TLDR: In this article, an algorithm of 3D modeling of fibers assemblies has been developed, which extends a concept of virtual location for simulation of fiber distributions in yarns cross-section from 2D to 3D modelling of yarns structure.

Abstract: An algorithm of 3D modeling of fibers assemblies has been developed. The method extends a concept of ‘virtual location’ for simulation of fiber distributions in yarns cross-section from 2D to 3D modeling of yarns structure. The distributions function used in the model demonstrates all of the properties of the ideal and real yarns. A series of further cross-section at equal intervals along the yarn length is given. Each cross-section is rotated by a pre-determined amount relative to previous one, to allow for the yarn twist and parameters of fibers migration. The fiber curve in each interval between two successive cross-sections is approximated by NURBS. Also curve generation based on twist of each fiber is determined by centerline configurations of their constituent fibers and the generative model. Each fiber is created by sweeping a closed curve along a centerline path. The simulated yarns structure using the algorithm described can model wider variety and yield an improved visual representation ...
