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::PolygonOffset::getModeUsage

(

)

const [inline, virtual]

Return the modes associated with this StateAttribute.

Reimplemented from osg::StateAttribute.

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.
