Not using the tessellation that can be done in SDL, then?

How would that handle parts that are obscured by itself or other objects?

Interesting, thanks for explaining in a way I can understand.

We are here to serve. :-)

Yes of course. A lathe is a turning machine.

You know the drill. ;-)

A manual metal turning lathe would be over complicated IMO.
And where is the fun in pushing a button to get your shape.
Have you thought about the Kinect as an i/p device?
