  L3P user primitive substitution
 
Awhile back, I persuaded Lars Hassing to add a feature to L3P. I wanted the ability to substutite POV language commands in the comments of a .DAT file that could be used in place of the DAT primitives when rendering through POV. This would allow (...) (24 years ago, 3-Dec-00, to lugnet.cad.ray)

WOW! Chuck (and Lars) These are great! I just rendered a test for myself( before I saw this post) and I can't get over how cool this is. Thank you, thank you, thank you! -Andy Lynch (...) (24 years ago, 4-Dec-00, to lugnet.cad.ray)
 
  Re: L3P user primitive substitution
 
(...) This is a very cool feature, for anyone 'rolling their own'. I'd definitely recommend it for including scanned/bitmap images (like printed tiles), as the POV-Ray versions will be far superior to an BMP2DAT2POV-Ray conversion. For official (...) (24 years ago, 4-Dec-00, to lugnet.cad.ray)

(...) Lutz Uhlman's LGEO library does just this with some exceptions. It is a high quality library of many of the parts from LDraw in POV-Ray. It has a slightly steeper learning curve as compared to using L3P but I would still recommend it to anyone (...) (24 years ago, 4-Dec-00, to lugnet.cad.ray)
 
  Re: L3P user primitive substitution
 
(...) The L3GO parts could be folded in using this method. (...) In general, the POV definitions are much smaller than the DAT counterparts, so the size increase is menimal. However, perhaps a set of files that could be downloaded seperately and (...) (24 years ago, 4-Dec-00, to lugnet.cad.ray)

(...) Only if you can find them. I'm not sure the POV-Ray port of L3G0 is still around... (...) OK. (...) If this separate set of files were straight POV-Ray code, they could be kept in a separate directory, and the translator/renderer could include (...) (24 years ago, 5-Dec-00, to lugnet.cad.ray)
