This paper presents the following approximation algorithms for computing a minimum cost sequence of planes to cut a convex polyhedron P of n vertices out of a sphere Q: an O(n log n) time O(log2 n)-factor approximation, an O(n1.5 log n) time O(log n)-factor approximation, and an O(1)-factor approximation with exponential running time. Our results significantly improve upon the previous O(n3) time O(log2 n)-factor approximation solution.
