Could anyone be able to tell me some where I can learn about 3d Vectors? I know all about using vectors in 2d but not in 3d, in 2d its a directon and a magnitude but what is in a 3d vector and how do I make one from a point?

that "direction and magnitude" sounds like polar version of vectors in 2d.
for must kinds of calculation it is much easier to use the ortogonal system, where you break up a vector simply in its x and y part.
to convert a vector from polar to orthogonal , do this:
x_part = cos(direction) * magnitude
y_part = sin(direction) * magnitude

in 3d you simply have one axis more...
You add vectors by simply add their x, y and z parts...

do some search on google for vectors and you should find plenty answers.

Ya polar vectors I don''t under stand how I would add that axis to it do i have 2 angles and 1 magnitude or something like that?

the answer is here :

That explains 3D vectors, what they are, etc...

Hey, cool. I see you fixed the cross product bug!
