Adding real recursion to the mix (and not just basic shadow rays) gives the added benefit of effects like transmission and reflection. By building off our phong model, we were able to recursively reflect a ray up to a given cutoff depth and modify the final color with a "reflective" float between zero and one. Reflections is one area of 3D graphics where a ray traced model really excels. With just a few more lines of code we were able to get results like those shown in the picture.
