-The year is 1983, and CG graphics researcher Roy Hall has just developed his own model, the Hall Shading Model, that builds on and improves Whitted's recursive raytracing technique.  Hall created the above image, which he named *The Gallery* for the SIGGRAPH 1983 art show.  His image showcases his improved shading model, including soft diffuse fall-off from the spotlights on the walls and carpet, color-tinted reflections from Metals (which improves on Whitted's technique), and a soft spotlight highlight on the large mirror (upper right side of mirror) that goes back further and further in the reflections of the mirror itself - a cool effect that simulates a fine layer of dust on the mirror's surface.  I was so intrigued by Hall's classic image that I decided to try and duplicate it.  I'm happy to report that I not only recreated Hall's beautiful scene, I was able to bring it into real time - 60 FPS in the browser, even on your cell phone! <br>
