A preliminary study of a deformable body model for clothing simulation

Abstract

The body model which has been utilized in our clothing simulation does not deform and gives a boundary condition for mechanical calculation. To determine the shape of clothing in the case where clothing and body mechanically interact with each other, the body model used for this purpose has to be deformable. In this study, basic techniques for realization of the deformable body model were investigated. A tetrahedron was defined as a fundamental element for mechanical calculation of solid, and it was formulated with ordinal strain. Four kinds of cubes consisting of six tetrahedrons were defined as basic geometrical elements for constructing solids. Two kinds of cantilevers were constructed from the cubes and mechanical simulation was carried out with proper mechanical properties. A method of estimating internal mechanical properties of the human body was tested. The method is a modification of the simulation and is one of inverse problems. Treatment of collision is required for the simulation in which clothing and body mechanically interact with each other. The treatment of collision is based on a triangular element, and the processes consist of its detection and resolution. Simulation of a right cylinder solid wound by fabric like pipe was carried out to check collision treatment.
