Detailed Description

This class computes distances to drawables and splits the scene if necessary.

This class traverses the scene, computes the distance to each visible drawable and splits up the scene if the latter are too far away (in the z direction) from each other.

The documentation for this class was generated from the following file:

include/OpenFrames/DistanceAccumulator.hpp
