Haptic Pottery Modeling Using Circular Sector Element Method

This paper presents an efficient modeling system of virtual pottery in which the user can deform a body of virtual clay with a haptic tool. The clay body is represented with a set of circular sector elements based on the cylindrical symmetry of pottery. The circular sector element method allows much finer spatial resolution for modeling than previous techniques. Also described are efficient algorithms for collision detection and response where the viscosity of virtual clay is simulated along with the friction due to the rotating potter's wheel. Empirical evaluation showed that the modeling system is computationally efficient, is intuitive to use, and provides convincing model deformation and force feedback.
