A fast three-dimensional simulation method for weft-knitted fabric structure

Abstract

The invention discloses a method for three-dimensional-imitated rapid simulation of a weft-knitted fabric structure. During computer aided design of a weft-knitted fabric, coil graphic primitives treated by surface lightness processing are partitioned longitudinally and then layered and combined according to a certain sequence, so that a two-dimensional graph can embody three-dimensional inter-loop relations between coils. In this way, the weft-knitted fabric structure can be simulated rapidly. The method has the advantages that the coils with different structures and different shapes can be combined; and the method is used to express the diversified weft-knitted fabric structures. The method disclosed by the invention has the advantages of convenient operations, the high three-dimensional sense and a fast speed, etc.

Description

Technical field: [0001] The invention belongs to the technical field of textile weaving, in particular to a three-dimensional rapid simulation method for weft-knitted fabric structure. Background technique: [0002] Knitted fabric structure simulation technology is one of the key technologies for computer-aided knitted fabric design. By simulating the loop structure, the connection relationship between loops can be observed and understood intuitively, and the deformation and surface texture of the fabric can be predicted to a certain extent. [0003] Because the loops in knitted fabrics are bent in three dimensions, and the loops are interlaced with each other, most of the simulations of the loop structure of knitted fabrics currently use three-dimensional methods. When the number of coils is large, the speed becomes slower and cannot be displayed in real time. There is a big difference between the surface texture simulation of the three-dimensional coil and the real yarn. ...

AI Technical Summary

Problems solved by technology

[0003] Since the loops in knitted fabrics are curved in three dimensions, and the loops are interlaced with each other, most of the simulations of the loop structure of knitted fabrics currently use three-dimensional methods. When the number of coils is large, the speed becomes slower and cannot be displayed in real time

There is a big difference between the surface texture simulation of 3D coils and the real yarn. At present, the simulation technology of 3D yarn hairiness still has speed constraints, that is, the more realistic the simulation, the longer the time.

Due to the limitations of the three-dimensional coil modeling technology, when simulating complex fabric structures, cross collisions between coils are prone to occur. Therefore, each coil with different structures must be modeled separately, which is a heavy workload and inflexible to use.
