selecting an elementary interval associated with a stratification of a two-dimensional space;
initializing, using a processor, at least one data structure for the elementary interval that indicates one or more valid regions within the elementary interval, wherein the one or more valid regions are identified based at least on a set of stratifications related to the two-dimensional space, wherein the set of stratifications includes at least two different stratifications;
identifying at least one valid region of the one or more valid regions based on the at least one data structure; and
