<p>my task is to create a watertight surface out of a point-cloud (It's the model of a dam).
For this I'm using MeshLab.</p>

<p>First thing I did was importing the .ply-file into Meshlab and normalize it.</p>

<p>This looked like this:</p>

<p>So far so good. For Remeshing and creating the surface I wanted to use Poisson Surface Reconstruction.</p>

<p>I tried different parameters but this is my best result:</p>

<p>As you can see it creates some weird bubbles in the lower right part of the model.
And I can't figure out why this happens when the rest of my model gets modeled in the way I want it to be.</p>
