If you want smooth interpolation of points, you could have a look at
Kochanek-Bartels or Catmull-Rom splines. Both use the Hermite
basis functions to do the actual interpolation; the tangent vectors
for each control point are aquired from the 4 control points that
make up a single curve-segment. I believe Dave Eberly wrote a paper
on them for use in keyframe interpolation. Can't remember what it's
