PROCESSING OF GEOMETRIC DATA WITH ISOTOPIC APPROXIMATION WITHIN A TOLERANCE VOLUME

摘要

The processing of geometric data starts with a tolerance volume Ω that is related to raw geometric starting data. A canonical triangulation is initiated (201) in the tolerance volume, on the basis of a set S of sample points taken at the limits of this tolerance volume, and points LBB located on the exterior thereof. This canonical triangulation is refined (203) until the sample points have been classified, thereby obtaining a dense mesh of the tolerance volume. This dense mesh is then simplified (207) via triangulation modification operations, while preserving the topology and classification of the sample points.
