iPhone smooth sketch drawing algorithm
I’m looking for an actual demonstrable example of code or an algorithm responsible for super smooth beautiful paint strokes like those found in the Penultimate app?
Heck, any code that demonstrates any smooth paint stroke based upon a user’s finger stroke would be great. The elusive nugget I’m seeking is “smooth”. Other answers on SO attempt to address smooth stroke drawing, however none target Penultimate as the elusive goal, and none of the solutions achieve anything as smooth and refined as Penultimate, which is what this question is after specifically, not just general smoothing algorithms.
This has been discussed a few times. You need to use bezair curves and OpenGL. I don’t want to rewrite it all, so here is a link to an answer I posted a while ago on the same topic. It is a rather robust answer and should help you get in the right direction.
