Well, my program does exactly this when it finds the correct winding of one
polygon.

Well, I remember this thread, where Leonardo said that it created such a
program: http://news.lugnet.com/cad/dev/?n=2919
It's a long and old thread, so, search for the word "green" two times to find
the section that I'm referring to.
Is this the program that you are talking about?
play well,
zanette.
PS: Steve, did you receive the primitives that I've sent to you?
PS2: Does anyone want to help me to test this program? The only requirements
are to know how to use the mytest6 in L3Lab and have patience. If you want to
help me, send a message to i.z@uol.com.br and I will send the program to you.

| Hi, I've created a simple web page with some examples of the output of my program. There you will find the remaining primitives that hadn't been certified yet and all the technic bricks certified with my program. (URL) Steve, could you put them at (...)
