title: Dynamically render lines between vertices OpenGL
body: <p>How does one efficiently update the vertices between render calls and dynamically render lines between some of these points?</p>
  
  <p>I am working on a basic OpenGL example and it's a static vertices array that renders using <code>glDrawArrays</code> and the <code>GL_TRIANGLES</code> Macro.</p>
  
  <p>I would like to experiment a little with dynamically updated vertices and draw basic lines between random points.</p>
