title: how to create a 3D height map in python
body: <p>I have a 2D array Z that stores the height at that element's position. Other than using the method <a href="http://matplotlib.org/mpl_toolkits/mplot3d/tutorial.html#surface-plots" rel="noreferrer">here</a> in which I need to create array X and Y with the same size as Z, are there any simpler methods to create a 3D height map?  </p>
  
  <p>The 3D surface height map is something like the first surface plot <a href="http://uk.mathworks.com/help/matlab/ref/surf.html" rel="noreferrer">here</a>. </p>
