The scene is from part of a CBD area in Beijing, and it will be shown on a wall with four projectors at last. I use VDSM with additional PSSM support and customized shaders to provide real-time illumination and shadowing. And the compositor which is currently maintained in osgRecipes is used to add glow effect and final color grading. SilverLining SDK is used for sky and cloud rendering. The scene includes only a few refined building models, but with OSG's dynamic paging ability we can easily support very large city with nearly the same rendering quality. I will be glad to submit both the shadow and compositor functionality to OSG core at the end of this year, or at the beginning of next year (as Robert is busy at present :-) and hope it could be improved again and again and also help other develop their applications. Current city models may not be suitable for open source use so I may have to find and commit a copyleft set of models along with the coming submissions. It would be appreciated if somebody could provide me some at that time.

You'll be calling frame() yourself rather than run() so won't be able to utilize this feature, but you should be able to learn from it. Have a look at the ViewerBase::run() method in OpenSceneGraph/src/osgViewer/ViewerBase.cpp, in particular the use of checkNeedToDoFrame() which is used to decide whether a frame is needed or not.

In osgMFC example, it uses a thread and for loop to keep calling _osgViewer-frame(). It is a reason why the cpu keeps loading and it also depended on how large of volume data loaded. Now I have changed to call frame() on MFC OnPaint event. It can decrease much cpu usage. I also added to call frame() on mouse move, mouse wheel and size events for zooming and rotating the image. But all MFC events cannot be fired if the image is rotating by itself. Thus, I am thinking whether osg has an event to detect the image is rotating. I just found a solution to add MFC mouse button up and down to detect whether the user wants to rotate the image. Then I can do it all on MFC event.

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. I've used Dreamhost for a long time (2002) and they're pretty good. My DH site is not high-traffic, but they've been fairly reliable. More reliable than Valencia (though I don't know the reasons for Valencia's downtime). If you go with Git (and there's a lot of discussion about Git vs Hg -- I've used Hg more recently), I'd just use GitHub. They seem to have this stuff figured out. No sense badly reinventing git hosting. I do NOT think OSG should run our own repository at this stage of the game, even if we _CAN_. github also now have their own wiki, Gollum: https://github.com/features/projects/wikis Chances are, it's adequate to do the things that TRAC's Wiki already does. In that case, it's good enough for me. I could also possibly offer to host the website myself. I have a colo box in a datacenter in Denver that hosts all my website and my OSG binary downloads. I don't pay for metered bandwidth, I only pay a flat monthly cost. My current server might be adequate for the task, but it might be pushing it too. I could figure out what it would cost for a newer machine (I'm budgeting a new rackmount server right now for another project) and the monthly monetary costs. I'd volunteer to install and keep the machine running if the community could assist with the hardware and recurring expense. I've done this for some other not-for-profit organizations I work with. The bandwidth is not guaranteed throughput, but we can pay for a 10Mb or 100Mb pipe and get quite a bit of utilization out of them. 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'm probably not a good person to step forward for this. I especially know nothing about Wiki migrating, but even if we have to do that by hard, that's something non-sysadmin types could help with -- copying and reformatting a page and adding it to the new site. It might also be useful to see if there is interest in moving the Forum interface to the same hosting platform. -- Chris 'Xenon' Hanson, omo sanza lettere. xe...@alphapixel.com http://www.alphapixel.com/ Digital Imaging.

Subject: Re: [osg-users] Is the Z-Buffer linear or non-linear?
Hello,
I think I got it. Correct me if I am wrong, if I use an orthogonal projection I
get linear Z-Buffer values. If I use a perspective projection I get non-linear
values.
The Z-Buffer value (z') of a perspective projection is:
z' = (far + near) / (far - near) + 1/z ((-2 * far * near)/(far-near))
The Z-Buffer value (z') of a orthogonal projection is:
z' = 2 * ((z-near)/(far-near))-1
So, I use a orthogonal projection therefore I get a linear Z-Buffer.
I hope that is right.

