Detailed Description

This is the most simple cube map generator.

It performs a direct association between reflection vector and RGBA color (C = R).

Member Function Documentation

osg::Vec4 osgUtil::ReflectionMapGenerator::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.
