Detailed Description

Compute shading tables for encoded normals.

vtkEncodedGradientShader computes shading tables for encoded normals that indicates the amount of diffuse and specular illumination that is received from all light sources at a surface location with that normal. For diffuse illumination this is accurate, but for specular illumination it is approximate for perspective projections since the center view direction is always used as the view direction. Since the shading table is dependent on the volume (for the transformation that must be applied to the normals to put them into world coordinates) there is a shading table per volume. This is necessary because multiple volumes can share a volume mapper.
