Let F be a function that determines whether two lines intersect.
Let O be an object composed out of n bounding lines L1...Ln.
Let L be your line between A and B.

Test F(L, Li) for all lines L1..Ln. If any of the lines intersect, then L goes through O.

I need an example code.

I don't know how to calculate any line between the two points. I've been thinking of this for several days now, I need a complete fully written example.
