Detailed Description

Utility to use shader for a visual model in OpenGL.

This class is used to implement shader into Sofa, for visual rendering or for special treatement that needs shader mechanism. The 3 kinds of shaders can be defined : vertex, triangle and fragment. Geometry shader is only available with Nvidia's >8 series and Ati's >2K series.
