Am new to mesh formation and using meshlab application. Am currently facing an issue in creating watertight mesh in meshlab. It would be helpful if anyone address this issue.
The surface mesh in your file is too noisy to be useful for any measure. I have reconstructed a much better surface from the same point data using the filter "Surface reconstruction: Ball Pivoting", where you can clearly see the 3 flat layers of the data.
If your purpose is to measure the volume of the data, I would just take measure of the data (size of each layer and distances between layers) and then compute the volume as the sum of the two truncated pyramids.
