Detailed Description

This cube map generator produces a specular highlight map.

The vector-color association is: C = (R dot (-L)) ^ n, where C is the resulting color, R is the reflection vector, L is the light direction and n is the specular exponent.

Override this method to define how colors are computed.

The parameter R is the reflection vector, pointing from the center of the cube. The return value should be the RGBA color associated with that reflection ray.

Implements osgUtil::CubeMapGenerator.
