title: Surface mesh from point cloud in Meshlab
body: <p>I have a point cloud of a terrain, and want to generate a surface mesh.  Is this possible to do in Meshlab?</p>
  
  <p>The point cloud is an xyz file that I generated from a raster file of a Digital Elevation Model.  Each point in the point cloud is on an evenly spaced grid in the x and y axis, and at the desired elevation in the z-axis.  There are around 1 million points.</p>
  
  <p>I can open the xyz file in Meshlab and it looks correct, but I haven't figured out how to generate the surface mesh.</p>
