We study the collision detection of n moving balls of arbitrary sizes in 3-dimensional space. We improve both the storage and the event-handling time of the best existing KDS [1] by several logarithmic factors. Precisely, our KDS maintains O(n) certificates at the current time, uses O(nlog2n) storage, handles each event in O(log3n) time, and processes O(n2) events in the worst case, assuming that the balls follow constant-degree algebraic trajectories.
