Arc Length

I had to compute the length of arcs of Earth's meridian. I noticed that there was no analytical solution for this so I wrote this very simple function.It computes the arc length of an ellipse centered on (0,0) with radius a (along OX) and radius b (along OY)x(t) = a.cos(t)y(t) = b.sin(t)with...

I've seen many people ask for a way to find the closest point on a curve from some given point in space. If the curve is a piecewise linear one, this is not too difficult, since this reduces to finding the closest point on a line segment, and then testing each line segment. (With care, you need...
