Claim Text:
1. A method for modeling, in a virtual environment of a computer simulation, virtual contaminants in a scene to be rendered comprising: in a model, defining by a processor a first additive zone of the scene over which a virtual contaminant is to be added, the first additive zone comprising therewithin a plurality of additive polygons to allow production of a virtual contaminant image mask therefor, the plurality of additive polygons comprising: in the model, defining by the processor a second subtractive zone of the scene over which the virtual contaminant is to be at least partially removed, the second subtractive zone being at least partially enclosed within the first additive zone; and storing the model into a memory module for subsequently rendering the virtual contaminants on the scene in the computer simulation.
