Member Function Documentation

virtual void osg::Fog::apply State   state const [virtual]
 

apply the OpenGL state attributes.

The global state for the current OpenGL context is passed in to allow the StateAttribute to obtain details on the the current context and state.

Implements osg::StateAttribute.

virtual int osg::Fog::compare const StateAttribute   sa const [inline, virtual]
 

return -1 if *this < *rhs, 0 if *this==*rhs, 1 if *this>*rhs.

Implements osg::StateAttribute.

virtual void osg::Fog::getAssociatedModes std::vector< GLMode > &    modes const [inline, virtual]
 

return the modes associated with this StateSet
