CurveCreateBooleanUnion Method (IEnumerableCurve, Double, Int32)

Calculates the boolean union of two or more closed, planar curves, and reports which input curve ended up in which output curve. Note, curves must be co-planar.

Namespace: Rhino.Geometry
Assembly: RhinoCommon (in RhinoCommon.dll)

Syntax

Copy

public static Curve[] CreateBooleanUnion(
	IEnumerable<Curve> curves,
	double tolerance,
	out int[] indexMap
)

Public Shared Function CreateBooleanUnion ( 
	curves As IEnumerable(Of Curve),
	tolerance As Double,
	<OutAttribute> ByRef indexMap As Integer()
) As Curve()

Parameters

curves: Type: System.Collections.GenericIEnumerableCurve
The co-planar curves to union.
tolerance: Type: SystemDouble
The 3d fitting and intersecting tolerance.
indexMap: Type: SystemInt32
An array with one entry per input curve. The value at index i is the index, in the returned array, of the union result that input curve i contributed to (the outer boundary curve of that result), or -1 if the input curve was not matched to any output curve. The input curves are indexed in the order they are enumerated curves.

Return Value

Type: Curve
Result curves on success, empty array if no union could be calculated.
