  Re: Postscript converter
 
Jeroen: (...) That's the easy part (sort of). You just multiply all points with an apropriate rotation matrix and ignores one coordinate. (okay - and then there is a lot of "what's on top" questions) (...) The only solution I have been able to come (...) (23 years ago, 5-Aug-01, to lugnet.cad, lugnet.cad.dev)
 
  Re: Postscript converter
 
(...) 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 (...) (23 years ago, 6-Aug-01, to lugnet.cad.dev)
 
  Re: Postscript converter
 
Hey, with all this talk about PostScript converters I wonder if anyone would like to take a shot at completing the EPS output in ldglite? I started it once upon a time using the opengl feedback buffer to produce the transformed geometry. However the (...) (23 years ago, 6-Aug-01, to lugnet.cad.dev)

Hmmm. Looks odd, but it is something Photoshop could not parse it as an EPS (Generic nor Photoshop) Freehand or Illustrator did not create the picture. Acrobat distiller however created a PDF file of which I posted a picture at (URL) and a good (...) (23 years ago, 7-Aug-01, to lugnet.cad.dev)

  Re: Postscript converter
 
(...) Yes, that's where I got stuck. If anyone knows a nice occlusion algorithm that solves this problem in vector space (without converting to raster) I could probably also use it to speed up the rest of ldglite as well. I'm hoping for an (...) (23 years ago, 9-Aug-01, to lugnet.cad.dev)

Don: (...) There is a quite useful algorithm in my big computer graphics book. It is from 1991 (or before) and I think the title simply is "Computer Graphics". The algorithm is called "space-partitioning tree" or something like that. Jacob (23 years ago, 10-Aug-01, to lugnet.cad.dev)
