Vector3d.Multiply (Vector3d, Vector3d)

Public Operator

Multiplies two vectors together, returning the dot product (or inner product). This differs from the cross product.

Namespace: Rhino.Geometry

Assembly: RhinoCommon (in RhinoCommon.dll)

**Since:**5.0

Syntax

public static double operator *(
  Vector3d vector1,
  Vector3d vector2
)

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.X*v2.X + v1.Y*v2.Y + v1.Z*v2.Z.

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