title: How to cut an object using WebGL shaders?
body: <p>I would like to cut an object (a box) in <code>WebGL</code> (<code>fragment shaders</code> / <code>vertex shaders</code>) without using Boolean operations (union, difference, etc..). </p>
  
  <p>I want to use shaders to hide some part of the object (so it is therefore not really a "real cuts" since it simply hides the object).</p>
  
  <p><strong>EDIT</strong></p>
