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.

Definition at line 44 of file PolygonOffset.h.

inline

Definition at line 68 of file PolygonOffset.h.

static float osg::PolygonOffset::getFactorMultiplier ( )
static
virtual bool osg::PolygonOffset::getModeUsage ( StateAttribute::ModeUsage &  ) const
