Patent ID: 8300044

Claim:
A non-transitory, computer-readable recording medium which stores a knitting structure model generation program for generating a knitting structure model of a warp knit in a virtual three-dimensional space, the program causing a computer to function as: a path information acquisition portion for acquiring yarn path information representing a yarn path in a warp direction of the warp knit; an array information acquisition portion for acquiring array information representing an array position in a weft direction of the yarn path represented by the yarn path information; an initial model generation portion for generating in the virtual three-dimensional space an initial model of the warp knit in which the yarn path is expressed in a broken line, in accordance with the yarn path information and the array information; a position correction portion for setting mass points of a yarn in characteristic positions on the yarn path constituting the initial model, generating a dynamic model of the warp knit by connecting the mass points by using an edge applied with a dynamic characteristic of an actual yarn that is obtained by measuring the actual yarn, and correcting the position of each mass point by solving a motion equation of each mass point; and a three-dimensional model generation portion for forming a surface expressing a yarn surface on a yarn path represented by the edge connected to the mass points whose positions are corrected by the position correction portion, and thereby generating a three-dimensional model of the warp knit, wherein the dynamic model has a coarse dynamic model that does not take into account the thickness of a yarn and a dense dynamic model that takes into account the thickness of a yarn, and the position correction portion uses the coarse dynamic model until the positions of the mass points converge within a predetermined range, and uses the dense dynamic model after the positions of the mass points converge within the predetermined range.
