A method and apparatus for reproducing real-world lighting effects in a computer animated object, in which a three dimensional virtual set is created in proportion to the physical set, optical parameters of each physical light source used on the real-world set are input into the model and qualified by effects such as dimming, filtration, diffusion, occlusion and attenuation to produce synthetic lighting of the virtual set. The camera lens transmission characteristics and film speed may also be incorporated into the virtual set parameters. The three dimensional computer animated object is positioned and oriented within the virtual set according to the position and orientation in which the visual effect is to appear in the cinematographic scene, and is thus synthetically illuminated within the virtual set in exactly the manner that a physical object of the same shape in the physical set would be illuminated, to produce a computer animated object that exhibits lighting effects as would appear in a comparable physical object photographed through the same camera lens using the same film as used in the physical set. The invention thus eliminates most of the judgment required on the part of a visual effects artist trying to reproduce in a computer animated object the lighting effects used in a cinematographic scene, and thus significantly reduces the time required to integrate the visual effect object into the cinematographic scene. Inherent characteristics of many light sources, filters, cameras and films can be maintained in a database or look-up table and can thus be entered into the virtual set by reference to the actual light sources and camera used on the real-world set.
