Abstract : This research report describes a cloth simulation system including nonlinear behaviors. Our cloth model simulates the fabric as a complex yarn interlacing structure. This approach allows us to deal with the yarn scale problem by including the nonlinear interactions happening inside this structure. This model has three different components: the traction, the bending and the shearing. We also add new friction terms in order to reproduce the yarn interlacing structure and the nonlinear properties of a real cloth. Moreover, this representation avoids a detailed 3D geometric model of yarns which is almost always unusable in computer graphics. Furthermore, our physical model is based on the Kawabata Evaluation System (KES). It reproduces the behavior of a cloth using the parameters coming from direct measurements on real clothes. Therefore we propose an identification procedure to compute all the physical parameters of our model from the KES curves. Since many textile manufacturers use this KES to design their fabrics, we are able to accurately simulate their real fabrics in computer graphics using the manufacturer's parameters. The simulation of a complete garment made of these fabrics could also be achieved in a virtual fashion show to visualize its characteristics and/or flaws for example.
