GeoPolygon3(IEnumerable<GeoPoint3>)

Initializes a new polygon from a sequence of coplanar vertices.

public GeoPolygon3(IEnumerable<GeoPoint3> vertices)

Parameters

vertices IEnumerable<GeoPoint3>

The vertices, in order around the loop.

Remarks

Consecutive duplicates within tolerance are dropped and a repeated closing vertex is removed, so the loop closes implicitly and no zero-length edge survives. The normal and area are measured once here rather than on every read: the polygon cannot change afterwards, and the Newell sum they both come from is a full pass over the vertices.

Exceptions

ArgumentNullException

Thrown when the sequence is null.

ArgumentException

Thrown when fewer than three distinct vertices remain, when they are collinear, or when they do not lie on a common plane.

GeoPolygon3(IEnumerable<GeoPoint3>, Tolerance)

Initializes a new polygon from a sequence of coplanar vertices, within a tolerance.

public GeoPolygon3(IEnumerable<GeoPoint3> vertices, Tolerance tolerance)

Parameters

vertices IEnumerable<GeoPoint3>

The vertices, in order around the loop.

tolerance Tolerance

The tolerance deciding duplicate vertices and flatness.

GeoPolygon3(params GeoPoint3[])

Initializes a new polygon directly from vertex arguments.

public GeoPolygon3(params GeoPoint3[] vertices)

Parameters

vertices GeoPoint3[]
