    Just so that the next person can avoid having to do the wikipedia-math-formula-to-Swift conversion, here’s a simple Catmull-Rom interpolation method for linear y=x data. I’m using it to create simple ski jump hill profiles for a possibly upcoming game, it’s so easy to describe a hill profile by just giving it control points and let…
