Abstract: Let C be a set of n axisaligned cubes in R 3, and let U(C) denote the union of C. We present an algorithmthat can compute the volume of U(C) in time O(n 4/3 log n). The previously best known algorithm, by Overmars and Yap, computes the volume of the union ofany n axisaligned boxes in R 3 in O(n 3/2log n) time. Copyright 2007 ACM.
