title: create 3D rectangle using c#
body: <p>I read about <a href="http://msdn.microsoft.com/en-us/library/system.drawing.rectangle.aspx" rel="nofollow">rectangle structure in c#</a> and the intersection function in it </p>
  
  <p>My Question is: how to custom it such that I can have a 3D rectanlge, have x,y,z coordinates </p>
  
  <p>and get it intersection with another one ?</p>
  
  <p>Any idea </p>
