public abstract class PolyhedralSurfaceExpression<T extends org.geolatte.geom.PolyHedralSurface>
extends SurfaceExpression<T>

A PolyhedralSurface is a contiguous collection of polygons, which share common boundary segments. For each pair of polygons that “touch”, the common boundary shall be expressible as a finite collection of LineStrings. Each such LineString shall be part of the boundary of at most 2 Polygon patches.

Methods

Modifier and Type	Method and Description
BooleanExpression	isClosed() Returns 1 (True) if the polygon closes on itself, and thus has no boundary and encloses a solid
NumberExpression<Integer>	numPatches() Returns the number of including polygons
PolygonExpression<?>	patchN(int n) Returns a polygon in this surface, the order is arbitrary.
