OpenGL.GL.NV.texture_shader2

OpenGL extension NV.texture_shader2

This module customises the behaviour of the OpenGL.raw.GL.NV.texture_shader2 to provide a more Python-friendly API

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.
