Claim Text:
1. A method for rendering virtual contaminants on a rendered scene in a computer simulation comprising: reading, by a processor, a model from a database, the model defining a virtual environment of the computer simulation, the virtual environment defining a plurality of zones comprising a first additive zone and a second subtractive zone, the second subtractive zone being at least partially enclosed within the first additive zone, the virtual environment defining a plurality of additive polygons within the first additive zone; adding, during the computer simulation by an image generator module having one or more dedicated graphical processing units, a virtual contaminant over the first additive zone using a maximum mathematical operation on the plurality of additive polygons to obtain a virtual contaminant image mask for the first additive zone; removing by the one or more dedicated graphical processing units during the computer simulation, at least partially, the virtual contaminant within the second subtractive zone leaving a remaining virtual contaminant in the first additive zone; and rendering, by the one or more dedicated graphical processing units, an image for display comprising the remaining virtual contaminant in the virtual environment using a visual texture of the virtual contaminant.