Betreff: [osg-users] Is the Z-Buffer linear or non-linear?
Hello,
I am completely confused about the Z-Buffer. I thought it is non-linear
but now I read a lot in forums and now I am not sure about that. The reason
about this question is I want render linear depth values into a texture. I
think, I can do it with this shader:
varying float depth;
uniform float near;
uniform float far;
void main(void)
{
vec4 viewPos = gl_ModelViewMatrix * gl_Vertex;
depth = (-viewPos.z-near)/(far-near);
gl_Position = ftransform();
};
varying float depth;
void main(void)
{
gl_FragDepth = depth;
}
But the poor think is all other shader will be overwritten.
Now I use this:
_rendertarget-setInternalFormat(GL_DEPTH_COMPONENT);
_cam-setClearMask(GL_DEPTH_BUFFER_BIT);
_cam-setRenderTargetImplementation(osg::Camera::FRAME_BUFFER_OBJECT);
_cam-attach(osg::Camera::DEPTH_BUFFER, _rendertarget);
_cam-setRenderOrder(::osg::Camera::PRE_RENDER, 0);
But this is nonlinear, isn't it?
I hope someone can help me about this.
Thanke you very much.
Martin

I found strange problem after update to version 275.33 of nvidia drivers.
I see artifacts with shaders, i tried to find why.
Part of shader uniform variables are not work correctly.
i try to debug it with gdebugger and i noticed non-initialized values in part
of uniforms.
file src/osg/Program.cpp lines 672-673
Code:
_extensions-glGetActiveUniform( _glProgramHandle,
i, maxLen, 0, size, type, name );
Later i found that names of array variables coming with [0]. example -
%name%[0]
i tested with 266.58 they coming without [0]
as result in _uniformInfoMap[Uniform::getNameID(reinterpret_castconst
char*(name))] = ...
we recording values with [0].
file src/osg/Program.cpp lines 213
Code:
inline void apply(const Uniform uniform) const
{
GLint location = getUniformLocation(uniform.getNameID());
if (location=0)
and here we can't get right location
i fix it, please look patch
Code:
--- a/OpenSceneGraph/src/osg/Uniform.cpp
+++ b/OpenSceneGraph/src/osg/Uniform.cpp
@@ -611,13 +611,13 @@ unsigned int Uniform::getNameID(const std::string name)

+UniformNameIDMap::iterator it = s_uniformNameIDMap.find(name.substr(0,

if (it != s_uniformNameIDMap.end())
{
return it-second;
}
unsigned int id = s_uniformNameIDMap.size();

+s_uniformNameIDMap.insert(UniformNameIDMap::value_type(name.substr(0,
name.find([)), id));
return id;
}
But i don't think that is a good solution.
Thank you!

Re: [osg-users] Draw Order/Culling with OpenFlight and Transparency
Hi Murray In my experience this looks like a classic transparency sorting issue/problem when you have objects that have transparency and their objects bounding volumes intersect,( I would also say this has little to do with you using open flight) This happens because for efficiency scene graphs sort transparent object at a geode level and not at a polygonal level, you find this has been discussed many time in many places If you look at you model its likely that you Rotors are in one object and then the windows/glass in another ( you might have more), is you the think of their 2 bounding spheres they will be intersecting, so as you view changes then how that are possibly sorted will change hence you get the punch through effect you see. One way to try to minimize this is to try and ensure when you create a model you don't create overlap transparency that overlap, this can be challenging to do depending on what you are modeling (you also have to watch for optimizers in Scenegraphs that try to chunk like materials and texturing in to one group as this can artificially introduce overlaps) You can also try to use a an opaque texture to represent windows/port holes (do you really need them to be transparent?) to help. You can create you own render bin that sorts at the triangle level for these models Gordon Tomlinson 3D Technology System Engineering Consultant Overwatch(r) An Operating Unit of Textron Systems __ WARNING: Documents that can be viewed, printed or retrieved from this E-Mail may contain technical data whose export is restricted by the Arms Export Control Act (Title 22, U.S.C., Sec 2751, et seq,) or the Export Administration Act of 1979, as amended, Title 50, U.S.C., App. 2401 et seq. and which may not be exported, released or disclosed to non-U.S. persons (i.e. persons who are not U.S. citizens or lawful permanent residents [green card holders]) inside or outside the United States, without first obtaining an export license.

