Meshlab creates weird bubbles when using poisson surface reconstruction 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.

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

This looked like this:



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

I tried different parameters but this is my best result:



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.

Thanks for your help!
Solution: After trying a lot of different filters with different tools, I came up with simplifying the point-cloud. After that, using the poisson surface reconstruction filter worked just fine without creating any weird bubbles.
