This repository contains a simple cloth simulation which models a Hookean material. In particular, it simulates the "weft and weave" using a mass-spring system, with a maximum deformation ratio, using the procedure described in a paper by Xavier Provot at INRIA in 1995. The masses comprising the cloth form a rectangular grid, and are connected to their immediate horizontal and vertical neighbors. Each node is also connected to its immediate diagonal neighbors, and has "weft" and "weave" connections to its neighbors' immediate neighbors. See Figure 1 in the linked paper to see a diagram of the connections.
A live demo is available here. The demo includes a user-controllable wind force. The wind force is just a simple constant-valued vector field; there isn't any simulation of compressible flow or its interaction with the cloth. This results in a reduction of accuracy to the real world, but the wind effect allows interaction with the cloth and shows the cloth dynamics quite well. There also is not any self-collision handling, so the cloth surface can intersect itself.
