Vector3d.VectorAngle Method (Vector3d, Vector3d, Plane)

Vector3dVectorAngle Method (Vector3d, Vector3d, Plane)

Computes the angle on a plane between two vectors.

Namespace:  Rhino.Geometry
Assembly:  RhinoCommon (in RhinoCommon.dll)
Since: 5.0
Syntax
Copy
public static double VectorAngle(
	Vector3d a,
	Vector3d b,
	Plane plane
)
Public Shared Function VectorAngle ( 
	a As Vector3d,
	b As Vector3d,
	plane As Plane
) As Double

Parameters

a
Type: Rhino.GeometryVector3d
First vector.
b
Type: Rhino.GeometryVector3d
Second vector.
plane
Type: Rhino.GeometryPlane
Two-dimensional plane on which to perform the angle measurement.

Return Value

Type: Double
On success, the angle (in radians) between a and b as projected onto the plane; RhinoMath.UnsetValue on failure.
