◆ getDistanceFromEyePoint()

virtual float osg::CollectOccludersVisitor::getDistanceFromEyePoint ( const Vec3 ,
bool   
) const
virtual

Get the distance of a point from the eye point, distance value in the eye coordinate system.

Note, not all NodeVisitor implement this method, it is mainly cull visitors which will implement. If the getDistanceFromEyePoint(pos) is not implemented than a default value of 0.0 is returned.

Reimplemented from osg::NodeVisitor.

◆ getDistanceToEyePoint()

virtual float osg::CollectOccludersVisitor::getDistanceToEyePoint ( const Vec3 ,
bool   
) const
virtual

Get the distance from a point to the eye point, distance value in local coordinate system.

Note, not all NodeVisitor implement this method, it is mainly cull visitors which will implement. If the getDistanceFromEyePoint(pos) is not implemented then a default value of 0.0 is returned.

Reimplemented from osg::NodeVisitor.

◆ getDistanceToViewPoint()

virtual float osg::CollectOccludersVisitor::getDistanceToViewPoint ( const Vec3 ,
bool   
) const
virtual

Get the distance from a point to the view point, distance value in local coordinate system.

Note, not all NodeVisitor implement this method, it is mainly cull visitors which will implement. If the getDistanceToViewPoint(pos) is not implemented then a default value of 0.0 is returned.

◆ removeOccludedOccluders()

void osg::CollectOccludersVisitor::removeOccludedOccluders ( )

Removes occluded occluders for the collected occluders list, then discards all but MaximumNumberOfActiveOccluders of occluders, discarding the occluders with the lowest shadow occluder volume.

◆ reset()

virtual void osg::CollectOccludersVisitor::reset ( )
virtual

Method to call to reset visitor.

Useful if your visitor accumulates state during a traversal, and you plan to reuse the visitor. To flush that state for the next traversal: call reset() prior to each traversal.

Reimplemented from osg::NodeVisitor.

◆ setMaximumNumberOfActiveOccluders()

void osg::CollectOccludersVisitor::setMaximumNumberOfActiveOccluders ( unsigned int  num)
inline

Sets the maximum number of occluders to have active for culling purposes.

◆ setMinimumShadowOccluderVolume()

void osg::CollectOccludersVisitor::setMinimumShadowOccluderVolume ( float  vol)
inline

Sets the minimum shadow occluder volume that an active occluder must have.

vol is units relative the clip space volume where 1.0 is the whole clip space.
