The problem is as the following image shows: I have the red points in an ordered list, including C and D. I need to find F and E. The problem is that not every point has to be on the curve (the curve does not need to pass through any point, except for start and end).

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).
