title: Opengl es 2.0 3d
body: <p>I am looking for a tutorial about opengl es 2.0 for android,<br>
  until now I have been using andEngine for 2d opengl es 1.x,<br>
  I am looking forward being able to build an app in 3d from scratch, not using someone's engine.<br>
  If its possible, I want the tutorial to explain about 3d textures too, and how to use everything.<br>
  Are there any good tutorials for this?  </p>
  
  <p>I am new to OpenGl, but not to the android platform. i had a lot of experience with canvas and andEngine.</p>
  
  <p>Thanks!</p>
