ABSTRACT:
A fabric model generation program, apparatus and method generate a napped fabric model that reproduces the realistic structure of each napped part. A placement portion (130) calculates an initial shape of three-dimensional napped models of the napped parts based on a degree of defiberation, minimum radius and height information, and places the napped models having the calculated initial shape on the base texture model. A flexure energy calculation portion (141) calculates a flexure energy representing the energy of the napped models attempting to flex, on the basis of a yarn stiffness coefficient. A repulsion energy calculation portion (142) calculates repulsion energy between the napped models attempting to repel each other, on the basis of a repulsion coefficient. A final shape calculation portion (143) calculates the final shape of the napped models so that a sum energy obtained by adding the flexure energy and the repulsion energy becomes minimum.
