title: Best techniques for collision detection in video games?
body: <p>I did a lot of research on the topic, but didn't really find the exact answers I'm looking for, perhaps there isn't the one perfect solution... I was wondering how to perform 3D collision detection in video games.</p>
  
  <p>Is it best to use collision volumes like spheres and boxes and check for intersections or is there an even simpler method, like just comparing positions and vectors of objects to know if they are intersecting?</p>
