    What MeshLab version are you using and what is your meshlabserver command? I would guess that you are outputting the wrong layer; you may be outputting the first layer (the original file) instead of the second. Try adding a delete layer filter at the end of your script.

    That's quite interesting. It's difficult to see the traingulation in the first mesh, can you please turn diplay edges and/or wireframe on? It would also be helpful to see what the original mesh looks like, or even better, provide a sample mesh that exhibits the issue.

    In the compute.py module, see the functions parse_geometry & parse_topology.

    I will try to squeeze it in if I can, but honestly I'm completely swamped at the moment. If you know Python (and you must, in order to use MLX) then you could write a parsing function yourself. That's the beauty of open source, right? If it helps, you can look at how I currently parse the geometry and topology info in compute.py.

    Mohammad, Unfortunately I can't think of any other options other than the two I mentioned: either section the models and measure each section separately, or measure the entire model and section the results afterwards. It sounds like you wish to pursue the second option, which entails extracting the geometry and quality values from a ply file. There are other libraries that can read ply files, such as PyMesh for Python, and others for different languages, however I'm not sure that they will all read...

    If I'm understanding correctly, you just want to compute the distance over a portion of the mesh, not the entire mesh, correct? Here's one possible way you could accomplish this with MeshLab: Write a selection function to select vertices in your section of interest, i.e. select any vertices that are within certain x, y & z values. Invert the selection & delete. Essentially you are cutting out your section of interest. Repeat on the second mesh. Compute the Hausdorff distance between the meshes and...

    The max, min & RMS distance values are reported in the log window in the lower right (make sure that the layer dialog is turned on). The filter also creates vertex quality values, which are the computed distance values. If you haven't already, you may want to review this article: http://meshlabstuff.blogspot.com/2010/01/measuring-difference-between-two-meshes.html If you are trying to access the raw distance values, I think you would need to save the mesh in ply format, with the vq values, and extract...

    Sounds like you are looking for "Hausdorff Distance" under "Sampling".
