GeoPolylineArc3(IEnumerable<GeoPoint3>)

Initializes a chain of straight pieces.

public GeoPolylineArc3(IEnumerable<GeoPoint3> vertices)

Parameters

vertices IEnumerable<GeoPoint3>

The vertices, in order; at least two, and no two neighbours in the same place.

Exceptions

ArgumentNullException

Thrown when the vertices are null.

ArgumentException

Thrown when fewer than two distinct vertices are given.

GeoPolylineArc3(IEnumerable<GeoPoint3>, IEnumerable<double>, IEnumerable<GeoVector3>)

Initializes a chain whose pieces may be arcs.

public GeoPolylineArc3(IEnumerable<GeoPoint3> vertices, IEnumerable<double> bulges, IEnumerable<GeoVector3> normals)

Parameters

vertices IEnumerable<GeoPoint3>

The vertices, in order; at least two, and no two neighbours in the same place.

bulges IEnumerable<double>

The bulge of the edge leaving each vertex; null or short means the rest are straight, and anything past the last edge is ignored.

normals IEnumerable<GeoVector3>

The plane each bulge is read about, laid out the way the bulges are; only wanted where a bulge is not nought.

Exceptions

ArgumentNullException

Thrown when the vertices are null.

ArgumentException

Thrown when fewer than two distinct vertices are given, or when a bulge that is not nought comes with no usable plane.

GeoPolylineArc3(IEnumerable<GeoPoint3>, IEnumerable<double>, IEnumerable<GeoVector3>, Tolerance)

Initializes a chain whose pieces may be arcs, within a tolerance.

public GeoPolylineArc3(IEnumerable<GeoPoint3> vertices, IEnumerable<double> bulges, IEnumerable<GeoVector3> normals, Tolerance tolerance)

Parameters

vertices IEnumerable<GeoPoint3>

The vertices, in order; at least two, and no two neighbours in the same place.

bulges IEnumerable<double>

The bulge of the edge leaving each vertex; null or short means the rest are straight.

normals IEnumerable<GeoVector3>

The plane each bulge is read about; only wanted where a bulge is not nought.

tolerance Tolerance

The tolerance, which decides when two vertices are in the same place and how square to its chord a normal must be.

GeoPolylineArc3(IEnumerable<GeoEdge3>)

Initializes a chain from edges that run end to end.

public GeoPolylineArc3(IEnumerable<GeoEdge3> edges)

Parameters

edges IEnumerable<GeoEdge3>

The edges, each starting where the one before it ended.

Exceptions

ArgumentNullException

Thrown when the edges are null.

ArgumentException

Thrown when no edges are given, or one does not start where the one before it ended.

GeoPolylineArc3(GeoPolyline3)

Initializes a chain from a straight one, with no bulges.

public GeoPolylineArc3(GeoPolyline3 polyline)

Parameters

polyline GeoPolyline3

The straight chain to widen.

Remarks

Widening loses nothing: every edge simply carries a bulge of zero. It is Flatten() going the other way that throws the curves away.

Exceptions

ArgumentNullException

Thrown when the chain is null.
