System and Method for Modeling Virtual Contaminants

摘要

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.

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; 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; storing the model into a memory module for subsequently rendering the virtual contaminants on the scene in the computer simulation; launching by the processor the computer simulation in a preview mode, wherein a field of view is defined for rendering images of the scene from a user's position within the computer simulation; in the preview mode, for a single image and considering the field of view, adding by the processor a virtual contaminant over the first additive zone; in the preview mode, for the single image and considering the field of view, removing by the processor, at least partially, the virtual contaminant within the second subtractive zone leaving a remaining virtual contaminant in the first additive zone; and in the preview mode, rendering by the processor, at a rate lower than the expected rate of the computer simulation, the single image for display comprising the remaining virtual contaminant in the virtual environment using a visual texture of the virtual contaminant for display on a display device.
