Your GL code segment actually uses PBO's in it... :-) > Texture buffer objects can make about 2^27 texels accessible within a shader. > > And i belive i have to use bindable uniforms for PBO's to make the changed > data quite fast accessible within my shader? Might that be right? I don't know anything about this particular extension so can't comment. It looks like the new texture buffer extension is kinda equivalent to a GL_TEXTURE_1D so I'd be inclined towards suggestion that one would create a new subclass from osg::Texture for the new extension. Do you have to use PBO's with texture buffer? Or can you just pass the data directly as per normal textures?
