Vector3dMultiply Method (Vector3d, Vector3d)
(Provided for languages that do not support operator overloading. You can use the * operator otherwise)
public static double Multiply( Vector3d vector1, Vector3d vector2 )
Public Shared Function Multiply ( vector1 As Vector3d, vector2 As Vector3d ) As Double
This value equals v1.Length * v2.Length * cos(alpha), where alpha is the angle between vectors.
