title: What's the de facto standard of triangle winding direction in OpenGL?
body: <p>We have two options in triangle winding direction, </p>
  
  <ol>
  <li>clock-wise</li>
  <li>counter-clockwise</li>
  </ol>
  
  <p>Anyway converting between them could take some cost. I want to avoid conversion as much as possible, and to do that, I need to know de facto standard of winding direction. I think there's one because many big corporations are using OpenGL, and I think if there's one direction which is used by most of them, that's de facto standard.</p>
  
  <p>If there's no such thing, please let me know.</p>
