'''OpenGL extension SGIX.polynomial_ffd |
|
|
|
This module customises the behaviour of the |
|
OpenGL.raw.GL.SGIX.polynomial_ffd to provide a more |
|
Python-friendly API |
|
|
|
Overview (from the spec) |
|
|
|
This extension adds the capability to alter vertex coordinates, the |
|
corresponding normal coordinates, and texture coordinates based on a |
|
client-specified trivariate polynomial functions. These functions may be |
|
thought of as a warping of object/texture space (or, alternatively, as a |
|
warping of the object embedded in object/texture space). |
|
|
|
Deformations of space are used for a variety of modeling effects, including |
|
character animation. The deformation specified in this extension is one of |
|
a variety of mappings that have been proposed. |
|
|
|
Only 3D to 3D deformation are considered. We shall not consider |
|
homogeneous deformations. |
