Claim One:
1. A method of simulating a movement of cloth, the method comprising: a step of simulating, using a computer, an application of a compressive force to a cloth; and a step of simulating, using the computer, an immediate buckling of the cloth, said buckling simulating step including; estimating a bent shape of a deformation unit as a function of distance between two extremities of said deformation unit; and calculating an energy of bending deformation stored in said deformation unit by estimating the bent shape of the deformation unit; wherein the estimating the bent shape of the deformation unit includes: estimating a curvature of said deformation unit as a function of distance between two extremities of said deformation unit: and estimating the bent shape of the deformation unit from the estimated curvature; wherein the curvature is derived by: K = 2 L 1 â¢ sin â¢ â¢ c - 1 â¡ ( ï˜ƒ x ij â¢ â¢ 1 ï˜„ L 1 ) K defines the curvature, X ijl defines the distance between both distal ends of the deformation unit, L 1 defines the distance between both distal ends of the deformation unit before the bent deformation occurs, and sin â¢ â¢ c â¡ ( x ) = sin â¢ â¢ x x ; â¢ and wherein the computer simulated movement of the cloth provides for a study of cloth wrinkles.
