3D mesh hill-climbing algorithm, using Processing, Hemesh, Python and the image compare command-line tool in ImageMagick. Given any image the mesh will self-iterate towards it, first by transforming shape, then mesh face colour. The sequence pictured above takes about 1 hour, these are just 16 stills from thousands of permutations that take place over that duration. The result is an entirely automated 3D printable colour object visually similar to the image provided.
