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)

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

vector1

Type: Rhino.Geometry.Vector3d
A vector.

vector2

Type: Rhino.Geometry.Vector3d
A second vector.

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.