I've tried this, and do not observe any appreciable improvement in rendering. I should point out that while the images I provided highlight the main rotor disc as the offending geometry, there are numerous other geometry elements (e.g., windows) that cause similar issues when viewed from various angles. I've stepped through the OpenFlight loader in debug mode and have observed that the rotors and windows are both being caught by the tests therein for translucent images and transparent materials, respectively. These tests result in the state sets being set as you've suggested, so it appears that OpenFlight loader is treating these nodes correctly. Any other ideas?

Actually we also implemented a node identification using child index... However I did not spot metadata related classes in osgWorks. Well, ok, I just had a very quick overview... Can you tell me where to look at? Thanks. Once you have a mechanism for identifying nodes that is not address-based and therefore works from one app invocation to the next, there is no need for any OSG-specific metadata classes. Such metadata can be stored outside the scene graph. However, if you want to associate metadata with the scene graph, you just use UserData. Perhaps we have a philosophical difference. In my opinion, a scene graph should not be turned into a general purpose data structure. The scene graph should be tuned and optimized for operations on spatial data such as rendering and intersection testing. Rather, the app should associate subgraphs of the scene graph with its internal app data structure, as visual representations of app-specific entities. Using this approach, an app can use the NodePathUtils in osgWorks to identify the relevant nodes to reference from its internal data structure. -Paul ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

We have been using OSG with nvidia physx for a driving simulation and we have jitter problem, where the cars and other objects in the scene (controlled by the physics) jitter annoyingly :). We believe that we update the scenegraph in a wrong way. In our code : There is a physx thread. There is an OSG library thread where we can add new entities, remove them, start rain effects, call an animation of a skeleton character etc. There is an OSG render loop thread, where osgviewer::...frame() is called. Our Nvidia physx thread produces new x y z pitch head roll values for the scene entities at 60Hz (or any other frequency we want). Physx thread calls the updateEntity() function of our OSG library thread. This function simply updates scene entities with matrixtransform::void setMatrix(const Matrix mat). In other words, we move an object with this chunk of code: Code: osg::Matrixd mxT = createTransformMatrix(x,y,z,h,p,r); mt-setMatrix(mx); Here what we tried: 1-we fed OSG lib directly whenever a physx output is produced (every 16.6 ms or so - 60Hz): there is jitter. 2-we maintained a queue of frames on OSG lib, fed OSG at the end of each frame() : there is jitter. 3-we implemented a sampling mechanism on this queue, where OSG requests the interpolated frame from the queue for the current timestamp : there is jitter. 4-we saved a few minutes long log of the physx to a file (many frames). Started a dummy thread, and fed OSG from this log. : there is jitter. When OSG works with 60FPS, and physx thread is running at 60Hz, there seems to be quite low jitter (sometimes unnoticeable) .

Hi JS Just little FYI , you can build texture atlases that repeat the caveat being they can only repeat in one direction so you can build vertical and horizontal sets :) I would also say the 1k verts per primitive set is lowish I would say you can look at 10k or more on modern hardware ( assuming you model(s) that many) Gordon Tomlinson 3D Technology System Engineering Consultant Overwatch® An Operating Unit of Textron Systems __ WARNING: Documents that can be viewed, printed or retrieved from this E-Mail may contain technical data whose export is restricted by the Arms Export Control Act (Title 22, U.S.C., Sec 2751, et seq,) or the Export Administration Act of 1979, as amended, Title 50, U.S.C., App. 2401 et seq. and which may not be exported, released or disclosed to non-U.S. persons (i.e. persons who are not U.S. citizens or lawful permanent residents [green card holders]) inside or outside the United States, without first obtaining an export license.

