title: How can I draw edges as an array?
body: <p>I have 3d model with tessellated geometry (I have array of vertexes and triangles) and I have also array of edges from original non-tessellated geometry. I can't find any tutorial/example with description how to display array of edges and documentation of Three.js is incomplete:</p>
  
  <pre><code>//
  // Cube geometry
  //
  //   4+--------+7
  //   /|       /|
  // 5+--------+6|
  //  | |      | |
  //  |0+------|-+3
  //  |/       |/
  // 1+--------+2
  //
  var cube_vertices = [
      [-1.0, -1.0, -1.0],
      [ 1.0, -1.0, -1.0],
      [ 1.0,  1.0, -1.0],
      [-1.0,  1.0, -1.0],
      [-1.0, -1.0,  1.0],
      [ 1.0, -1.0,  1.0],
      [ 1.0,  1.0,  1.0],
      [-1.0,  1.0,  1.0]
  ];
  var cube_edges = [
      [0, 1],
      [1, 2],
      [2, 3],
      [3, 0],
      [0, 4],
      [1, 5],
      [2, 6],
      [3, 7],
      [4, 5],
      [5, 6],
      [6, 7],
      [7, 0]
  ];
  </code></pre>
  
  <p>Does anybody have any suggestion? </p>
