Interacting Deformable Objects

The realistic simulation of complex deformable objects at interactive rates comprises a number of challenging problems, including deformable modeling, collision detection, and collision response.
1. The deformable modeling approach has to provide interactive update rates, while guaranteeing a stable simulation. Furthermore, the approach has to represent objects with varying elasto-mechanical properties.
2. The collision detection algorithm has to handle geometrically complex objects, and also large numbers of potentially colliding objects. In particular, the algorithm has to consider the dynamic deformation of all objects.
3. The collision response method has to handle colliding and resting contacts among multiple deformable objects in a robust and consistent way. The method has to consider the fact that only sampled collision information is available due to the discretized object representations and the discrete-time simulation. The presentation discusses solutions to the aforementioned simulation aspects. Interactive software demonstrations illustrate all models, algorithms, and their potential for applications such as surgery simulation.
