Reconstructing B-patch Surfaces Using Inverse Loop Subdivision Scheme

摘要: B-patch surface is the main block to construct triangular B-spline surfaces and has many interesting properties of over a parametric domain. This paper proposes new method for reconstructing low-degree using inverse Loop subdivision scheme, along with geometric approximation algorithm. The obtained are B-patches domain almost cross through data points original meshes after several steps approximating. Comparing techniques use mesh as control polyhedron, our reconstructed degree reduces 2 i times inverse. accuracy result can be improved by adjusting location knot vectors in each step iterations. Some experimental results demonstrate efficacy proposed approach. Because most often employed CAGD, compression, engineering, virtual reality, this practical significance.
