Examples

// Subtracts a Vector3D from a Point3D using the static Subtract method.
// Returns a Point3D.

Point3D point1 = new Point3D(10, 5, 1);
Vector3D vector1 = new Vector3D(20, 30, 40);
Point3D pointResult = new Point3D();

pointResult = Vector3D.Subtract(vector1, point1); 
// pointResult is equal to (10, 25, 39)
