Abstract

The invention discloses a method for dynamically simulating a human body and clothing in a computer. The simulation effect of different materials is achieved by setting key steps in physical simulation. The method includes the main steps of modeling the human body, processing a human body model and a clothing model, calculating clothing simulation by using mechanics knowledge, correcting after integration, impact detecting and responding. Based on a traditional mass point spring model, a large bending spring is provided to generate a wrinkle effect, corresponding spring parameters are set according to properties of the different materials, a comprehensive correction strategy is adopted in mass point clothing, and a perfect impact response scheme is provided to take characteristics of all the materials into account. Traditional clothing materials are distinguished through a great deal of parameter measurement and geometric methods, the defects that a traditional method is low in efficiency or poor in flexibility are overcome, and the different materials can be dynamically simulated.
