 | | User POV substitutions in L3P

After playing with Ldraw, The first thing I wanted to do was learn the file format and write a converter to POV. Then I found L3P, and was delighted. When I saw the minifigs with faceted heads, I investigated and learned about the triangle and quad (...) (25 years ago, 8-Mar-00, to lugnet.cad.ray)

(...) It sounds as a good idea since the parts/primitives libraries will need updates only when new l-cad updates are released. The current version of l3p allthough really good still needs regular updates to keep up with the growing parts libraries. (...) (25 years ago, 8-Mar-00, to lugnet.cad.ray)

(...) If it makes renderings better, POV files smaller, and doesn't take a lot of effort on my part, how could I not be interested? Please continue your efforts! --Bram Bram Lambrecht / o o \ BramL@juno.com ---...---oooo-----(_...o---...--- WWW: (...) (25 years ago, 8-Mar-00, to lugnet.cad.ray)
