(a) Computing rays to cast, (b) calculating surface normals, (c) shading computations, (d) intersections, or (e) texture mapping.
If there are p pixels, n objects, and l lights, ignoring reflections or transparency, the
operations above will execute approximately (a) p+pl, (b) p, (c) p, (d) pn+pnl, (e) p
intersections are the most expensive.
