Abstract

We propose a new algorithm for the detection of all intersections between a set of balls and a general query object. The proposed algorithm does not impose any restrictive condition on the set of balls and utilises power diagrams to minimize the amount of intersection tests. The price for this is power diagram computation in a preprocessing step.
