CSG, boolean operations nodes...

[Jarek Rzepecki <jarekr@xxxxxxxx>]

Hi!
  I need a boolean operations on objects in OpenInventor. I know that OI
himself doesn't support them... Hovever i have found on the web paper
"Interactive Rendering of CSG Models" 1996 by Tim Wiegand. In this paper
author have mentioned that he has written some Inventor nodes... Could
sombody send me those nodes (source of course) or tell me where can i find
them? I have tried to conntact Tim Wiegand but i can't find his current
e-mail adress... I have also checked the
www.arct.ac.uk/research/cadlib/inventor web page. Those nodes should be
there but they aren't ("no such file" - error while downloading...) 
Thank you...
