We derive analytical models of the rebound phenomenon between a ping-pong ball and the table/racket rubber. In the rebound model of the table, the determination of the type of the contact during the impact is derived as a generalized condition in the 3-dimensional space. In the model between the ball and racket rubber, it is assumed that the kinetic energy of the tangent velocity is stored as the...
The purpose of this study is to construct a force display method for virtual clay with a passive force display. It is difficult for passive systems to send feedback forces against soft objects such as clay because the systems cannot actively send feedback elasticity. However, it is essential for virtual worlds to send feedback forces from virtual clay because there are many soft objects like clay...
We model the rebound phenomenon between a ping-pong ball and the table/racket rubber. In the model between the ball and racket rubber, it is assumed that the kinetic energy of the contact velocity is stored as the potential energy due to the elasticity of the rubber. This assumption leads to that the impulse in the horizontal direction is proportional to the contact velocity. The vertical and horizontal...
