This paper describes a physically(cid:12)based model for animating cloth objects(cid:13) derived from elastically de(cid:12) formable models(cid:13) and improved in order to take into account the non(cid:12)elastic properties of woven fabrics(cid:2) A cloth object is (cid:14)rst approximated to a deformable surface composed of a network of massesand springs(cid:13) the movement of which is evaluated using the numer(cid:12) ical integration of the fundamental law of dynamics(cid:2) We show that when a concentration of high stresses occurs in a small region of the surface(cid:13) the local de(cid:12) formation becomes unrealistic compared to real de(cid:12) formations of textiles(cid:2) With such an elastic model(cid:13) the only solution to decrease these deformations has been so far to increase the sti(cid:15)ness of the deformed springs(cid:13) but we show that it dramatically increases the cost of the algorithm(cid:2) We present therefore a new method to adapt our model to the particularly sti(cid:15) properties of textiles(cid:13) inspired from dynamic in(cid:12) verse procedures(cid:2)
