No. There are a lot of calculus, and postscript need time...

We have few ways to try. But it will be difficult to improved with
only postscript.

With next version, it will be possible to write extern file. So you'll
could have some results faster (for ex-chaine_olympique, you have
actually 5 times the calcul of torus and 3 times the calcul of rotation).

An other problem is to sort faces. It takes a very, very long time
with postscript.
