title: Least Square Conformal Map Charts growing
body: <p>I'm trying to implement the <a href="http://alice.loria.fr/index.php/publications.html?Paper=lscm@2002" rel="nofollow noreferrer">LSCM</a> algorithm for texture unwrap. So far I've done detecting and growing features, as you can see on the screenshots:</p>

  <p>As for the algorithm itself, as it is described in ALICE, now I should create (or "grow") charts using these seams. ALICE's LSCM uses some nifty terminology I can't understand (my maths knowledge is really poor). The thing I can not understand is what is a <em>facet</em> and how I can find the distance from my <em>half-edge</em> to the <em>facet</em>.</p>
  
  <p>My code is published <a href="https://github.com/shybovycha/irrPaint3D" rel="nofollow noreferrer">on Github</a>.</p>
  
  <p><strong>The question is:</strong> how to split the mesh into charts using the seams generated by the first step of an algorithm?</p>
