Cloth

Simulation

Cloth is a very interesting and complicated subject in computer graphics. More accurately referred to as thin-shell material models, the objective is to simulate the motion of thin objects such as cloth, folded paper, clothing, etc. Throughout time people have come up with a wide array of cloth models, and no single model has proven itself strongly dominant. In order to compare the existing models, we'll break down the model into four categories:

• the equations of motion
• the integrator
• collisions
• additional features

Rendering - Discusses smoothing the simulated mesh via subdivisional surface algorithms, and techniques for rendering the cloth with a thickness or knotted pattern.
