An Evolvin System for Simulating Clothes on Virtual

n most computer-generated films involving I virtual humans, clothes are simulated as part of the body and have no autonomous motion. In recent years, however, software has been developed to design 2D garment panels interactively and to optimize the layout of the panels on fabric. For example, Hinds and McCartney’ treated garment panels as surfaces of complex 3D shapes. They represented a static mannequin’s body as bicubic Bspline surfaces, designed the garment panels around the body, then reduced the panels to 2D cutting patterns. By contrast, other computer graphics approaches use geometric methods to model the garment panels and then superimpose harmonic and sinusoidal functions to visualize folds and drapes. Hinds and McCartney’s work addressed garment design and manufacturing in industrial contexts. So did the work of Mangen and Lasudry.’ They proposed an algorithm for finding the intersection polygon of any two polygons and applied it to the automatic optimization of laying out polygonal garment panels in 2D rectangular fabrics. Modeling more realistic clothes requires solutions to two separate problems: This cloth-modeling and
