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.

Member Function Documentation

osg::Vec4 osgUtil::HighlightMapGenerator::compute_color ( const osg::Vec3 &  R ) const

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.
