this is not a problem as writing a parser for stl is really a simple
task... I have a simple library based on FLEX... could it helps ?

really ? sound great!
I'm just looking at NEF polyhedron as they are totally new for me.

actually efficenty is not a problem as I'm still experimenting with
STL... and I don't know exactly where I'm gone :-)
