'''OpenGL extension ATI.vertex_streams |
|
|
|
This module customises the behaviour of the |
|
OpenGL.raw.GL.ATI.vertex_streams to provide a more |
|
Python-friendly API |
|
|
|
Overview (from the spec) |
|
|
|
This extension adds the ability to handle sets of auxilliary |
|
vertex and normal coordinates. These sets of auxilliary |
|
coordinates are termed streams, and can be routed selectively |
|
into the blend stages provided by the vertex blending extension. |
|
This functionality enables software animation techniques such |
|
as keyframe vertex morphing. |
|
