【Abstract】 Soft body simulation,as an important type in computer simulation field,is an essential research subject. By analyzing the physical property of soft body simulation,this paper adopts mass spring system method to model its deformation. The related principles of mass spring system are introduced at first,and then the deformation simulation method was given,which can simulate different soft body by changing the spring parameters. Based on the above method,a fast modeling method for rope is presented and used in a virtual battlefield system to simulate the transporter airborne event. The results of experiments show that the method presented can simulate the dynamic deformation behavior for soft body and can meet the needs for real time rendering.更多还原
