Fiber-based digital yarn simulation method

Abstract

The invention discloses a fiber-based digital yarn simulation method which includes the steps: building a fiber texture mathematical model based on fibers of real yarns to obtain a simulation effect picture of each fiber; calculating area color block parameters of the real yarns according to spinning process parameters of the real yarns and building a yarn color block arrangement module to obtain a yarn color block simulation effect picture; building a color gradient model of simulated yarns by the aid of gradual change principles between different components in the real yarns to obtain a color gradient simulation effect picture, and simulating brightness information of the real yarns according to an illumination model; acquiring diameter data of the real yarns and simulating diameter profiles of the real yarns by the simulated yarns to obtain a diameter profile simulation effect picture; visually adjusting and optimizing the simulated yarns to obtain a simulated yarn effect picture under visual resolution. The appearance of digital yarns can be rapidly simulated to solve the problem that the appearance of the digital yarns is difficultly and visually forecasted due to complicated and changeable color matching of the digital yarns.

Description

technical field [0001] The invention relates to the technical field of yarn appearance simulation, in particular to a fiber-based digital yarn simulation method. Background technique [0002] With the rapid development of computers, more and more people in the industry are engaged in the real simulation of textiles. In the simulation process of textiles, yarn is the basic unit of fabric, and its simulation effect directly determines the simulation effect of the final fabric. Therefore, in order to promote the application of digital yarn in fabrics, the simulation of digital yarn becomes particularly important. [0003] At present, many scholars have conducted research on yarn simulation. Zhang Ruiyun et al. (Zhang Ruiyun, Li Ruqin. Computer simulation of the effect of fancy yarn embedded in the fabric [J]. Textile Journal, 2000, 21(5): 34-36.) used the real yarn extraction method to simulate the yarn . Deng Zhongming and others (Deng Zhongming, Yang Bin. Computer Simulat...
