Title : A multiresolution framework for real-time simulation interactions

Abstract : Most interactive simulations need a collision detection system. First, this system requires the querying of the proximity between the objects and then the computing of the behaviour to be applied. In order to perform these queries, the objects present in a scene are either classified in a tree, in a proximity graph, or embedded inside a registration grid.
Our work present a new collision detection model based on two main concepts : representing the environment with a combinatorial multiresolution map, and tracking in real-time particles embedded inside this map. This model allows us to simulate complex environments while following in real-time the entities that are evolving within it.
We present our framework used to register and update the registration of particles, edges and surfaces in volumetric combinatorial multiresolution maps.
Results have been validated first in 2D with a crowd simulation application and then in 3D, in the medical field, with a percutaneous surgery simulation.
