Splines

[Todd D. Ellner]

I'm writing an extension to Fractal Design's exceedingly
useful Poser program. When I'm done it will animate the
figures. The design problem I am having right now is one
that you folks might be able to help me on.

Linear interpolation is no good, so I am looking at a spline-
based routine. Would you people find it more useful to
have NURBS or Rational Non-uniform B-splines at the
heart of the thing?

Thanks in advance,
Todd
