1. A shape visualization method comprising the steps of:
- generating three-dimensional coordinate values indicating a shape formed by assembling sewing patterns;
generating by an image processing unit a two-dimensional projection image from the generated three-dimensional coordinate values; and
displaying the generated two-dimensional projection image as a two-dimensional projection image of the shape formed by assembling said sewing patterns on a display screen of a display unit,wherein the step of generating three-dimensional coordinate values comprises substeps of;
inputting said three-dimensional coordinate values corresponding to a plurality of points on circumferences of a plurality of cross sections, having a curvature, that are located on specific height of a shape of a dress form as a reference;
calculating entire circumferential lengths of cross sections of the dress form, which are drawn from the inputted three-dimensional coordinate values and entire circumferential lengths of cross sections of a shape that should be formed by assembling sewing patterns on said dress form which are drawn from the inputted two-dimensional shape data;
calculating respectively expansion factors of cross sections, which are drawn from said entire circumferential lengths of the cross sections of the dress form and said entire circumferential lengths of the cross sections of the shape that should be formed by assembling said sewing patterns on said dress form; and
generating said new three-dimensional coordinate values indicating said shape formed by assembling the sewing patterns by expanding respectively the entire circumferences of the cross sections of the dress form indicated by said inputted three-dimensional coordinate values using predetermined functions and said expansion factors, said functions having different formulas for the cross sections, until a plurality of said entire circumferential lengths of the cross sections of the dress form coincide with certain limiting ones of said entire circumferential lengths of the cross sections of the shape that should be formed by assembling said sewing patterns on said dress form, leaving spaces with respect to other ones of said entire circumferential lengths of said shape that should be formed.

Abstract
Waist and chest lengths of sewing patterns in an assembled state are handled as shape features of the sewing pattern. The shape of a reference dummy (dress form) is expanded and changed in form so that the waist and chest lengths of the reference dummy after expansion agree with the waist and chest lengths of the shape formed by assembling the sewing patterns. Calculation of the expansion processing is conducted by a central processing unit (CPU). The shape data of the reference dummy associated with the calculation is read from a floppy disk (FD) by means of an floppy disk drive (FDD).
