TABLE RegionConvex

Defines the attributes of a given convex of a given region

Regions are the union of convex hulls and are defined in the Region table. Convexes are the intersection of halfspaces defined by the HalfSpace table. Each convex has a string representation and has some geometry properties. See also the Region and Halfspace tables
