Drawing Smooth Curves - Methods Needed

Question

How do you smooth a set of points in an iOS drawing app WHILE MOVING? I have tried UIBezierpaths but all I get are jagged ends where they intersect, when I just shift the po

Answer 1

I tried all of the above, but can't make it work. One of the answer yield a broken result for me even. Upon searching more I found this: https://github.com/sam-keene/uiBezierPath-hermite-curve. I did not write this code, but I implemented it and it works really really well. Just copy the UIBezierPath+Interpolation.m/h and CGPointExtension.m/h. Then you use it like this:

UIBezierPath *path = [UIBezierPath interpolateCGPointsWithHermite:arrayPoints closed:YES];

It is really a robust and neat solution overall.
