(...) Hi Kevin, Another possibility to investigate is to change the up vector in inverse proportion to the bezier curve change. That would mean it would twist less where there's a sharper bend, and would possibly end up looking more authentic. But (...) (18 years ago, 26-Nov-06, to lugnet.cad.dev)

I calculate the up vector for the start of segment, and the up vector for the end of segment. (...) (18 years ago, 26-Nov-06, to lugnet.cad.dev)

I've got up/side/front vector stuff working now, so that I can control the orientation of cross sections of electrical cables at the start of a segment defined by two constraints. My issue now is that I don't know how to force the twist so that the (...) (18 years ago, 24-Nov-06, to lugnet.cad.dev)

Hi, I've got a reworked version of LSynth with a major problem... I cannot figure out how to control the twist of the cross section. I use bezier curve to created the nicely curved set of points, and compress it by tossing out points until the angle (...) (18 years ago, 24-Nov-06, to lugnet.cad.dev)

A sincere thanks to all of you. Your comments made me go back over (again) my export code, and I found an error. Now it works as expected. I was getting funny rotations because I mis-ordered the elements of the transformation matrix, duh. Seems (...) (18 years ago, 20-Nov-06, to lugnet.cad.dev, FTX)

(...) That looks like a correct mapping to me. Unless I'm mistaken the red and orange are on the same sides in both pictures. The unwrapped boxes are definitely identical and unless you've moved them in one or the other the whole thing is right. Tim (18 years ago, 19-Nov-06, to lugnet.cad.dev, FTX)
