Abstract
We review recent progress in the study of arrangements of surfaces in higher
dimensions. This progress involves new and nearly tight bounds on the complexity
of lower envelopes, single cells, zones, and other substructures in such
arrangements, and the design of efficient algorithms (near optimal in the
worst case) for constructing and manipulating these structures. We also
discuss applications of the new results to motion planning, Voronoi diagrams,
union of geometric objects, visibility, and geometric optimization.
