A small (at least in the context of this thread) nitpick: it's not the
per-pixel color computation that allows ray-tracing to produce
high-quality images. These days, graphics hardware also allows
"arbitrary" code to be run to compute the color of each pixel. The main
reason that ray-tracing looks better for some scenes is the ability to
easily incorporate multiple reflections/refractions into the per-pixel
