Interface RegionSelector

All Known Implementing Classes:
ConvexPolyhedralRegionSelector, CuboidRegionSelector, CylinderRegionSelector, EllipsoidRegionSelector, ExtendingCuboidRegionSelector, FuzzyRegionSelector, Polygonal2DRegionSelector, PolyhedralRegionSelector, SphereRegionSelector
public interface RegionSelector
Region selectors create Regions from a series of "selected points." They are used, for example, to allow users to create a CuboidRegion by selecting two corners of the cuboid.
