DETAIL-PRESERVED LOCAL DEFORMATIO N ALGORITHM FOR MESH SURFACE
摘要
Abstract
For the problem that the direct manipulation of free-form deformation algorithm is poor in detail preservation when conducting local deformation on large-scale mesh model,we bring forward a full automated mesh model local deformation algorithm which relies on the theoretical basis of discrete Poisson equation and differential operator on mesh surface.The basic idea of this algorithm is to obtain the deformation area through automatic estimation of the algorithm according to the moving the user does on control vertex of the model and the surface geometry feature of mesh at first,then to map user’s editing modification on control vertex onto gradient field modification for the deformation area.Finally,a mesh with deformation is derived through the reconstruction using Poisson equation.The advantage of this algorithm is to omit the process of manually designating the deformation area on the basis that the local geometric detail of the mesh model surface is kept preserved.关键词
