iOS Drawing R&D

It’s no grand feat in UI design, but I put together this simple app to showcase some R&D I did in line-drawing. Elastic asked me to research line-drawing for iOS, aiming for the kind of clarity and crispness and responsive viscosity of the line-drawing in the legendary Paper app by Fifty Three. It was my first dip into cocos2d and OpenGL.

The app has undo/redo features, different line thicknesses, and line colors. Through experimentation, I was able to implement a function that ‘plays back’ the sequence of your strokes, re-drawing the picture before your eyes. It was pretty cool.
