title: How to create a transparent glass cup in OpenGL ES/OpenGL?
body: <p>Is there a way to create a glass cup with OpenGL ES/OpenGl? And if it's possible, what can i read to start creating? Need to get the most realistic view of a glass, for example - </p>
  
  <p>see <a href="http://www.source-werbeartikel.com/produkt/r/RA00022.jpg" rel="nofollow noreferrer">glass cup image</a></p>
  
  <p>For simplicity, without handles.</p>
  
  <p>Maybe, anybody has example with sources?</p>
