I’'m programming a vertex shader using GLSL.
I tried to acces a 3D texture in the vertex shader but I have a problem with which format texture I have to use.
I have read NVIDIA OpenGL 2.0 Support, at the item 184.108.40.206 the documents speaks about these formats: GL_RGBA_FLOAT32_ARB
Where are these items defined? I have download the last NVIDIA SDK, but these items aren’'t defined ??? Meaning which are the include files needed to use these formats…maybe is needed some extension wrapper like GLEW (we are using it…could it be outdated ?)
