// Multiplies a Vector3D by a Scalar using the static Multiply method.  
// Returns a Vector3D.

Vector3D vector1 = new Vector3D(20, 30, 40);
Double scalar1 = 75;
Vector3D vectorResult = new Vector3D();

vectorResult = Vector3D.Multiply(vector1, scalar1);
// vectorResult is equal to (1500, 2250, 3000)

' Multiplies a Vector3D by a Scalar using the static Multiply method.  
' Returns a Vector3D.

Dim vector1 As New Vector3D(20, 30, 40)
Dim scalar1 As Double = 75
Dim vectorResult As New Vector3D()

vectorResult = Vector3D.Multiply(vector1, scalar1)
' vectorResult is equal to (1500, 2250, 3000)
