Ray tracing also makes parallelism easier, and for certain kinds of renders (e.g: spheres) can be as accurate as possible with less memory use. Do you have some example renderings of reflection techniques that look as good as ray tracing in complex scenery? For example, take a look at these renders: http://hof.povray.org/images/ChristmasBaubles.jpg http://hof.povray.org/images/ChristmasBaubles.jpg http://hof.povray.org/glasses.html http://hof.povray.org/glasses.html Do you think these methods of approximation could reach that kind of quality?
