[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() );

[osg-users] Handover textures to OSG from opengl/opencl

Hello, I'm trying to find an efficient way (without copying) to handover textures created in OpenGl (and later in OpenCl) to OSG. I need to control the creation and upload of textures to the GPU. Can you point me in the right direction? Thanks -- Read this topic online here:

Re: [osg-users] OSG Multi-threading questions

Hello again! :) Looks like I am having some multi-threading issues with my application but to be honest I am not sure what is going on. Initialy, I though that the problem had something to do with the fact I load my model in a separate thread and then I add it to the scene from the main thread

Re: [osg-users] [osgCompute] Experiences with osgCompute

Hi Jens, I finally have come around to check your new version. And I like it. Particularly the class that inherits from the new Computation class is a lot cleaner now. As for the geometry-offset problem. It would be nice if you would let it know how you tackled the problem. One last thing:

[osg-users] [osgCompute] Use an osgCuda::Texture2D in a shader

Hi, I'm working on the port of a OpenGL / Cuda application to OSG / osgCuda. (OSG 3.0.1 with osgCuda from trunk) One of our class use Cuda to compute a buffer and then : - copy this buffer to a texture buffer (using cudaMemcpy) - bind this texture to a texture unit (using glBindTexture) - use
