Vector2dMultiply Method (Vector2d, Vector2d)

Multiplies two vectors together, returning the dot product (or inner product).

(Provided for languages that do not support operator overloading. You can use the * operator otherwise)

Namespace:  Rhino.Geometry
Assembly:  RhinoCommon (in RhinoCommon.dll)
Syntax
Copy
public static double Multiply(
	Vector2d vector1,
	Vector2d vector2
)
Public Shared Function Multiply ( 
	vector1 As Vector2d,
	vector2 As Vector2d
) As Double

Parameters

vector1
Type: Rhino.GeometryVector2d
A vector.
vector2
Type: Rhino.GeometryVector2d
A second vector.

Return Value

Type: Double
A value that results from the evaluation of v1.X*v2.X + v1.Y*v2.Y.

This value equals v1.Length * v2.Length * cos(alpha), where alpha is the angle between vectors.
