In most cases, a coarse volumetric mesh is a regular structured grid that covers all the primitives in a fine geometry, and thus mesh generation is simple, fast, and robust.The deformation of a fine geometry is interpolated with that of a coarse volumetric mesh in a master-slave manner.This enables separation of the model for graphics rendering and for mechanical analysis.As a result, good visual plausibility and a reasonable computational cost are achieved at the same time.The embedding technique is not limited to applications for polygonal surfaces but can also be applied to volume data such as medical images.We
