interpolate equally spaced points

I am trying to use python to interpolate but I am having some troubles. I have a given set of points in 3D space that form a curve. I do not know the analytic equation of the curve. I need to interpolate some points on that curve that are equally spaced on the curve. Does anyone have any suggestions? Thanks in advance!

What kind of interpolation best suits?

If linear is all that's required, you can use the formula...

a * (1 - m) + b * m

Where a is the start, b is the finish and m is the magnitude between the points between 0 and 1.

I wrote a tool where you can visualise different interpolation methods. Choose the one you prefer (note that some interpolate more than 2 points) and check the source code (should be simple enough to translate the JavaScript to Python) to see how it's accomplished.
