A Realization Method of Dynamic Simulation of Human Clothing in Computer

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.

Description

technical field [0001] The invention relates to the technical field of computer graphics, in particular to a method for realizing dynamic simulation of human body clothing in a computer in the technical field of computer clothing simulation. Background technique [0002] Virtual fitting is a hot issue in the field of virtual reality today, and related technologies have been applied to many fields, such as online shopping, CG movies, 3D games, 3D animation, etc. Online clothing shopping is undoubtedly the most important field of virtual fitting applications. This emerging technology has brought great convenience to consumers, and has the advantages of cost saving, time saving, and more diversified choices. [0003] At present, the physics-based simulation method is the mainstream of dynamic clothing simulation, because this method can achieve better visual effects and meet the real-time requirements of the fitting system. In addition, compared with the geometric simulation me...

Problems solved by technology

The disadvantage is that the preprocessing time is long, and if the clothes are embedded in the human body, it will directly affect the final experimental results

This method has high authenticity, but it is not suitable for more complex fabrics due to its time-consuming. In addition, each material needs to measure a lot of parameters, which limits the scalability of this method to a certain extent.

[0007] In summary, the shortcomings of the existing methods mainly include: the body model in Document 1 lacks flexibility in changing the body shape, and it is difficult to complete continuous actions after building a human body; the material realization method based on geometry in Document 2 is not conducive to the realization of dynamic effects. Physically-based material implementation, but too many parameters are added, which directly affects the efficiency of the fitting system, and the simulation of more complex clothing models will lack real-time performance
