Computer-implemented method of computing, in a computer aided design system, of a boundary of a modeled object

摘要

The present invention relates to a computer-implemented method of computing. In one embodiment, computing a boundary of a modelled object in a computer aided design system, the method may include accessing data defining a modeled object as a simplicial m-complex. The method may further include projecting the simplicial m -complex in n, m≧n. The method also may include computing a polyhedral boundary of the modeled object as a polyhedral n−1-cycle in the projection of the simplicial complex. The polyhedral n−1-cycle may substantially border the projection of the simplicial complex. The present invention is further directed to a computer program product and a computerized system for performing the method of the invention.
