This experimental iOS Graphics app is ½ old-school 2D pixel editor and ½ 3D global illumination renderer. I developed a ray casting algorithm that uses low- resolution depth and color maps to produce a high resolution rendering with subtle lighting and shading.
From left to right: depth map (user created), color map (user created), depth + color (used for final render), global illumination rendering.
Design progressed through several prototypes and my algorithm was ported to the iPhone GPU by a contractor before setting this project aside to work on Percolator 2.0.

The 'bitmap rendering' technique was originally developed for an experimental Rogue-style game in 2003.
