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.

Method Detail

numPatches

public NumberExpression<Integer> numPatches()

Returns the number of including polygons

Returns:

number of polygons

patchN

public PolygonExpression<?> patchN(int n)

Returns a polygon in this surface, the order is arbitrary.

Parameters:

n - one based index

Returns:

polygon at index

isClosed

public BooleanExpression isClosed()
