A method and a computer system for modeling, in a virtual environment of a computer simulation, virtual contaminants in a scene to be rendered. A processing module, using a graphical user interface on a display device, is used for defining, in a model, a first additive zone of the scene over which a virtual contaminant is to be added, defining, in the model, 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 a memory module is used for storing the model, the model being made available through a storage module for rendering the virtual contaminants on the scene in the computer simulation. A preview mode is used for launching the computer simulation at a rate lower than the expected rate of the computer simulation.

System and method for modeling virtual contaminants

Method and computer system for performing a computer simulation in which virtual contaminants are rendered on a scene thereof. A model defining a virtual environment of the computer simulation is loaded into memory module. The virtual environment defines a first additive zone and a second subtractive zone with vector paths therewithin and being at least partially enclosed within the first additive zone. An image generator module is used for adding a virtual contaminant over the first additive zone, removing, at least partially, the virtual contaminant within the second subtractive zone along the paths in 2D leaving a remaining virtual contaminant in the first additive zone and rendering an image for display comprising the remaining virtual contaminant in the virtual environment using a visual texture of the virtual contaminant. At least one border is defined along the paths for allowing smooth visual transition with one or more neighboring images.

A method and a computer system for performing a computer simulation in which virtual contaminants are rendered on a rendered scene of the computer simulation. A memory module is sued for loading thereinto a 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. An image generator module is used for adding a virtual contaminant over the first additive zone, removing, at least partially, the virtual contaminant within the second subtractive zone leaving a remaining virtual contaminant in the first additive zone and rendering an image for display comprising the remaining virtual contaminant in the virtual environment using a visual texture of the virtual contaminant. The computer simulation may be a vehicle computer simulation.
