As it has been mentioned in that short introduction, MeshLab compares two 3D models by calculating the Hausdorff distance between them. This option is available under Filters menu (Filters -> Sampling -> Hausdorff Distance). Before applying this filter, you need to open two 3D models in MeshLab and select them from drop down menu in filter options. By default the filter output will be logged in the MeshLab console on right-bottom corner (If it is not visible press Ctrl + L).


You can also compare 3D models in MeshLab by calculating per vertex geometric distance between them (Filters -> Sampling -> Distance from Reference Mesh). The distance will be stored as per vertex quality. You can visualize these distances by enabling Render -> Show Quality Contour or Render -> Show Quality Histogram.


Here is a two part article on the same topic from MeshLab author Paolo Cignoni (Part 1 and Part 2).
