Convex Hulls are essential for a Collision-Detection system. Without Convex-Hulls, a game engine would not be able to detect collision among convex objects. Unfortunately, computing Convex-Hulls is complicated and time-consuming.  Luckily for us, Joseph O'Rourke came to the rescue.

In Game Engine development, you always deal with Dot Products, Cross Products, Transformations, Inverses, etc. You may not know why or when you should use these operations. And that is why I wrote this article. I want to teach you why and when these operations should be used.

Six tips to keep in mind when developing a Collision Detection System for your Game Engine.
