Clothing seam processing and fold reinforcing method based on mass point spring model

Abstract

The invention discloses a clothing seam processing and fold reinforcing method based on a mass point spring mode. According to the method, establishing the mass point spring mode to a seam area, combing the mass point spring mode to an initial clothing model to carry out whole simulation, and carrying out refinement to a partial fold area; giving the mass point spring seam model at clothing modeling stage, and then combining the mass point spring seam model into the initial model, and carry out simulating calculation uniformly; carrying out an initial simulation firstly during a dynamic simulation stage, and for simulation results, carrying out curvature calculation by adopting a Moreton method, selecting partial maximum deformation points and spreading outwards, determining the partial fold area, carrying out mesh refinement to the partial fold area, carrying out simulation calculation again, so as to realize a more refining fold effect. The specific steps are as follows: (1) constructing the initial mass point spring model of clothing; (2) establishing a seam model, and combing the seam model into the initial model, so as to obtain a clothing whole model; (3) carrying out initial simulation to the whole model, analyzing simulation results, finding out a maximum fold point, and spreading the maximum fold point to divide the partial fold area; (4) carrying out subdivision on a triangle area in the partial fold area, and carrying out physical simulation on the whole model again, so as to obtain the more refining fold effect.

Description

technical field [0001] The invention relates to a clothing seam processing and wrinkle enhancement method based on a particle spring model, and belongs to the technical field of flexible fabric simulation. Background technique [0002] Seam pleats are wavy folds in fabric caused by the up and down twisting of seams. The sewing process is that the needle and lead thread pass through several layers of fabric continuously up and down, and the path of the final lead thread is the seam line. During the seaming process, the lead thread is subjected to a degree of tension that shrinks, causing the seam to shrink in length and thickness, putting pressure on the fabric layers it penetrates, creating seam puckering. The main form and details of clothing are folds. Through the dynamic simulation of the clothing point spring model, the folds and folds can be seen. [0003] In terms of seam simulation, Ma et al. proposed a seam model that can simulate the wrinkles at the seam, that is,...

AI Technical Summary

Problems solved by technology

[0006] (1) The higher the model resolution, the finer the simulation, and the lower the resolution, the rougher the simulation; however, a high-resolution model will bring a large amount of simulation calculation, which is time-consuming, and the calculation time of low-resolution model simulation Short, but not detailed enough

[0007] (2) Manually designing wrinkle patterns is time-consuming and requires professional skills

In addition, artificial settings can only be used for fixed frames, that is, real cloth folds change continuously, deform over time, and will dynamically separate or merge
