Interactive simulation of deformable objects is a key component in various virtual reality medical applications. While many methods based on mass-spring models have been proposed, this paper presents an alternative that considers deformation as a result of forces propagating sequentially from one mass point to another, where matrix formulation is not required. The simulation speed is controllable by varying the scope of localized deformation. Detailed study on the propagation sequence and penetration depth is performed. Simulation speed is improved with the aid of a lookup table created by pre-computation. Results on deformable simulation and timing performance are presented. The approach is feasible for developing medical applications involving interactive simulation of soft deformable objects.
