Hi I have some time to spend on my .dat to .ps program. It is going well and I will publish at the end of August a beta version. Meanwhile, I have to optimize the program. Are there special request, maybe that I can implement them in time.... Guido (23 years ago, 3-Aug-01, to lugnet.cad)

Wow, it's been a while Guido! But I am sure happy to hear from you. I wish you luck with the program and I am looking forward to seeing it. Right now, I do not have any special requests, I only hope that the PS format you are generating will import (...) (23 years ago, 3-Aug-01, to lugnet.cad)

(...) Hi Guido, I thought about doing that to, but converting 3D data in to 2D was a bit above my head, so I'm very curious how you gonna do that! Also, how you gonna fix the transparant part problem? cos I know that transparancy and PostScript (...) (23 years ago, 3-Aug-01, to lugnet.cad)

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)

(...) 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)

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)

Don: (...) Looks good, but I think it would be useful to reduce the file to the visible surfaces before saving it. Jacob (23 years ago, 7-Aug-01, to lugnet.cad.dev)

(...) 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)
