title: Representing a convex hull in higher dimensions (3+)
body: <p>In 2d a convex hull is represented as basically a tour of points. Seems like this representation might fall apart beyond 2 dimensions. Since, I'm going to be working with them soon, I'd like to know ahead of time what the "standard" is for doing so, if there is one for doing so, as the hulls may be used by others.</p>
  
  <p>Clarification:
  The standard I was referring to was in terms of output formats, such that from that output, a program could make use of the hull for other things.</p>
