title: getcontext() with 3D rendering javascript
body: <p>Q.) I have canvas element and i'm drawing with 2D javascript(papaer js) and  3D javascript(babylon js) on canvas. Now, i want to add/draw image on that canvas in 2D and 3D.
  I can draw image on canvas using 2D JS(Paper js).</p>
  
  <p>like this, </p>
  
  <pre><code>var canvas = document.getElementById('canvsID');
  var context = canvas.getContext('2d');
  </code></pre>
  
  <p>and i get the result with that. </p>
  
  <p>i want to do same thing with 3D JS. But it wont, work with 3D JS.
  it is just because my 3D js is continuously rendering. </p>
  
  <p>So, is there any way for that.</p>
  
  <p>I read that you can use getContext() with 3D like this..</p>
  
  <pre><code> var context = canvas.getContext('webgl');
  </code></pre>
  
  <p>But, still it wont work..! It says "WebGL not supported"</p>
