Physically Based Deformation using Lattice Meshes

Abstract

There has been much research on production of realistic deformation animations based on physically based 3D model. If we apply a physically based model to a polygon geometry, a large number of calculations are needed if the complexity of the 3D model is high. We propose a method of calculating the deformation in which a physically based model and axes are applied to lattice meshes to generate a free form surface. This method reduces the calculation cost, and a deformation simulation considering the interior properties of the solid model can be easily realized with it.
