示例1: enter
/*
Aufruf dieser Funktion erfolgt bei Traversierung des Szenengraphen
mittels OpenSG-Funktion traverse().
Enthaelt ein Knoten verwertbare Geometrieinformation so tragen wir
Zeiger auf seine Geometrie (OpenSG-Strukturen) im array gla_meshInfo_
ein.
Nebenbei bestimmen wir für die Geometrie auch noch die World-Space-
Transformation (evtl. existiert eine OpenSG-Funktion um diese
Information zu erhalten, der Autor hat keine in der OpenSG-API
entdeckt).
