Detailed Description

An IPolyhedralSurface is a contiguous collection of polygons, which share common boundary segments.

For each pair of IPolygons that "touch", the common boundary shall be expressible as a finite collection of ILineStrings such ILineString shall be part of the boundary of at most 2 IPolygon patches. A ITIN (triangulated irregular network) is a IPolyhedralSurface consisting only of ITriangle patches.

For any two IPolygons that share a common boundary, the "top" of the IPolygon shall be consistent. This means that when two ILinearRings from these two IPolygons traverse the common boundary segment, they do so in opposite directions. Since the IPolyhedral surface is contiguous, all IPolygons will be thus consistently oriented. This means that a non-oriented surface (such as Möbius band) shall not have single surface representations. They may be represented by a IMultiSurface.

If each such ILineString is the boundary of exactly 2 IPolygon patches, then the IPolyhedralSurface is a simple, closed polyhedron and is topologically isomorphic to the surface of a sphere. By the Jordan Surface Theorem (Jordan's Theorem for 2-spheres), such polyhedrons enclose a solid topologically isomorphic to the interior of a sphere; the ball. In this case, the "top" of the surface will either point inward or outward of the enclosed finite solid. If outward, the surface is the exterior boundary of the enclosed surface. If inward, the surface is the interior of the infinite complement of the enclosed solid. A Ball with some number of voids (holes) inside can thus be presented as one exterior boundary shell, and some number in interior boundary shells.
