A 3D Vector is the direction and magnitude. You need to restate your question with more information on what you are trying to do.

Do you mean the angles/sphere coords?

Because
x = r*cos(u)*sin(v)
y = r*sin(u)*sin(v)
z = r*cos(v)

you get

r = sqrt(x^2 + y^2 + z^2)

u = arctan(y/x)

v = arctan(z/sqrt(x^2+y^2))

Thanks ga, i thumbed through a calculus book to see the differant methods to describe its direction and yes spherical coords is the way i wanted.
