Path Smoothing Algorithm

Looking into spline calculation for path smoothing. Vasilios suggested in his lecture last semester to use Catmull-rom spline (which generate movement that pass through all points). Don’t kinda like what I imagine the end-result would look like much though. So I’m going back to the trusty bezier spline, which smooth-over all points but the start and the end.

Wikipedia happen to have an excellent graphic presentation of how to do that too, without having to read through all those maths n..n
