Re: [osg-users] Incremental Draw?

Thanks J-S, I had the same idea myself but unfortunately OpenGL drivers don't take thread or process priority into account. I made a simple test app that just renders thousands of quads, ran two instances simultaneously, set the process priority of one to high, and the priority of the other to

[osg-users] Cannot save osgText::Text when statically linking OSG

Hi all, When I save my scene to a file.osg, osgText::Text nodes are not saved into the file. This happens only when I statically link OSG to my application, when I use the DLLs everything is OK. So I suppose that the Plugins osgText is not being registered/linked to my app. I have tried to

Re: [osg-users] Dynamic Terrain

@Torben Yes, I want to do the modifications at runtime. It is mainly due to interaction of actors with the terrain causing deformations. My idea is also to modify the height value in the terrain grid and this height value will constantly be updated and rendered to show a sort of real-time

Hi, sorry that my answer took so long. I had a lot of other things to do the last weeks. I posted an issue at the OSG FLT export project issue page: http://code.google.com/p/osgfltexport/issues/detail?id=1 And I added my files to the submission page:

@Robert: I have read up on a bit of the techniques people have tries to use for this: From what I've read, this is the approach: Represent the terrain as Blocks. Blocks are the basic storage unit for data and are used to transfer data from the CPU to GPU for processing. The Blocks are made up

Re: [osg-users] Making sure I am completely freeing up OSG shader-related resources

I am not surprised this message has been left unanswered as it is not rocket science to release shader objects. It might be a bug, or at least a very unfortunate behavior, in the AMD Catalyst drivers, see: JVM won't die after shader compile

I'm attempting to call Thread::setProcessorAffinity() by doing the following: Code: mThread-setProcessorAffinity(cpuNum); In looking at this code, I'm seeing the affinity is only set by this call if the following condition is true: Code: if (pd-isRunning Thread::CurrentThread()==this)

Re: [osg-users] integrating tessellation shaders into osg

I can't test your code right now because the code I am currently using in a geometry shader is compiled incorrectly on my machine and I can't make it work! I have reported a bug to AMD that they are currently investigating. I will test the code in the future, I just don't exactly know when.

Hi Iñaki, You'll need to include both the osg plugin and the osgText plugin. What USE_OSGPLUGIN lines are you using right now? Robert. On Fri, Nov 19, 2010 at 10:13 AM, Iñaki García igar...@euve.org wrote: Hi all, When I save my scene to a file.osg, osgText::Text nodes are not saved into

Hi Sanat, I sounds a bit complicated to me. VPB generates a quad tree paged database for you, I would suggest for your source of terrain data use the TerrainTile that are loaded at runtime, and using the quad tree scene graph structure that paged in at runtime if you want to manage the level of

Thanks a lot for you replies! I tried to use the code but so far without success. At most I get a completely black image, but sometimes the SnapImageDrawcallback's operator() is never even called.. Here is my code. What exactly am I doing wrong here? class

Re: [osg-users] [osgPlugins] OpenFlight Export - MultiTexturing - wrong Texture Coordinates

Actually, it appears this model will not be suitable for the osgfltexport test suite, as the initial view is an edge-on polygon, so the image compare will succeed even if the polygon is drawn incorrectly. However, I've noted that the issue appears to be related to rendering a PrimitiveSet
