   3D Lines point of intersect where the y axis = 0
  Ive used the Irrlicht function getRayFromScreenCoordinates and i would like to know if there is a way to get the point at which the ray intersects the y axis at 0Thanks

If so, that's just a special case of the general ray-plane intersection test. (If not, perhaps you can clarify what you mean exactly.)
