摘要

—In this paper, we propose a method to simulatesoft bodies by using gravitational force, spring and dampingforces between surface points, and internal molecularpressure forces. We consider a 3D soft body modelcomposed of mesh points that define the body’s surface suchthat the points are connected by springs and influenced byinternal molecular pressure forces. These pressure forceshave been modeled on gaseous molecular interactions.Simulation of soft body with internal pressure forces isknown to become unstable when high constants are usedand is averted using an implicit integration method. Wepropose an approximation to this implicit integrationmethod that considerably reduces the number ofcomputations in the algorithm. Our results show that theproposed method realistically simulates soft bodies andimproves performance of the implicit integration method.
