Re: [osg-users] CompositeViewer context cleanup and missing textures
Hi J.P, I have done a lot more investigation in the context clean up issues and have checked in a provisional fix for the issues. Could you please do an svn update and then test against your own applications to see if things are fixed. The code I've just checked in still has lots of debug info in place, and I haven't completed all parts of the work, through this afternoon I'll work on cleaning it up, but right now it should in a good enough state to test out. Could you do this against your app and let me know how you get on.

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] 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.

Re: [osg-users] CompositeViewer context cleanup and missing textures
Hi J.P, I've modified the osgcamera example to have code path for testing a series viewers, with sharing models and reloading them for each viewer. I've written about it on the thread VBO's - lifetime.. I'm able to get GL errors when using VBO's, and with your test model with a straight osgViewer::Viewer app. Below is the output of of running with your test model. I get even more errors when I force the use of VBO's with --vbo. The VBO and Texture object pools are all implemented independantly, but they are pretty similar code paths so there is decent chance that if an error exists in one it may well be present in the other. What the error might be I have no clue yet...

Hi J.P. I've just changed USE_NEW_TEXTURE_POOL to 0 and then tested: osgcamera -r 3 earth_sphere_dt1.ive And it doesn't produce any errors and model always comes up with textures. So it does look like the new osgcamera test is sufficient for testing this particular bug.

[osg-users] CompositeViewer context cleanup and missing textures
Hi all, I've run into the classic missing textures problem when stopping and restarting a compositeviewer multiple times in the same app. From previous threads on this problem it seems to be context cleanup/GL object cleanup that does not get done properly, but I'm just using the normal CompositeViewer and not messing with contexts/windows/sceneviews myself, so I thought the cleanup would be handled correctly. Attached a very slightly modified compositeviewer example. All it does is create/destruct the compositeviewer 5 times. When the viewer is created for the second time, all my textures are gone (just run without any arguments). Can anyone confirm the missing textures? Any hints as to what else needs to be done to make sure everything is cleared/flushed correctly? thanks jp -- This message is subject to the CSIR's copyright terms and conditions, e-mail legal notice, and implemented Open Document Format (ODF) standard.

Re: [osg-users] CompositeViewer context cleanup and missing textures
Hi Robert, it seems to be something broken on context destruction with the new texture pool. The orphaned list does not seem to be cleared properly. A texture is used from the orphaned list even though the context it belonged to had been destroyed earlier. When libosg is compiled with #define USE_NEW_TEXTURE_POOL 1 commented out, the example works as expected. regards jp J.P. Delport wrote: Hi, Robert Osfield wrote: Hi J.P.

Re: [osg-users] CompositeViewer context cleanup and missing textures
Hi J.P., Can anyone confirm the missing textures? Any hints as to what else needs to be done to make sure everything is cleared/flushed correctly? We've been doing something similar to this for a while now and it's worked for us, what I'm wondering is whether the recent changes to texture buffering and such would have broken this (i.e. if something that needs to be cleaned up and was before now isn't). Our own app still uses OSG 2.6 so I wouldn't have seen this. I haven't had a chance to check your code yet, give me a few minutes and I'll check if there's anything amiss that I can see.

Re: [osg-users] CompositeViewer context cleanup and missing textures
Hi Frederic, Since we don't have direct access to the textures, we can't make the call to setUnRefImageDataAfterApply(). Would there be another way? You can run a visitor to get to the textures and turn this setting off. You can either make your own, or use osgUtil::Optimizer::TextureVisitor like this: osg::Node* node = osgDB::readNodeFile(...); osgUtil::Optimizer::TextureVisitor tv(true, false, false, false, false, false); node-accept(tv); (the arguments to TextureVisitor's constructor are changeAutoUnRef, valueAutoUnRef, and the rest all false so nothing else is changed.) Now, as for the modified CompositeViewer example, I tried it on Windows Vista and it simply crashes the first time I hit ESC or the X button. Strange, I tried it on Vista as well and I didn't have any problem. I notice you're using the stable version of OSG (osg55 = OSG 2.8, the current SVN trunk is at 62), so perhaps something was fixed that affects this, and it would not crash for you in a more recent version. Hope this helps, J-S -- __ Jean-Sebastien Guayjean-sebastien.g...@cm-labs.com http://www.cm-labs.com/ http://whitestar02.webhop.org/ ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Re: [osg-users] CompositeViewer context cleanup and missing textures
Hi Frederic, Some more fun in perspective! At least, I'll try the texture pool solution in the latest SVN build to see if it helps. I think that's what's most susceptible to work. Even stable releases can have bugs. So I really suspect that you're hitting a bug that's fixed in SVN. As I said, I run the example on Windows Vista without crashes (I tried multiple times without problems) and I run an nVidia card as well (9800GTX+) with semi-recent drivers.
