Point-Sampled Surface Simulation Based on Mass-Spring System

摘要

In this paper, a physically based simulation model for point-sampled surface is proposed based on mass-spring system. First, a Delaunay based simplification algorithm is applied to the original point-sampled surface to produce the simplified point-sampled surface. Then the mass-spring system for the simplified point-sampled surface is constructed by using tangent planes to address the lack of connectivity information. Finally, the deformed point-sampled surface is obtained by transferring the deformation of the simplified point-sampled surface. Experiments on both open and closed point-sampled surfaces illustrate the validity of the proposed method.
