Member Function Documentation

virtual void osg::PolygonOffset::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.

static bool osg::PolygonOffset::areFactorAndUnitsMultipliersSet ( )
static
virtual int osg::PolygonOffset::compare ( const StateAttribute sa) const
inlinevirtual

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

Implements osg::StateAttribute.

Return the modes associated with this StateAttribute.

Reimplemented from osg::StateAttribute.
