title: Overlapping cubes
body: <p>I'm trying to determine if two cubes overlap. I've read up on <a href="https://stackoverflow.com/questions/306316/determine-if-two-rectangles-overlap-each-other">overlapping rectangles</a>, but I'm not sure how to translate it into the third dimension.</p>
  
  <p>My goal is to generate a number of randomly positioned and sized non-overlapping cubes.</p>
  
  <p>These cubes are represented on a x,y,z Cartesian plane.</p>