First, I've been focusing mostly on automatic optimizations that I can code up in some processing tool since we already do that now (we use osgconv to convert all our models to ive, so in the past week I've been writing my own tool that uses parts of osgconv, the osgUtil::Optimizer and some slightly modified classes to give better results on our data). My goal was to be minimally intrusive on my artist's work. But I think I'm at a point now that I'll have to get him to modify some things... For the number of transforms, I doubt I'll be able to do much to lower it, since it's a central part of our infrastructure that physics objects are attached to transforms (with the physics object's transformation being copied to the transform node each step). We might be able to get some other kind of relationship, but not in the short term. So I'll have to work on some other areas. Reducing the number of statesets is a worthy goal, I've already tried (building texture atlases mostly). I've gone from over 2500 statesets to 1345 in the stats I gave in my OP. The next steps will be to get my modeler to remove most parts of models set to render both sides (cull face off) and as Tim suggested removing textures set to REPEAT since those are two things that defeat atlas building sometimes. Using the INDEX_MESH | VERTEX_POSTTRANSFORM | VERTEX_PRETRANSFORM optimizers is a good idea, up until now I was compiling my tool against the same version of OSG as our simulator uses (2.8.3) though, so I couldn't use them. I'll see if I can backport them to that version and see if they give better results. About the state graph number. I guess that's pretty much proportional to the number of unique statesets in the graph? I'm at 1345 now, I guess if I get that number down it should reduce the number of state graphs? Tim mentions keeping a figure of about 1000 verts per primitive set in mind. That's good info. It's really hard to find numbers that you can relate to the stats you see in the OSG stats display. Thanks a lot, I'll keep working on it and keep you updated.

Re: [osg-users] Access violation in osg61-osg.dll?
Does it work in debug? If it does not debug should give you much more
info to track why you
Does the scene load in osgviewer.exe ?
A couple of reasonable guesses would be that
* you're possible mixing release/debug libs/dlls
* or you're mixing libs/dlls built with different compiler versions
VS2005/VS2008 etc
* or you're mixing versions of lib's/dll's that have different patch
levels

Hello everyone,
I have a really frustrating situation on my hands here. I've made a
simple application that loads a scene and then does something with it.
When I try to load certain scenes, my program crashes occasionally(!) in
release mode and gives me this error:
Code:
Unhandled exception at 0x72e39083 in Diploma.exe: 0xC005: Access
violation reading location 0x02f0b154.
Other times everything seems to be working perfectly.
The address of the exception seems to be pointing to osg61-osg.dll
The call stack looks like this:

However, we're now looking at ways of stream lining the work flow between modellers and programmers. At the moment the big sticking point is finding a model format that exports nicely from maya 2010 and Max2010 and is then read without issue in OSG. In the past the best results I've had was with Collada and max 2009 when exported using the Feeling software free collada exporter. However, as far as I know this isn't supported by max 2010. I noticed Feel Software have a commercial version of ColladaMax but without a trial version it's difficult to evaluate how it will perform will OSG's inbuilt loaders. So, I would be very interested to know what exporters (commercial or free) people are using to get their models out of Max and Maya and into OSG. Or indeed, if people have had to use custom loaders in their software to get consistent results. Our requirements are pretty basic (geometry, multiple texture coordinate sets, textures, material properties etc), but what is most important is that we can limit the amount of tweaking we need to do to get the models into OSG after export. We're happy to change version of OSG if there have been improvements in the area since 2.8.2.

Re: [osg-users] 3D model fomat
Hi Generally in many cases yes IVE's will/can help improve your runtime performance especially load time, when converting from other formats such as 3DS, FLT to IVE optimizations can be done that can aid the run time as well , but could model a lot of that as but most folks don't model that way these days, it's a skill that being lost Whatever the run-time you use it is generally found that the native binary format IVE in the case of OSG will typically outperform the generic modeling formats Having said that how you model a feature or set of features can also dramatically improve or hit the runtime performance whether or not you use IVE etc Gordon Tomlinson Product Manager 3d Technology Project Wyvern Overwatch(r) An Operating Unit of Textron Systems -Original Message- From: osg-users-boun...@lists.openscenegraph.org [mailto:osg-users-boun...@lists.openscenegraph.org] On Behalf Of Yong Wang Sent: Wednesday, April 14, 2010 10:39 AM To: OpenSceneGraph Users Subject: Re: [osg-users] 3D model fomat Hi, Gordon: Thanks a lot for your quick response, does that mean IVE provides better performance for runtime?

