Vector3d.VectorAngle Method (Vector3d, Vector3d, Plane)

Computes the angle on a plane between two vectors.

Namespace: Rhino.Geometry
Assembly: RhinoCommon (in RhinoCommon.dll) Version: Rhino 6.0

Syntax

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

a: Type: Rhino.Geometry.Vector3d
First vector.
b: Type: Rhino.Geometry.Vector3d
Second vector.
plane: Type: Rhino.Geometry.Plane
Two-dimensional plane on which to perform the angle measurement.

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