title: Efficiently visualise large quantities of points with matlab.
body: <p>I have a set of 3D points which numbers up around 1 million points. I am looking to visualise these with matlab. </p>
  
  <p>I have tried the following functions: </p>
  
  <pre><code>plot3
  scatter3
  </code></pre>
  
  <p>But they are both very sluggish. Is there a more efficient way to visualise this level of points in matlab? Maybe a way to mesh the points? </p>
  
  <p>If not can anyone suggest a plug-in or even a different program for visualising 3D points? </p>
