Detailed Description

This cube map generator produces an Half-way vector map, useful for hardware-based specular lighting effects.

It computes: C = normalize(R - L), where C is the resulting color, R is the reflection vector and L is the light direction.

◆ compute_color()

inlineprotectedvirtual

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.
