Abstract
A system and method for providing positional error correction for particles of destructible objects in a three-dimensional volume in a virtual space includes electronic storage to store center-of-mass information of a set of objects, using a high-precision floating point format. Prior to runtime and/or interactive manipulation of the set of objects, a texture map is generated that includes positional information in a floating point format having less precision than the high-precision floating point format. A simulation uses this texture map to determine simulated center-of-mass information of the set of objects. This simulated center-of-mass information is compared with the previously stored center-of-mass information to determine which objects have positional errors, and which offsets are needed to correct the positional errors. The stored center-of-mass information is adjusted by the determined offsets, such that subsequent use, during interactive runtime, has no or reduced positional errors and/or artifacts caused by positional errors.
