| | Updated Axle and Connect POV primitives

I updated the axle and connect primitve POV file. I also added POV code to the axlehole and connect primitves so that L3P add my code automatically. I put these in a zip file that just needs to be put into the /P directory. let me know if these are (...) (22 years ago, 1-Feb-03, to lugnet.cad.ray, lugnet.cad.dev)

A long time ago, I started building little robots that were roughly minifig size. I built this particular robot at least 6 years ago, and I've always loved it. I recently decided to ldraw it and test out a new idea for "instructions". Here is the (...) (22 years ago, 31-Jan-03, to lugnet.space, lugnet.cad.ray)

Got it! Actually, it wasn't the L3P colors, it was the color inc file Jeroen mailed me. He found the bug and mailed me a fix (which I fwd'ed to you and the others I have send this file to). I looked at the file on my spare computer, and there it (...) (22 years ago, 29-Jan-03, to lugnet.cad.ray)

You are probably going to kick yourself for this one. You're right about the color white, but it has to do with how you defined it. The rgb had one too many values: rgb <0.975, 0.975, 0, 900> instead of: rgb <0.975, 0.975, 0> :) Thanks for the (...) (22 years ago, 29-Jan-03, to lugnet.cad.ray)

Ok, so I figured something out. It's not the model I'm rendering or the radiosity settings that are taking forever, POV is hanging on _one_ part. A 1x2x3 panel. It was clear in my first attempt, so I changed it to white (Color15). Still hangs on (...) (22 years ago, 29-Jan-03, to lugnet.cad.ray)

I believe you are currently out of luck. The way radiosity is currently set up in POV-Ray 3.5, multiple passes are required. That may or may not change in future versions, but I'm not going to hold my breath. I have a 450 MHz so I understand your (...) (22 years ago, 28-Jan-03, to lugnet.cad.ray)
