collision-detection

I am trying to implement the GJK-algorithm but I got stuck instantly.

The problem is to implement the Support-function that isn't O(n^2).

As it is now I'm computing the complete Minkowski difference, and then there is really no point in doing the GJK-algorithm. (or is it?)

What I mean by Support-function is the function that returns the point in the Minkowski difference that is furthest away in a specified direction. I assume this shouldn't be O(n^2) as it is in my current implementation.
