Evenly distribute points along a path I have a user defined path which a user has hand drawn - the distance between the points which make up the path is likely to be variant.
I would like to find a set of points along this path which are equally separated.
Any ideas how to do this?

You're looking for an arc-length parametrization that you can sample uniformly. See http://groups.google.com/group/comp.graphics.algorithms/msg/c7025fd53b18db94 .
You probably need to smooth the input data before doing this. See for instance Efficient Curve Fitting. See also a summary.
