLOADERSUFFIX=modifyterrain key/value on the Options, and decide whether to post-load-process the subgraph or not. (The alternative to not tracking the pseudoloader-marking state directly on the PagedLOD via the Options is to keep a list of child filenames needing the treatment as a singleton within the MT pseudoloader, but then ModifyTerrain would have to search that list for each load, which could have dire performance on large filename collections, depending on which container type was used.) I think this is practical. Do you have any comments or suggestions on this method before I code it? It should allow osgconv and osgviewer to be completely naive and oblivious to the presence of a pseudoloader using this technique, which is my goal. -- Chris 'Xenon' Hanson, omo sanza lettere Xenon AlphaPixel.com PixelSense Landsat processing now available! http://www.alphapixel.com/demos/ There is no Truth.

The osgcamera doesn't work either: osgcamerad.exe d:\tetra.osg GLBufferObjectSet::GLBufferObjectSet _profile._size=5248 GLBufferObjectSet::GLBufferObjectSet _profile._size=5184 Texture::TextureObjectManager::flushAllDeletedTextureObjects() _contextID=0 Texture::TextureObjectManager::discardAllDeletedTextureObjects() _contextID=0 _numActiveTextureObjects=0 osgcamerad.exe -j 3 d:\tetra.osg + New viewer GLBufferObjectSet::GLBufferObjectSet _profile._size=5248 GLBufferObjectSet::GLBufferObjectSet _profile._size=5184 Viewer ended -- Texture::TextureObjectManager::flushAllDeletedTextureObjects() _contextID=0 Texture::TextureObjectManager::discardAllDeletedTextureObjects() _contextID=0 _numActiveTextureObjects=0 + New viewer and crashes after the first viewer. I wrote down the callstack when the crash occurs in my application: void BufferObject::releaseGLObjects(State* state) const, with state == 0 void GLBufferObject::releaseGLBufferObject(unsigned int contextID, GLBufferObject* to), with contextID==0 void GLBufferObjectManager::releaseGLBufferObject(GLBufferObject* to) void GLBufferObjectSet::orphan(GLBufferObject* to) The osgcamera example with the slider doesn't work either. Again, the output is correct for the first renderer, but not for the second and third. Here is the output again: osgcamerad.exe -r 3 d:\glider.osg + New viewer Viewer ended -- Texture::TextureObjectManager::flushAllDeletedTextureObjects() _contextID=0 Texture::TextureObjectManager::discardAllDeletedTextureObjects() _contextID=0 _numActiveTextureObjects=0 + New viewer Viewer ended -- Texture::TextureObjectManager::flushAllDeletedTextureObjects() _contextID=0 Texture::TextureObjectManager::discardAllDeletedTextureObjects() _contextID=0 _numActiveTextureObjects=0 + New viewer Viewer ended -- Texture::TextureObjectManager::flushAllDeletedTextureObjects() _contextID=0 Texture::TextureObjectManager::discardAllDeletedTextureObjects() _contextID=0 _numActiveTextureObjects=0 osgcamerad.exe -r 3 --vbo d:\glider.osg + New viewer Enabling VBO Enabling VBO Enabling VBO Enabling VBO Enabling VBO Enabling VBO GLBufferObjectSet::GLBufferObjectSet _profile._size=13120 GLBufferObjectSet::GLBufferObjectSet _profile._size=640 Viewer ended -- Texture::TextureObjectManager::flushAllDeletedTextureObjects() _contextID=0 Texture::TextureObjectManager::discardAllDeletedTextureObjects() _contextID=0 _numActiveTextureObjects=0 + New viewer Enabling VBO Enabling VBO Enabling VBO Enabling VBO Enabling VBO Enabling VBO Warning: detected OpenGL error 'invalid value' at After Renderer::compile Viewer ended -- Texture::TextureObjectManager::flushAllDeletedTextureObjects() _contextID=0 Texture::TextureObjectManager::discardAllDeletedTextureObjects() _contextID=0 _numActiveTextureObjects=0 + New viewer Enabling VBO Enabling VBO Enabling VBO Enabling VBO Enabling VBO Enabling VBO Warning: detected OpenGL error 'invalid value' at After Renderer::compile Viewer ended -- Texture::TextureObjectManager::flushAllDeletedTextureObjects() _contextID=0 Texture::TextureObjectManager::discardAllDeletedTextureObjects() _contextID=0 _numActiveTextureObjects=0 osgcamerad.exe -r 3 --vbo --shared d:\glider.osg Enabling VBO Enabling VBO Enabling VBO Enabling VBO Enabling VBO Enabling VBO + New viewer GLBufferObjectSet::GLBufferObjectSet _profile._size=13120 GLBufferObjectSet::GLBufferObjectSet _profile._size=640 Viewer ended -- Texture::TextureObjectManager::flushAllDeletedTextureObjects() _contextID=0 Texture::TextureObjectManager::discardAllDeletedTextureObjects() _contextID=0 _numActiveTextureObjects=0 + New viewer Viewer ended -- Texture::TextureObjectManager::flushAllDeletedTextureObjects() _contextID=0 Texture::TextureObjectManager::discardAllDeletedTextureObjects() _contextID=0 _numActiveTextureObjects=0 + New viewer Viewer ended -- Texture::TextureObjectManager::flushAllDeletedTextureObjects() _contextID=0 Texture::TextureObjectManager::discardAllDeletedTextureObjects() _contextID=0 _numActiveTextureObjects=0 tetra.osg Description: Binary data ___ osg-users mailing list osg-users@lists.openscenegraph.org
