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.

virtual osg::PolygonOffset::~PolygonOffset ( ) [protected, virtual]

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 [inline, virtual]

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

Implements osg::StateAttribute.

float osg::PolygonOffset::getFactor ( ) const [inline]
static float osg::PolygonOffset::getFactorMultiplier ( ) [static]
virtual bool osg::PolygonOffset::getModeUsage ( StateAttribute::ModeUsage ) const [inline, virtual]

Return the modes associated with this StateAttribute.

Reimplemented from osg::StateAttribute.

References osg::StateAttribute::ModeUsage::usesMode().

void osg::PolygonOffset::setFactor ( float  factor) [inline]
static void osg::PolygonOffset::setFactorAndUnitsMultipliersUsingBestGuessForDriver ( ) [static]

Checks with the OpenGL driver to try and pick multiplier appropriate for the hardware.

note, requires a valid graphics context to be current.
