Improvement Of Traditional Geometric Constraint Method In Collision Response

With the development of the network,the development of online fitting rooms and e-sports has become more and more popular in recent years.Cause the real-time and interactive nature of online fitting rooms and e-sports is relatively strong,so the requirements for collision response are relatively high.However,the research on realtime and interactivity in the current cloth simulation field is not very preciseness,so the field of cloth simulation has gradually become the focus of research.Among them,the collision response is a difficult point in the cloth simulation.(1)In the case of inaccurate displacement of the next time step predicted by implicit integration method in cloth simulation,a new average force method is proposed to predict the displacement of the next time step.This method predicts the displacement within a time step by force,which is more accurate than the implicit integration method that directly predicts the displacement.(2)For the penetrating phenomenon caused by self-collision of cloth,this paper improves the collision response algorithm based on the separation axis,which can solve the penetration phenomenon in the simulation process,thus obtaining stable and realistic motion details,let us in the vision Feel the real cloth movement.The experimental comparison shows that the method of using the average force to predict the displacement of the future time period is more accurate.The improved separation axis real-time collision response algorithm effectively solves the penetration phenomenon in the simulation process,and applies the algorithm to the cloth.Simulation experiments are feasible.
