(...) While I agree with both of you, we should keep in mind that Orion said that this is a postnuke problem. Since the whole site is done with postnuke, I don't think there's much he can do about it, unless there's some postnuke option to work (...) (20 years ago, 6-Dec-05, to lugnet.cad.dev.org.ldraw)

(...) Thanks for the offer. It sounds like I can make use of parameters that Lars has already implemented if I just change my outputs slightly, so I think I'll go that route. If you've already got the code or pseudo-code lying around, I'd like to (...) (20 years ago, 6-Dec-05, to lugnet.cad.ray)

(...) I can do that. Unless I'm badly mistaken, my existing up will work fine as a sky vector. (...) Reading between the lines of the descriptions of the various camera settings, it really looks like POV-Ray automatically generates direction, up, (...) (20 years ago, 6-Dec-05, to lugnet.cad.ray)

(...) Slashdot had a link to an article about that vehicle, too, but it requires a specially-shaped surface to work. The one with the rotating weight works on a flat surface. (20 years ago, 6-Dec-05, to lugnet.technic, lugnet.robotics)

Well, I think I've tried to explain what I need to do 3-4 times already, which is where I think the language barriers have played a pretty big role... The reason I tried to cook the problem down, is to reduce confusion, but I guess that was a bad (...) (20 years ago, 6-Dec-05, to lugnet.cad, FTX)

You're onto something with the split in the chassis, though, and I thought of a three-wheeled version, where the front single wheel can pivot, like on a tricycle. I found this (...)