Subject: [osg-users] How to not show textures
Hi everyone,
I'm having a tough time preventing textures from showing in the scene.
I've tried the approach explained in the QuickStartGuide, but I'm
obviously missing something bigtime...
Here is the main part of the code:
Code:
unsigned int mode = osg::StateAttribute::OVERRIDE |
osg::StateAttribute::OFF;
osg::ref_ptr osg::StateSet state = sceneNoColor-getOrCreateStateSet();
for( unsigned int ii=0; ii 12; ii++)
{
state-setTextureMode( ii, GL_TEXTURE_1D, mode );
state-setTextureMode( ii, GL_TEXTURE_2D, mode );
state-setTextureMode( ii, GL_TEXTURE_3D, mode );
}
Frankly, I wouldn't mind removing the textures alltogether, but I'm not
sure how to do that efficiently.
I would very much appreciate any suggestions about how to make this
work.
Thank you in advance.
Inos

Hi all -- The OSG v2.8.3 final release has just been tagged. Congratulations and many thanks to everyone in the community who pitched in and helped me get this out the door. The community effort really caught a lot of issues that I would never have caught on my own, so again, thanks! It's hard to believe it's been 6 months since 2.8.2. The 2.8.3 release takes new functionality, long available on trunk and in developer releases, and makes those features available in a stable release for developers to use in production releases of their OSG-based apps. I don't have write access to the downloads page, so I've made a source ZIP available here, until it can be moved to the OSG server: http://www.skew-matrix.com/osg283/OpenSceneGraph-2.8.3.zip Robert, if you could move that, I'd appreciate it. Does anyone want to volunteer to build binaries? Preferably, someone who has done it in the past, so that the packages remain consistent from release to release. After the downloads page is in shape, I'll push the press release out to opengl.org and khronos.org. Use this URL to svn checkout the 2.8.3 final release tag: http://www.openscenegraph.org/svn/osg/OpenSceneGraph/tags/OpenSceneGraph -2.8.3 The release status page serves as the release notes: http://www.openscenegraph.org/projects/osg/wiki/Support/283release And the press release is still located here: http://www.openscenegraph.org/projects/osg/wiki/News/Press/OSG2.8.3 The only issue I'm aware of with 2.8.3 at this point is a problem I discovered with the 3DS exporter handling certain MatrixTransforms, possibly an issue with how the matrix decomposition handles corner-case matrices. The behavior is the same on svn trunk and not a show stopper in my opinion. I've exchanged offline emails with Sukender and supplied him with a reproducer .osg model.

Hi By default OSG will have display list turned on which means the drawing is cached and thus when you change something it will not be reflected, if your changing tings a lot you might want to disable display list alternatively you can tell OSG to rebuild the display list with a call like myGeometry-dirtyDisplayList(); I would recommend a searching the forum archive as well as this has been discuss many times and there are many ways in which you could edit geometry on the fly Gordon Tomlinson Product Manager 3d Technology Project Wyvern Overwatch(r) An Operating Unit of Textron Systems -Original Message- From: osg-users-boun...@lists.openscenegraph.org [mailto:osg-users-boun...@lists.openscenegraph.org] On Behalf Of David Cofer Sent: Friday, March 12, 2010 10:46 AM To: osg-users@lists.openscenegraph.org Subject: [osg-users] Moving a line and its vertices Hi, I have created a line in my scene based on the osggeometry example.

But when I run the simplest example, osgviewer with the cow.osg to render, it renders nothing and display warnings as TexGen::apply - not supported and some other stuff. I dug into the code and found that this is due that I disabled the OSG_GL_FIXED_FUNCTION_AVAILABLE. Does it mean that with OpenGL3 there is not fixed pipeline and all should be written by shaders? What about the projections of the objects from the 3D world to the camera plan, are they done by OpenGL or should I write them too?

