'''OpenGL extension ARB.fragment_shader |
|
|
|
|
|
This module customises the behaviour of the |
|
|
OpenGL.raw.GL.ARB.fragment_shader to provide a more |
|
|
Python-friendly API |
|
|
|
|
|
Overview (from the spec) |
|
|
|
|
|
This extension adds functionality to define fragment shader objects. A |
|
|
fragment shader object is a shader object (see the ARB_shader_objects |
|
|
extension) that, when attached to a program object, can be compiled and |
|
|
linked to produce an executable that runs on the fragment processor in |
|
|
OpenGL. The fragment processor is a programmable unit that replaces the |
|
|
OpenGL 1.4 fixed-function texturing, color sum and fog stages. This |
|
|
extension also defines how such an executable interacts with the fixed |
|
|
functionality fragment processing of OpenGL 1.4. The language used to |
|
|
write fragment shaders is not discussed here. That language is defined |
|
|
in the OpenGL Shading Language specification as the Fragment Shading |
|
|
Language. |
