From Measured Fabric to the Simulation of Cloth

Cloth simulation and fabric measurement are tightly linked areas of research. In order to obtain high quality animations of dressed models, the properties of the simulated garment must first be evaluated in an accurate and adapted way. As cloth is a very complex, isotropic material, the evaluation of its properties is difficult to achieve, and various approaches exist. Depending on the design of the simulation engine, the measurements will be done differently, so that the outputted parameters match the inputs required by the simulator. Various issues must be considered, and depending on the complexity of the simulated garments, tradeoffs must be made in order to reconcile the real features of the cloth (stitches, layers...) and the computational capacities of the simulator (numerical integration, collision detection...)
