Detailed Description

This is the base class for cube map generators.

It exposes the necessary interface to access the six generated images; descendants should only override the compute_color() method.

Member Function Documentation

virtual osg::Vec4 osgUtil::CubeMapGenerator::compute_color (  const osg::Vec3 &  R  )  const [protected, pure virtual]

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. Implemented in osgUtil::HalfWayMapGenerator, osgUtil::HighlightMapGenerator, and osgUtil::ReflectionMapGenerator.

void osgUtil::CubeMapGenerator::generateMap (  bool  use_osg_system = true  )

Generate the six cube images. If use_osg_system is true, then the OSG's coordinate system is used instead of the default OpenGL one.
