Two processes to produce simulated imagery are contrasted. The first is a physical approach based on terrain board model scenes, illumination sources, and an electro-optical camera. The second method utilizes computer graphics to render a mathematical model of a scene. Examples of the same scene modeled physically and by computer graphics are compared with respect to their utility in portraying image quality characteristics.
