Member Function Documentation

bool osg::ShadowVolumeOccluder::computeOccluder	(	const NodePath &	nodePath,
		const ConvexPlanarOccluder &	occluder,
		CullStack &	cullStack,
		bool	createDrawables = false
	)

compute the shadow volume occluder.

bool osg::ShadowVolumeOccluder::contains

(

const BoundingBox &

bound

)

return true if the specified bounding box is contained entirely within this shadow occluder volume.

bool osg::ShadowVolumeOccluder::contains

(

const BoundingSphere &

bound

)

return true if the specified bounding sphere is contained entirely within this shadow occluder volume.

bool osg::ShadowVolumeOccluder::contains

(

const std::vector< Vec3 > &

vertices

)

return true if the specified vertex list is contained entirely within this shadow occluder volume.

const HoleList& osg::ShadowVolumeOccluder::getHoleList

(

)

const [inline]

return the const list of holes.

HoleList& osg::ShadowVolumeOccluder::getHoleList

(

)

[inline]

return the list of holes.

const NodePath& osg::ShadowVolumeOccluder::getNodePath

)

[inline]

const Polytope& osg::ShadowVolumeOccluder::getOccluder

(

)

const [inline]

return the const occluder polytope.

Polytope& osg::ShadowVolumeOccluder::getOccluder

(

)

[inline]

return the occluder polytope.

float osg::ShadowVolumeOccluder::getVolume

(

)

const [inline]

get the volume of the occluder minus its holes, in eye coords, the volume is normalized by dividing by the volume of the view frustum in eye coords.

bool osg::ShadowVolumeOccluder::matchProjectionMatrix

(

const osg::Matrix &

matrix

)

const [inline]

return true if the matrix passed in matches the projection matrix that this ShadowVolumeOccluder is associated with.

bool osg::ShadowVolumeOccluder::operator<

(

)

[inline]

void osg::ShadowVolumeOccluder::setNodePath

(

NodePath &

nodePath

)

[inline]

Set the NodePath which describes which node in the scene graph that this occluder is attached to.
