[JAVA3D] Function of normalise()

[Jasmine Kwok]

Dear all,   Does anyone has any idea what exactly does the normalize() in Vector3d does? How come the length of the vector becomes 1.0 after it is normalized, regardless of the values of x, y & z. I need some explanation on this as the API does not explain the method's function in details. I would be thankful to anyone who can provide me with a simple explanation on this.   Cheers, Jasmine Kwok
