Interactive simulation of the teeth cleaning process using volumetric prototypes.

In this paper, an interactive simulation system for teeth cleaning is presented. This simulation system offers assistance for optimizing design and manufacturing of new toothbrushes. Data acquisition and pre-processing techniques for the model generation are shown and the mathematical method for modelling of the elastic behaviour of the toothbrushes parts is explained. Afterwards, a new approach to collision detection based on simple volumetric prototypes is described, user interaction is discussed and results of the project are shown.
