Research on the parameterization and remeshing technique application in surface reconstruction

摘要

In order to solve the problems that complex mesh needs a huge storage and high transmission price, and is difficult to be edited, simple algorithms are often required to obtain a series of object simulations. In this paper, three different parameterization algorithms are adopted to analyze their different effects on mesh quality after remeshing. Based on the parameterized mesh over a planar domain, subdivision algorithm is used to transform the mesh with arbitrary structure to a regular triangular or quadrilateral mesh. The algorithm in this paper aims at remeshing not only disk-like objects without holes but also closed objects, which using the concept of virtual boundary. The algorithm is proved practical and efficient in our prototype system.
