| dc.description.abstract | In this paper, we propose and compare three kinds of mass-spring-damper (MSD) models of rheology object, and experimentally select the best model concerning to shape deformation and volume accuracy. The MSD model requires a few costs 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 experimental operations, shape deformation and volume of virtual rheology object based on the best model is similar to these of real rheology object. This is a case study to generate dynamic animation efficiently and precisely by the MSD model. | en_US |
