title: 3D Pointcloud Plot
body: <p>got some Issues here, I do have Coordinates in lists. These coordinates are from a Laserscanner, which scans in layers, so finished one layer it gets to the next, this is were the indicies and nested lists come from. The single lists for X Y and Z are 720 indices long. And the descriebed earlier nested lists for every indice are representing the layers. This gives me a Structure like shown here: </p>
  
  <pre><code>len(X) = 720
  X[1] = [ 0. 8.62348279  ... 9.10556606  9.15339632  9.11527918  9.11995584]
  </code></pre>
  
  <p>What did i try until now? </p>
  
  <p>I did try to plot this Stuff as a Scatterplot, which works quite fine. </p>
  
  <pre><code>fig = plt.figure()
  ax = fig.add_subplot(111, projection='3d')
  for i in range(len(X1)):
     plt.scatter(X1[i],Y1[i],Z1[i],marker='x')
  plt.show()
  </code></pre>
  
  <p>Now on to my questions:</p>
  
  <ol>
  <li>The ScatterPlot, which you see implemented above shows the points in
  a strange "gluLookAt" condition, my first question is how to manipulate
  the Look At Angle or Position. So I´m watching the Plot like I´am in the
  Position of the scanner, or a bit above.</li>
  <li>How can I plot the single Layers in different colors, there are 24 Layers
  for one scan circle. </li>
  <li>In addition to show how the scanner works, it would be nice to have an 
  animated scan profile, so every layer get´s scanned one after another.</li>
  </ol>
  
  <p>I hope you guys can help me again, Thanks in advance.</p>
  
  <p>Best regards </p>
