"WebFirst, we assign a parameter value t i to each point P i. The usual way to do this is to use chord-lengths -- you choose the t i values such that t i − t i − 1 = ‖ P i − P i − 1 ‖. Then you compute x as a function of t. The calculation is the one you already know, but it's just x = f ( t) instead of y = f ( x). " - Cubic hermite splines
