Constructor & Destructor Documentation

osg::Fog::Fog ( )
osg::Fog::Fog ( const Fog fog,
const CopyOp copyop = CopyOp::SHALLOW_COPY 
) [inline]

Copy constructor using CopyOp to manage deep vs shallow copy.

virtual osg::Fog::~Fog ( ) [protected, virtual]

Member Function Documentation

virtual void osg::Fog::apply ( State ) const [virtual]

apply the OpenGL state attributes.

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

Reimplemented from 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 bool osg::Fog::getModeUsage ( StateAttribute::ModeUsage ) const [inline, virtual]

Return the modes associated with this StateAttribute.
