[Algorithms] interpolate between points in 3d space

[Anceschi M. <anc...@li...>]

Hi.
I have a little problem in my 3D space game.
When my ship "fire" from a cannon i use a new local axis for the new =
object i'm firing , for calculate the next point of the laser.
But this works bad, and i  don't have much precision.
So my question is:
How can interpolate from 2 point in 3d?
(x,y,z) and (x',y',z') (suppose the second is an enemy ship).
