Upon striking a surface, each ray will be absorbed, reflected or transmitted in accordance with the laws of optics. Programmed with a mathematical model of the behavior of light rays, the machines can re-create lighting effects of dizzying complexity. Caltech's Jim Kajiya, for example, has used ray tracing to show how ripples...
