In this paper, we propose three kinds of mass-spring-damper (MSD) models of rheology object, and experimentally evaluate the best one concerning to shape and volume accuracies. The MSD model requires a few cost to calculate force propagation and shape deformation of rheology object. For this reason, the dynamic animation can be made by a personal computer within the video-frame rate (about twenty milli-seconds). Moreover, in order to maintain deformation precision, we calibrate all coefficients of dampers and springs under many experimental data by the randomized algorithm. Then in the set of simple pushing operations, volume and shape of virtual rheology object based on the best model are extremely similar to these of real rheology object. This is a case study to generate dynamic animation efficiently and precisely by the MSD model.
