Multi-Resolution Meshes Deformation Based on the Offset of Sketching

Abstract

The 3D meshes deformation is the deformation on 3D mesh models under users want, and keeping the mesh details at the same time. In this paper, we present a technique for multi-resolution meshes deformation based on the offset of sketching. In order to decrease the computational cost, the proposed method reduces the number of vertices involved in the deformation. First, we construct a simplified mesh using a modified CPM algorithm; and then correct Laplacian coordinates rotation by the offset of sketching and generate the deformed models by solving linear system in least squares sense with Gauss-Seidel algorithm; finally, series of details are added to the deformed simplified mesh. In contrast with the traditional deformation, our method can achieve natural deformed models more efficiently.
