Hello, I have been experimenting with 3D Rails,
I wanted to generate an editor where you set some points
and the whole track is interpolated circular.
(http://img5.fotos-hochladen.net/uploads/3drailwypft4n8ge.jpg)
My greatest problem is detecting wether the track piece should be curved convex or concave.
Right now I have just set it to alternate between the two forms each trackpiece.
Did anyone made some experience on this subject yet?
Yes I think was Ian who did a Bezier Library , perhaps this lib can help you... I'm not sure where is (we have a lot of stuff here).
Sorry I think was Hemlos.
