조정 메쉬의 각진 모서리를 유지하기 위한 수정 Doo-Sabin 곡면 분할 알고리듬 개발

초록

Recently, designing 3D objects using various modeling techniques become getting more important issues in related industrial fields. The subdivision scheme is a technique that generates a smooth surface through many times of refinement processes that split polygons of control mesh into several smaller polygons. In this paper, we propose a new subdivision algorithm that preserves sharp-edges of control mesh after several refinement processes in the Doo-Sabin subdivision scheme. Using the proposed algorithm, the Doo-Sabin subdivision scheme can be well applied to modeling 3D objects with sharp-edges.