[osg-users] Some overview of OSG and VPB databases
I've accumulated some notes over time about how OSG and VPB databases works, and I thought I'd share them here for others' enlightenment, and also to ask for corrections. I don't guarantee this is correct, it just seems to be correct based on my understanding. Perhaps someday this might make it into some sort of OSG Terrain Guide or something. Structure of a typical VirtualPlanetBuilder/OSGDEM terrain database Root OSG file looks like: CoordinateSystemNode: Top-level, defines ellipsoid shape of globe PagedLOD Child0:TerrainTile (lowest LOD of terrain model) Child1:Basename_root_L0_X0_Y0/Basename_L0_X0_Y0_subtile.osg (file containing LODs that cover the same extent as Child 0) A VPB TerrainTile (for example, L0_X0_Y0) looks like: TerrainTile (lowest LOD of terrain model) Locator (defines Coordinate System and Transform of TerrainTile) ElevationLayer HeightFieldLayer HeightField: UniqueID, Origin, X/Y Interval, SkirtHeight, Heights [Array] ColorLayer ImageLayer file Basename_L0_X0_Y0.dds SubTile Basename_root_L0_X0_Y0/Basename_L0_X0_Y0_subtile.osg looks like: Group PagedLOD Child0: TerrainTile Child1: Basename_L1_X0_Y0_subtile.osg (Another subtile like this one) PagedLOD Child0: TerrainTile Child1: Basename_L1_X1_Y0_subtile.osg ...more, similar PagedLODs may exist here... In operation, the Root OSG file is loaded by the caller. This file contains a TerrainTile with Color and Elevation data, so as soon as the initial root load is complete, there is a lo-resolution terrain surface visisble. OSG immediately begins cull traversal of this scene graph. During cull traversal, the PagedLOD node probably discovers that the currently visible child (child 0, with the TerrainTile) is insufficient LOD for the current view. The only alternate LOD is Child1, which is an external file. PagedLOD informs the DatabasePager to begin loading this external file and continues on the cull. The load operation has a priority level that hints to the DatabasePager how important this node is, allowing multiple loads to be queued according to how close each one is to the viewer. After the first cull operation is complete, a number of cull/draw cycles may execute while the DatabasePager thread completes loading and possibly compiling the loaded data for use in the scenegraph. During each cull operation that the loaded external child is not yet available, the PagedLOD re-requests the child node to be loaded. This allows the priority of the node in the queue to adjust if the viewpoint moves prior to the node getting loaded. When ready, the DatabasePager inserts the loaded subgraph (see structure of Basename_L0_X0_Y0_subtile.osg) into the scenegraph. At this point, the top PagedLOD is satisfied that it has an appropriate LOD, and subsequent cull operations will traverse the Child1 of the top PagedLOD Node. Child1 itself contains a non-trivial subgraph. At the top of the subgraph are several PagedLOD nodes. Each of these contains its own Child0 LOD, which is not an external file but a TerrainTile complete with ElevationLayer and ColorLayer already loaded in and compiled as part of the Basename_L0_X0_Y0_subtile. So, when the Root-level Child0 TerrainTile is replaced with the root-level Child1 external file, the Basename_L0_X0_Y0_subtile's Child0s immediately cover the exact same visual extent of terrain without any more loading delay. As soon as the Basename_L0_X0_Y0_subtile subgraph is merged into the scenegraph and traversed by cull, the PagedLODs in L0_X0_Y0 will evaluate their LOD criteria (typically expressed not as actual distance, but in realtive-apparent-size-on-screen) and most likely discover they too, are insufficient for the current view. At this point, each of the PagedLODs will decide to load their next LOD child (Child1). Because each of these children will be located at different locations with respect to the viewer, they will each individually determine a different priority, which the DatabasePager will respect when queuing the DatabaseRequest. PagedLOD class has several conditions. The base LOD class and the Group class beneath that require that the container (a std::vector) that contains the actual LODs must be contiguous – no empty slots are permitted in the container. The PagedLOD class defines a parallel container called PerRangeDataList, which is also a vector holding the LOD ranges and external filenames for each child that can be loaded. The contents of these two containers are associated only by the subscript of their contents. What this means in practice is that the LOD children in the Group must be loaded contiguously – no higher LOD can be loaded if a lower LOD is not already loaded. PagedLOD will

