title: Getting the triangles of a mesh from its vertices
body: <p>I am having trouble implementing the Polygon-Soup Collision detection on this page. I have implemented the methods presented in that paper but I am not sure how to get the values for the CollisionPacket class. Can anyone help me in getting the values for the CollisionPacket class?</p>
  
  <p><strong>EDIT:</strong> I have implemented that, but how can get the triangles of the mesh from its vertices for the <em>checkTriangle()</em> method?</p>
