摘要：

Given a triangulation of a set of n points in the plane, each colored red or blue, we show how to compute a triangulation of just the blue points in time O(n). We apply this result to show that one can preprocess a set of disjoint regions (representing "imprecise points") in the plane having total complexity n in O(n log n) time so that if one point per region is specified with precise coordinates, a triangulation of the n points can be computed in O(n) time.
