you can use the PrimitiveIterator to get all the primitives of the
geometry. The downside of course is that you'll have a hard time
avoiding duplication of vertices on edges of the source geometry. I
suppose you'd need a half edge structure to get this right -- there is
HalfEdgeGraph in OpenSG, but AFAIK it is only targeted at the geometry
striper, so I'm not sure if it helps.
Cheers,
Carsten