R Fritz wrote: 1. Put your sun at the origin of world co-ordinates. 2. Put the planet at the origin. Make its axis of rotation the z axis. 3. Use a rotate transform to rotate it around its axis. (You've got this part.) 4. Translate the planet along the x axis, to its orbital radius. 5. Use a rotation around the z to position the planet in the x-y plane. (If the planet's orbit is not in the x-y plane, you will need more transformations.) These techniques are covered in most introductory computer graphics texts--that's where to go to learn about this kind of problem; studying software docs won't get you very far. I agree that you should try to familiarize yourself with the basics of computer graphics before asking the list about things like this. That said, I'll try to explain the relevant parts at a high level... Graphical 3D objects are composed of polygons, which are specified by their vertices (points in space). Each object is typically modeled relative to the origin of Euclidean space (0, 0, 0). In order to place an object somewhere else in space, or rotate it to a different orientation, you need to transform its vertices. This is done by multiplying each vertex by a 4x4 matrix (I won't get into why the matrix is 4x4, you can look that up :-) ). Transformation matrices can be set up to do translation (move vertices to another location relative to the origin), rotate, scale, and do other kinds of operations. You can also combine operations (a translate, followed by a rotate, for example), by simply multiplying the individual transformation matrices together. One more thing to realize is that each transformation essentially sets up a new, local coordinate system relative to the previously established system. When you translate an object, say along the X-axis first, then rotate it, you'll be rotating the translated coordinate system around the world's origin, so your object will effectively orbit the origin. Now, purists will argue that it's really the other way around, and the rotate is really happening first, followed by a translate along the new, rotated X-axis. It's all matter of perspective, though. Until you grasp the concepts (which might be a while, believe me), if you think you have the sequence right, but it's not working, just try reversing it, and that will usually fix it :-) In your case, you have two objects (a sun and a planet). The sun is easy to handle, just draw it exactly as its modeled. The planet needs a total of three operations, though. First you need to rotate the planet around its own axis, then you need to translate it away from the sun (about 93,000,000 miles should do :-) ), then you need to rotate it again to have it orbit the sun around it Now, in a scene graph like OSG, all transforms are applied as the graph is traversed from the root of the graph to the leaves, where the geometry lives. So, in order to draw the scene like you want, you'll need to attach the sun to the root of the scene (so it will be drawn at the origin), then you'll need to create your three transformations and attach them as children of each other, attaching the planet to the final transform. Like this: (root) / \ (sun) (orbit rotation \ (translation) \ (planet rotation) \ (planet) Now, I did this off the top of my head, so if it doesn't work, just try reversing the order, like I said above :-) --J ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.or g ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

That rendering is later composed on a 3D surface in order to be shown on the desktop. The graphics hardware video driver is no longer involved in GDI rendering, which means that mixing GDI and accelerated 3D rendering in the same window is likely to produce corruption like stale or blanked 3D rendering, trails, etc. Using Microsoft's OpenGL software rendering (the first item in the four OpenGL implementations) will achieve GDI compatibility, but at the expense of rendering speed and lack of modern features.

Re: [osg-users] How to avoid Z Fighting
How long is a piece of string, that's the sort of answer to your question.. The are a plethora of techniques you can used to try and mitigate the artifacts of z-fight and lack of precision in the z/depth buffer , a quick Google should throw up quite a lot, as this has been discussed adnosium on many graphics related, sites, lists and forums ( old Performer list, Vega, Creator,OpenGL etc and this list to name but a few) The problem with many techniques is that they are really view dependent, such that even a simple change in viewing distance or angle will cause the unwanted artifacts of z-fighting to appear, typically you need to apply more than one technique and in many cases change what your doing every time you change you viewing position. In the case of coplanar polygons using the polygon offset is one technique that can help at times (GL_POLYGON_OFFSET, glPolygonOffset(...)) Also factor such as the ratio between you far and near clipping planes affect the precision of the z-buffer, the distance from the origin etc Here's a useful link to Steve Bakers' Z-buffer calculate that illustrates how near and far clip planes and distance effect the precision http://www.sjbaker.org/steve/omniv/love_your_z_buffer.html Gordon Product Manager 3d __ Gordon Tomlinson Email : gtomlinson @ overwatch.textron.com __ -Original Message- From: osg-users-boun...@lists.openscenegraph.org [mailto:osg-users-boun...@lists.openscenegraph.org] On Behalf Of Robert Osfield Sent: Tuesday, October 20, 2009 3:55 AM To: osg-users@lists.openscenegraph.org Subject: Re: [osg-users] How to avoid Z Fighting Hi Miguel, The OSG will try to do it's best at optimizing the near/far planes out of the box, but it isn't a magic wand that solves all z fighting issues. There are a range of strategies that you can use to help avoid z fighting, from using depth partitioning (see the osgdepthpartion example) to tweaking your database to avoid issues.

