Claim 0:
1. A method for generating a quasistatic simulation model of a cloth object for use in a computer-based animation simulation, the method comprising:
receiving a mesh representation of the cloth object, the cloth object mesh representation comprising: a plurality of cloth vertices and locations of the plurality of cloth vertices in a three-dimensional (3D) coordinate system and cloth edges connecting pairs of cloth vertices to define cloth triangles of a triangular cloth surface mesh;
receiving a collision object mesh representation of a collision object, the collision object mesh representation comprising: a plurality of collision-object vertices and the locations of the plurality of collision-object vertices in the 3D coordinate system and collision-object edges connecting pairs of collision-object vertices to define collision-object triangles of a triangular collision-object surface mesh;
performing an iterative optimization which minimizes an energy function comprising a stretching term representative of a stretching energy of the cloth object and a bending term representative of a bending energy of the cloth object to thereby obtain a dynamic equilibrium model of the cloth object;
wherein the stretching term and the blending term are based at least in part on the cloth object mesh representation; and
wherein performing the iterative optimization comprises modelling collisions of the cloth object with the collision object.
