Intersect(GeoPolygonArc2, GeoPolygonArc2)

Gets what both loops cover, with the arcs cut into straight pieces first.

public static GeoFace2[] Intersect(GeoPolygonArc2 loop1, GeoPolygonArc2 loop2)

Parameters

loop1 GeoPolygonArc2

The first loop, which may curve.

loop2 GeoPolygonArc2

The second loop, which may curve.

Returns

GeoFace2[]

The faces of the result, straight throughout.

Remarks

Each arc is cut finely enough to stray no further than the automatic share of its radius, about a fifth of a percent. Use the overload that names a chord tolerance when that is not fine enough.

Exceptions

ArgumentNullException

Thrown when either loop is null.

Intersect(GeoPolygonArc2, GeoPolygonArc2, Tolerance)

Gets what both loops cover, with the arcs cut into straight pieces first, within a tolerance.

public static GeoFace2[] Intersect(GeoPolygonArc2 loop1, GeoPolygonArc2 loop2, Tolerance tolerance)

Parameters

loop1 GeoPolygonArc2

loop2 GeoPolygonArc2

tolerance Tolerance

Returns

GeoFace2[]

Exceptions

ArgumentNullException

Thrown when either loop is null.

Intersect(GeoPolygonArc2, GeoPolygonArc2, double)

Gets what both loops cover, cutting the arcs no further than a chord tolerance from the curve.

public static GeoFace2[] Intersect(GeoPolygonArc2 loop1, GeoPolygonArc2 loop2, double chordTolerance)

Parameters

loop1 GeoPolygonArc2

The first loop, which may curve.

loop2 GeoPolygonArc2

The second loop, which may curve.

chordTolerance double

The largest gap allowed between a piece and the arc it replaces, in drawing units. Zero picks the automatic share of each radius.

Returns

GeoFace2[]

The faces of the result, straight throughout.

Exceptions

ArgumentNullException

Thrown when either loop is null.

Intersect(GeoPolygonArc2, GeoPolygonArc2, double, Tolerance)
