I'm writing a racetrack editor and have a pretty funky interface where you can design your track with anchor points which define hermite splines which is easy to use and looks great.

All these dots are defined in a array. Has anyone got a useful routine that will convert these anchor point data to a 3d mesh. I've looked at addvertex comands but got in a bit of a state.

This will be released to the community with source when i'm done.
