Detailed Description

PolygonOffset - encapsulates the OpenGL glPolygonOffset state.

Constructor & Destructor Documentation

osg::PolygonOffset::PolygonOffset ( )

osg::PolygonOffset::PolygonOffset ( float factor,

float units

)

osg::PolygonOffset::PolygonOffset ( const PolygonOffset & po,

const CopyOp & copyop = CopyOp::SHALLOW_COPY

) [inline]

Copy constructor using CopyOp to manage deep vs shallow copy.

Member Function Documentation

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

return -1 if *this < *rhs, 0 if *this==*rhs, 1 if *this>*rhs.
Implements osg::StateAttribute.

float osg::PolygonOffset::getFactor ( ) const [inline]

virtual bool osg::PolygonOffset::getModeUsage ( ModeUsage & usage ) const [inline, virtual]

Return the modes associated with this StateAttribute.
Reimplemented from osg::StateAttribute.
