title: Removing the Water Tight-ness property from the mesh constructed by poisson reconstruction using Point Cloud Library
body: <p>I would like to generate visually appealing surface reconstruction from the the point clouds.</p>
  <p>I am using point cloud library. I tried creating a mesh using poisson reconstruction method but later found that it gives a water tight reconstruction.</p>
  <p>For example: In my case I have a point cloud of a room</p>
  <p>Using the code at <a href="http://justpaste.it/code1" rel="noreferrer">http://justpaste.it/code1</a> , I was able to get a reconstruction like this</p>

  <p>The above picture has the surface which is covering the top view. This was visualized using MeshLab.
  Then later on the MeshLab GUI when I press points, it looks like this.

  <p>But in the second picture there are points on its surface too(Not clearly visible in the attached picture).</p>
  <p>Can you help in creating a model that has no points on the top and just has the inside structure ?</p>
  <p>Any other suggestions to improve the reconstruction quality ?</p>
