Vector3d.VectorAngle Method (Vector3d, Vector3d)

Vector3dVectorAngle Method (Vector3d, Vector3d)

Compute the angle between two vectors.

This operation is commutative.

Namespace:  Rhino.Geometry
Assembly:  RhinoCommon (in RhinoCommon.dll)
Syntax
Copy
public static double VectorAngle(
	Vector3d a,
	Vector3d b
)
Public Shared Function VectorAngle ( 
	a As Vector3d,
	b As Vector3d
) As Double

Parameters

a
Type: Rhino.GeometryVector3d
First vector for angle.
b
Type: Rhino.GeometryVector3d
Second vector for angle.

Return Value

Type: Double
If the input is valid, the angle (in radians) between a and b; RhinoMath.UnsetValue otherwise.
