In this paper we give new techniques for designing
e cient algorithms for computational geometry prob-
lems that are too large to be solved in internal mem-
ory. We use these techniques to develop optimal and
practical algorithms for a number of important large-
scale problems. We discuss our algorithms primarily
in the context of single processor single disk machines,
a domain in which they are not only the rst known
optimal results but also of tremendous practical value.
Our methods also produce the rst known optimal al-
gorithms for a wide range of two-level and hierarchical
multilevel memory models, including parallel models.
