Embodiment

[0042] exist Figure 1 to Figure 11 In , examples, modifications thereof, and conventional examples are shown. figure 1 (A) shows the knitting data of the knitting product (shoe upper) to be simulated, and the knitting data (information related to knitting of the knitted fabric) is divided into a plurality of parts. The gray or white parts in the picture are woven fabrics, and the black parts are not woven fabrics. The horizontal band at the lower end of (A) is a part of the shoe opening, and is shown compressed. The gray parts in (A) are parts, and the parts other than the toe and the instep are woven by turning back the stitches, and each part is connected to each other. In addition, the heel portion of the shoe upper remains separated from the left and right and is not connected to each other. The uppermost part of (A) is a tiptoe, and the light gray part is a part following the upper part of the mouth opening. For example, the knitting is performed in order from the b...

Abstract

The invention discloses a knit simulation method and a knit simulation system. The virtual shape of knit product comprising plural parts mutually divided in the knit data is simulated. The connectioninformation regarding how said parts are mutually connected is obtained based upon the knit data or the pattern data of the knit product, and the plural parts are mutually connected based upon the obtained connection information. The virtual shape of the knit product is deformed by deforming the plural parts according to the forces acting on the plural parts. At least one of the plural parts is stretched automatically or according to at least an instruction by a user, and then, the virtual shape of the knit product is re-deformed to a natural shape by re-deforming the plural parts according tothe forces acting on the plural parts. Then, stitches are allocated within the plural parts, and the allocation of the stitches is smoothed within the plural parts.

Description

technical field [0001] The present invention relates to shape simulation of woven products having multiple regions. Background technique [0002] In the weaving simulation, the finished shape of the woven product is simulated based on the weaving data. Therefore, considering the force acting on the loop (coil) of the knitted product, the stable shape of the knitted product is simulated. [0003] When the number of stitches is large, the calculation time until the shape of the knitted product becomes stable in the simulation becomes long. Therefore, in Patent Document 1 (WO2009 / 031468), the woven product is divided into a plurality of polygons, and the stable shape of the woven product is simulated in units of polygons. Next, arrange the coils within the polygon to smooth the arrangement of the coils.
