Right, but it does take a lot of shortcuts, and a lot of unrealistic 
features...you have to know how to set up a realistic scene. Also, the 
end result is a nice-looking image, while in optics simulations you 
might want data like angle of incidence for an individual ray, total 
incident energy on an area of surface, light path length, etc.
