| Abstract: | A compound deformation algorithm based on physics is proposed,which is adapted to the conventional simulation of the deformable objects that is poor at dynamic performance.This new algorithm is decoupled local and global deformation by using a filling sphere modeling approach.Through layered rendering of virtual force,the spring-mass system on the surface enhances immersion for virtual environment.For the problem of deformation hysteresis,correcting the position of barycenter using shape matching makes the result of dynamic simulation more exact. |
