- '''OpenGL extension NV.texture_shader2
-
- Overview (from the spec)
-
- This extension extends the NV_texture_shader functionality to
- support texture shader operations for 3D textures.
-
- See the NV_texture_shader extension for information about the
- texture shader operational model.
-
- The two new texture shader operations are:
-
- <conventional textures>
-
- 22. TEXTURE_3D - Accesses a 3D texture via (s/q,t/q,r/q).
-
- <dot product textures>
-
- 23. DOT_PRODUCT_TEXTURE_3D_NV - When preceded by two DOT_PRODUCT_NV
- programs in the previous two texture shader stages, computes a
- third similar dot product and composes the three dot products
- into (s,t,r) texture coordinate set to access a 3D non-projective
- texture.
-
- The official definition of this extension is available here:
- http://oss.sgi.com/projects/ogl-sample/registry/NV/texture_shader2.txt
