Here's the same picture as before, with one important difference: the spheres look, well, spherical. Between dancing under the stars (and early-morning fog!) and class, I've somehow managed to find both the time and requisite sanity to implement Phong shading. Given libraries for vector operations, this is a relatively trivial task; nevertheless, it adds a whole new dimension (yeah, I couldn't resist) to rendered images. I'm also computing shadow rays to get the nice (albeit somewhat pixelated) shadows on the occluded parts of spheres. Next up: box and mesh intersections, supersampling, and hierarchical rendering. I'll keep posting progress images as I go along.
