<P>PROBLEM TO BE SOLVED: To provide an accurate method of computing a boundary of a modeled object by means of robust and generalized Boolean operators in consideration of the facts that the prior arts are too much sensitive with respect to rounding errors because usual polyhedral representations depend on numerical values, and that a state of the art polyhedron may produce self-intersections, thus making the result inconsistent according to the state of the art validity criterion. <P>SOLUTION: The invention is directed to a computer-implemented process for computing a closed triangulated polyhedral surface resulted from a first modeled object and a second modeled object in a computer-aided geometric design system. The first modeled object is modeled by a first closed triangulated polyhedral surface and the second modeled object is modeled by a second closed triangulated polyhedral surface. The process includes S30, S40, S60, S70, S80, S90, S100. <P>COPYRIGHT: (C)2012,JPO&INPIT |
