Hello everyone,
I read the mails to the topic, because I have a similar problem.
The problem is, that I have texture on the graphics card that I don't want
to copy back to the working memory.
Now I want to put this texture onto an Object in the scene.
I work with OpenSG 2.0 and I have to say I have not much knowledge about the
FBOViewport, or how the stuff with the TextureChunk should work.
I'm trying to use the getGLID() functions one of you mentioned, but I got
some problems with it.
My approach is to create the OSG::Geometry with any Texture with
OSG::Material and OSG::SimpleTexturedMaterial.
Then I want to get the GLID() of the Texture and change this on the GPU with
OpenGL commands.
But how can I get access to the GLID() from the SimpleTexturedMaterial?
I hope someone of you could help me with that issue.
Thanks,
Constantin Müller
