Collision and self collision handling in cloth model dedicated to design garments

This article presents a method for collision handling applied to the semi rigid mass spring cloth model formerly described in Pro This method deals with the four main di culties encountered in collision handling The rst is collision detection The second is optimization of collision detection which is otherwise excessively time consuming The third is collision response The fourth is conservation of collision consistency The latter is discussed in detail and related to cases of interfering multiple collisions An original method for computation of collision response in this case of multiple collisions is presented providing a robust conservation of collision consistency Results obtained with this approach in the case of building real garments on a mannequin are presented and validate our cloth model and collision handling method
