Ha, you said it your self; in 3D it is not a question of what you place when
but where, in PostScript it is the other way around. I afraid you'll get
very Dali/Picasso like postscript-files. You even have to mind the
part-dat-files and primitives, cos backs can become fronts in PS very easy...

Ha again! SVG is no Postscript. SVG is for screens while PS is for a
printers; you can do things on your computerscreen that you simple can't do
with PS-vector information...
Again I'm very exicted and can't wait to download the beat.
PS. When I tried to programm a converter myself I used POV to PS instead of
DAT to PS, POV uses some intresting methods (some even PS-like) in their files!
