Vector3d.VectorAngle Method (Vector3d, Vector3d, Vector3d)

Vector3dVectorAngle Method (Vector3d, Vector3d, Vector3d)

Computes the angle of v1, v2 with a normal vector.

Namespace:  Rhino.Geometry
Assembly:  RhinoCommon (in RhinoCommon.dll)
Since: 6.0
Syntax
Copy
public static double VectorAngle(
	Vector3d v1,
	Vector3d v2,
	Vector3d vNormal
)
Public Shared Function VectorAngle ( 
	v1 As Vector3d,
	v2 As Vector3d,
	vNormal As Vector3d
) As Double

Parameters

v1
Type: Rhino.GeometryVector3d
First vector.
v2