Re: [osg-users] [build] How to properly use the OSG_GL3_AVAILABLE CMake option?
Hi Robert and Paul, Thank you both for your replies. Your answers affirmed my own investigations into gl3. For Paul - my OSG project is being developed for Win32 x64. I have just moved it to Windows 7 x64. It is tied to Windows because it is designed to work in concert with other Windows commercial apps that will probably never be ported to Linux. My project is still in development and has a long term objective. My view is forward looking, so I am interested in embracing gl3 as development progresses. I am primarily developing for nVidia hardware, and am particularly interested in nVidia extensions to gl3 that they refer to as Bindness Graphics. nVidia states: Bindless Graphics refers to changes to OpenGL that can enable close to an order of magnitude improvement in the CPU-limitedness of graphics applications. Bindless Graphics has the following desirable properties: • The driver need not dereference a vertex buffer or constant buffer on the CPU in order for the GPU to use it. • Relieves the limits on how many buffer objects can be accessed at once by shaders • Buffer objects are accessed as C-style pointer dereferences in the shading language • Allows for dependent pointer fetches, enabling more complex scene graph structures to be built into buffer objects providing significant new flexibility in the use of shaders. Measurements have shown that bindless graphics can result in more than 7x speedup! Unfortunately the nVidia OpenGL SDK which usually provides code examples seems to be stuck at this time at the GeForce 8 gl2.1 level. Hopefully this will be updated sometime in the future. As it seems that I am at about the same juncture as everyone else with respect to gl3, I don't feel so alone or incompetent as I did when I first began asking questions. I plan to take Paul's advice and begin writing gl3 code. If I come up with anything useful I will gladly contribute it with a submission. I have found that the Red Book 7th Edition covers gl3 and gl3.1. I also found the book Beginning OpenGL Game Programming 2nd Edition by Luke Benstead has been updated to gl3. I have just ordered it, but don't have it yet. Thank you!

Re: [osg-users] Custom code in OSG core
Hi Robert and Paul,
Oh, I'm sorry I shouldn't have written core OSG: it's maybe more in osg
plugins I guess...
I have to load huge models. By huge I mean a few thouthands triangles but GB of
textures. Of course loading such a model simply leads to a std::bad_alloc. This
is why I posted something about lazy textures/images on the mailing list: I
must load the model but I don't want all the textures to be loaded at the same
time. Depending on what I want to acheive I may need:
1. To leave textures unloaded, but I want writers plugins to do as if the
texture was loaded (= the writer simply says the texture is abcd.jpg).
2. To load low-res textures (or maybe not loaded at all), but I want hi-res
ones to be switched when needed, especially when writing.
I don't expect solutions to be suited for realtime rendering. I only need
those huge models to be loaded, then processed (= modifiy geometry without
touching the texture or vice-versa, modify only a part of the scene...) and
written to disk for future rendering.
I got a few ideas for these needs:
- Add a noTexture option to readers that stores somewhere the path of the
texture file, and add an option to writers to do as if the texture was loaded
(but only write to the file the path of the image). This is why I have custom
code in reader/writers. But this is clearly an ugly solution as I need to
modify each reader/writer.
- Create a lazy image, which is loaded only when accessing pixel data. But I
don't know if it's easy, and how to do it (as discussed in the corresponding
post).
And a final note: all my code is given to osg-submissions once stable... I
won't violate the OSGPL/LGPL :)
So... any idea? If I can acheive this without modifying OSG source code, then
I'd be very happpy...
Thank you.

The OSG isn't the place for custom code, both for a licensing issues,
build issues and maintenance issues. The question really should be
how to avoid need for custom code in the core OSG. The use of custom
code embedded in the OSG code would suggest that the OSG doesn't
support particular features, or isn't extensible enough, or just the
that code is tackled in the wrong way.
Could you enumerate what custom code you are wanting to put it and
why? Perhaps we can figure a way to avoid the need for it completely.
Robert.

Re: [osg-users] [osgOcean] Wake effects?
Would it be possible to implement sort of a config option with 2 or more shaders for multiple quality levels? This would allow for the use of one shader if you have a more powerful card, or another shader for an older card.
