M_Rhino_Geometry_Vector3d_Multiply

Vector3d.Multiply Method (Vector3d, Vector3d)

Multiplies two vectors together, returning the dot product (or inner product). This differs from the cross product. (Provided for languages that do not support operator overloading. You can use the * operator otherwise)

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

Syntax

C#

public static double Multiply(
	Vector3d vector1,
	Vector3d vector2
)

VB

Public Shared Function Multiply ( 
	vector1 As Vector3d,
	vector2 As Vector3d
) As Double

Parameters

 

vector1

Type: Rhino.Geometry.Vector3d
A vector.

vector2

Type: Rhino.Geometry.Vector3d
A second vector.

Return Value

Type: Double
A value that results from the evaluation of v1.Xv2.X + v1.Yv2.Y + v1.Z*v2.Z. This value equals v1.Length * v2.Length * cos(alpha), where alpha is the angle between vectors.
