Over Thanksgiving Break, I started getting good painterly results under 'controlled' situations. Spheres and other simple structures with very regular geometry work very well.
You can see the indentations from the bump map show up as brush strokes on the final image, which is awesome.
The next thing Professor Egert asked me for, since this demo is working off the same base code as Shelf-Life, was to plug this onto Shelf-Life. That was accomplished before the end of Christmas break, and will be the subject of my next post.
