title: How can I create and use a Vertex Buffer Object in Pyglet using a Numpy array containing vertex positions?
body: <p>I have a numpy array with sets of vertices for a number of triangles that I want to render. The vertex positions are constantly updated.</p>
  
  <p>The vertices are stored in a numpy array in the following format:</p>
  
  <pre><code>[x1,y1,x2,y2,x3,y3;
   x4,y4,x5,y5,x6,y6;
  ....]
  </code></pre>
  
  <p>Each row contains the vertices for a single triangle.</p>
