I would use l3p and povray, but since l3p only runs on wintel, you have to do that part on a wintel box. Here's how I would do it: 1. Make a batch file to create a dat file for each part. 2. make a batch file to run l3p on each of those dat files 3. (...) (25 years ago, 27-Nov-99, to lugnet.db.brictionary, lugnet.cad)
