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
protectedpure 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::HighlightMapGenerator, osgUtil::HalfWayMapGenerator, 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.
