Description:
This system for distributed real-time execution of physical simulations demonstrates efficiency increasing as a nearly linear function of the number of processors involved. Users can interactively apply forces and constraints to deformable 3D models and immediately see the physical effects of their changes. The algorithm for physical simulations uses a precomputed modal breakdown of object dynamics and non-rigid behavior, speeding dynamics computation. The network bondwidth necessary for object updates between processors is minimized by using this very compact modal representation for deformable models. The system allocates computational resources among workstations involved using a simple, efficient “market-based” strategy, avoiding the problems of central control. This system shows an interesting and rarely seen virtual environment where many users at different sites can interact together with 3D physical models.
