Member Function Documentation

virtual void osg::LogicOp::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::LogicOp::compare ( const StateAttribute sa) const [inline, virtual]

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

Implements osg::StateAttribute.

References COMPARE_StateAttribute_Parameter, and COMPARE_StateAttribute_Types.

virtual bool osg::LogicOp::getModeUsage ( StateAttribute::ModeUsage ) const [inline, virtual]

Return the modes associated with this StateAttribute.

Reimplemented from osg::StateAttribute.
