title: creating bounding box around openGL objects
body: <p>I've created an openGL square like so..</p>
  
  <pre><code>            final float array1[] = new float[] {
              //Front face
              lx, ly, hz,
              lx, hy, hz,
              hx, ly, hz,
              hx, hy, hz
      };
  </code></pre>
  
  <p>I've also got a Ray. I'd now like to put bounding boxes around every  square I draw so that I can check if they intersect. How would I go about doing this?</p>
  
  <p>Thanks.</p>
