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()

◆ 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 ( )
