Embodiment Construction

[0148] Due to the existing hyperelasticity problem and slow calculation speed in the existing fabric deformation simulation method, it may cause a lot of inconvenience. Therefore, the embodiment of the present invention provides a fabric deformation simulation method. The model is based on the classical spring- On the basis of the proton model, the concept of semi-rigid spline is introduced, which fully considers the stretchability, compression, shear, bending and surface roughness of the fabric, and effectively solves the anisotropy and hyperelasticity in fabric simulation. problem, improving the realism of fabric simulation.

[0149] In terms of numerical integration, the method of the present invention uses the Verlet integral method, which has a greater improvement in speed and calculation stability, compared with the disadvantage of slow solution speed of the traditional explicit Euler and implicit Euler.

[0150] In terms of collision processing, the method of the presen...

Abstract

The invention discloses a fabric deformation simulation method which, based on the classic spring-mass model, introduces the concept of a semi-rigid spline, and takes into full consideration of stretching property, compressing property, cutting property, bending property and surface roughness of the fabric, and effectively addresses the problem of anisotropy and superelasticity in fabric deformation simulation, and increases real sense of fabric deformation simulation. In aspect of numerical integration, compared with traditional explicit euler method and implicit euler method which have defects of slow solution speed, the method of the invention Verlet integration method which has substantial increase in velocity and computing stability. In aspect of collision treatment, the method further simplifies a collision model, and only considers collisions of "top pint-triangle" type and "edge-edge" type that occur in large amount in fabric simulation, which effectively reduces times for collision treatment and accelerates computing velocity.

Description

technical field [0001] The invention relates to a method for fabric deformation simulation. Background technique [0002] Since the 1980s, the simulation of fabric deformation has been a research hotspot in the field of computer graphics. The spring-proton model has been widely used in fabric simulation because of its simple principle and easy realization. Simulation results are distorted. Fabric simulation involves numerical integral calculation of motion equations and a large number of collision processing, which often become the performance bottleneck of simulation. In terms of numerical integration, the traditional explicit Euler and implicit Euler have the disadvantage of slow solution speed. Contents of the invention [0003] The object of the present invention is to provide a method for fabric deformation simulation aiming at the deficiencies of the prior art. [0004] The purpose of the present invention is achieved through the following technical solutions: a ...
