title: Stream of Cloud Point Visualization using PCL
body: <p>I am doing some processing on RGB and Depth data and constructing cloud points that are to be visualized, I currently use PCL Visualizer and it works fine.
  I want to have the visualizer in a different thread (real time so it will redraw the global cloud point, I tried boost threads but I get a runtime error "VTK bad lookup table"</p>
  
  <p>Anyone knows how to visualize stream of cloud points in a different thread ?</p>
