Modeling and deformation method of human body model based on range data

A cloth simulation system must generate a human body model based on measured data obtained from range data. We propose modeling and deformation methods based on such data. In our system, the human body is modeled by layered metaballs which correspond to the horizontal cross-section of the body. For each cross-section, metaballs are generated by measured sample points on the boundary of the cross-section. In order to fit the metaball surface with the sampling points, we employed the steepest descent method. For body deformation, the sampling points on the cross-section are smoothly moved using Bezier curves. To show the effectiveness of the proposed method, we demonstrate fitting and deformation of the two human body models to be used for the cloth simulation.
