Title: Knit product grading method and grading system
Inventor: TERAI KOICHI
IPC: D04B37/00
Filed: 2020-02-06
Abstract: CONSTITUTION: For a knit product to be graded, 2 sizes of pattern data are converted into knit data. Feature points that specify the shape of the knit product are generated for the converted 2 sizes of pattern data and an intermediate shape that specifies the shape of the knit product among the feature points are generated. The feature points and the intermediate shape for a target size are generated by interpolating or extrapolating among the feature points and the intermediate shapes according to the target size of the knit product. A closed loop is generated by connecting the feature points and the intermediate shapes and knit data for the target size is created by arranging a knit in a pattern specified by the loop.EFFECT: Since knit data such as an intermediate size can be generated from 2 sizes of knit data without passing through pattern data such as an intermediate size, conversion from the pattern data to the knit data is unnecessary for the intermediate size and the like.SELECTED DRAWING: Figure 3
