Force
Résumé
Physical modelling and interactive physically-based computer models and simulation rise the new important question of the increase of the presence and believability of virtual worlds. The notion of force is then at the core of the modelling process and interaction, since it intervenes in the computation processes and algorithms, and in the interaction process by means of force feedback devices. It is consequently useful to remind fundamental properties of the concept of force and to have in mind the non-trivial transformations caused by their computer implementation.
