Detailed Description

Contains all things that can be precomputed before a traversal of Boxtree's.

This is a helper class for Boxtree::check() only!

Warning:

Does not work if there is a scaling or shear in m!

Author:

Gabriel Zachmann, written 1997, re-implemented on OSG in May 2002.

Todo:

• Es ist nicht egal, in welches Koord.system transformiert wird! Man sollte das abhaengig von der Anzahl der Polygone machen.
• Evtl. kann man m_b auch einsparen.
