Kinetic data structure

A kinetic data structure is a data structure used to track an attribute of a geometric system that is moving continuously. For example, a kinetic convex hull data structure maintains the convex hull of a group of n {\displaystyle n} moving points. The development of kinetic data structures was motivated by computational geometry problems involving…