Firstly your question is so open ended that your not going to get great help We handle the data but I'm unable to discuss what we do with it unfortunately If you do know the basics of OSG I would recommend you first learn that before proceeding (see the Quick start guide, you'll find a link on the OSG web site) Then it demands on what you want to do with the SAR data, has it been cleaned , processed, do you want to use this an imagery or as DEM, do you understand the SAR format, you will need to write an import tool to OSG to ingest either as imagery and or some form of elevation data, break the data in to manageable paging chunks etc.. There are many examples around they simply don't do it with SAR data just other data so you could use those as a basis for your own code Gordon Product Manager 3d __ Gordon Tomlinson Email : gtomlinson @ overwatch.textron.com __ From: osg-users-boun...@lists.openscenegraph.org [mailto:osg-users-boun...@lists.openscenegraph.org] On Behalf Of Benoît Poulard Sent: Wednesday, October 07, 2009 9:39 AM To: osg-users Subject: [osg-users] help to simulate SAR radar Hi, i need to make a SAR radar with OSG, and I don't know from where to begin.

Hi, I suppose you get many messages like this, so I apologise in advance. My scene is made of cubes and cylinders generated using ShapeDrawable. First I generate a large cell made of 1000 large cubes and up to 3000 cylinders and then a smaller cell made of the same number of elements, just smaller. Then I use osg::PositionAttitudeTransform to place several (16 to 64) of these smaller cells inside one of the cubes of the larger cell. Unfortunately this seems to cause the frame rate to drop to about 8 - 9, while the scene runs at about 120fps when section with the small cells goes out of the screen. I followed a suggestion I read on this forum and I tried to remove the use of osg::PositionAttitudeTransform and draw all the elements of the several smaller cells but this only makes the program take longer to load, but once it's loaded it still runs at about the same frame rate. I am just a beginner and I was wondering if any of you clever people can give me a pointer in the right direction or indicate some useful documents that my help me make this run a little faster.

Re: [osg-users] OSG Threading
One way Basically you need to create a message/data passing system between the GUI and the APP update thread that is thread safe. In the GUI thread when you want to add a request to be carried out in the APP you get a lock on the message queue you created ( generally I use a wait until lock required on the GUI side), then add your message or messages to the queue Then on the app side during the APP update I would attempt to get a lock on the queue ( in this case it would be a try and continue, so if you cannot get a lock just try again next frame), once you can get a lock you can consume the queues messages and take the action requested in the messages , (you might on service only N of Me messages if you have a lot.) and then release the queue once you have consumed the messages.

If an app was purely link with C lib its not an issues Most of the OSG 3rd party requirements are typically built with C++ so you need to ensure they are build with the same CRT and settings. Things like libJpeg, png, tiff, gdal, collada, xerces, proj4, libxml geos, boost etc While first time round it can take a little time to assemble your OSG 3rdparty sources and set them up, in the long run it is worth it ( at least for me ), for a commercial application I need to know that all the libraries I use meet the standard build requirments, and the only way to ensure that is to build them myself Gordon Product Manager 3d __ Gordon Tomlinson Email : gtomlinson @ overwatch.textron.com __ -Original Message- From: osg-users-boun...@lists.openscenegraph.org [mailto:osg-users-boun...@lists.openscenegraph.org] On Behalf Of Cory Riddell Sent: Tuesday, September 01, 2009 3:03 PM To: OpenSceneGraph Users Subject: Re: [osg-users] OT: do I need to recompile OSG? Hi Gordon, Tomlinson, Gordon wrote: Generally it is recommend you build every thing with the same compiler version ( it saves time in the long run ) I started out thinking this is the obvious answer, but the more I think about it, I'm not so sure. For example, OSG uses OpenGL from operating system libraries or libraries supplied by my video card maker. These may not even be compiled by a Microsoft compiler and there certainly isn't any way for me to recompile them. This makes me think that it doesn't really matter. I would like to understand what the problem is with mixing object files built against different versions of library files.
