Abstract: We investigate spatial acceleration structures within collision handling in scenarios with ”worst-case” spatial layout. These are scenarios where lots of collisions and interactions persist over large time intervals. We focus on acceleration structures based on uniform grids and assess their efficiency in construction, update and query. Z-curves as a technique for the mapping of spatial locality to uniform grids are analyzed to improve the cache-hit rate. The findings are applied to a deformable collision framework. Experiments are performed on scenarios that are typical for medical simulators. They often exhibit the ”worst case” spatial layout mentioned above.
