OT: Some line math help?

[dabeav]

Quick question. I am looking for a fast method to find there intersection point of 2 3D line segments that lye on the same plane. Please note, they may intersect once, infinatly or not at all. Anyone have a quick equation to do this with two line segments. Thanks for the help.
