| Abstract: | Parenchyma deformation have become choke point in visual surgery technique on the basis account of different subjects.A simple style of mass-spring system modeling technology is adopted in gum deformation, particle force and equation groups computing methods are researched on commonly modeling approach.Based on the feature of STL teeth models,data structure of simple style mass-spring system is presented,and used pervasion depth controls computed value and accuracy.The results showed this system can stimulate the deformation change in time and has good display result. |
