Abstract: An example computer-implemented method for reducing a number of polygons in a polygon mesh model of an object determines one or more viewpoints, and, for each viewpoint of the one or more viewpoints, determines a respective first subset of polygons of the set of one or more polygons, the respective first subset of polygons being candidates for removal from the polygon mesh model. The method further determines a first intersection of the respective first subsets of polygons, and removes from the polygon mesh model at least some of the polygons in the first intersection. The method identifies candidates for removal from the polygon mesh model as those polygons of the set of one or more polygons which are non-visible in the computer simulation from the one or more viewpoints.

Abstract: Systems, methods, and computer program products for managing simulated environments are described. A simulated environment is accessed which represents a physical environment, and representations of objects are included, maintained, or removed in the simulated environment based on whether objects are represented in image data of the physical environment, and based on whether objects are occluded by other objects in the image data of the physical environment. Future occlusion can also be predicted based on motion paths of objects.
