Object Graphics: Code available for rendering tubes? [message #14415]

I have a data set of n (x,y,z) vertices that describe a smooth
curve in 3D. I also have a n point 1d array of corresponding
colours for each vertex. While I can render this as a thick
coloured IDLgrPolyline, adding lights does not give a 3D effect.
Does anyone have OG code that can generate a wire frame tube
given the triplets describing the "backbone"? (This isn't as
easy as it first appears. For example, consider the issue of
minimizing torsion between neighbouring hoops comprised of
polygon circles.)

I would *really* like to see RSI start a clearing house for
reusable OG code akin to AVS's International AVS Centre.

Cheers,
Darran.
