Vector3dMultiply 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)

	Vector3d vector1,
	Vector3d vector2


Type: Rhino.GeometryVector3d
A vector.
Type: Rhino.GeometryVector3d
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.
