title: Three.js: Method to convert wireframe of geometry to a THREE.Line?

  <p>It seems that to use a dashed line material, you need a THREE.Line object, but the objects used in this example were generated by rather case-specific methods.<br>
  However, one can easily create a mesh with a wireframe texture, which leads me to believe there must be an easy way (a method I have not yet found?) that converts the vertex information of a Geometry object (for example, a CubeGeometry) to a modified Geometry object suitable for use in THREE.Line which could recreate the wireframe (but with, say, dashed lines). Any ideas?</p>
  
  <p>Thanks in advance!</p>
