@skepteis Yep meshlab was what I was interested in, thanks. Just a passing curiosity as my last "scientific" foray included creating and visualising similar structures. Well, not really in terms of subject, but in terms of visualisation (that were generic structures trying to mimic snow microstructures, where I used pyvista/VTK for viz).
@skepteis Nothing online. My supervisor was talking about publicating something for quite a while, but it never happened. Not too unhappy given my code "quality" as I remember it. Just dug up the old files, and also comparing the visualisations to yours is... a stretch to put it mildly, as you can see :) The cool viz. in my group were time-series of CTs of real snow - though the examples here aren't that great quality: https://www.slf.ch/en/snow/snow-as-a-material/snow-metamorphism.html
Snow metamorphism - SLF
Snow metamorphism transforms the structure of fresh fallen snow within a very short time. We are able to observe and measure these changes.
@skepteis Thanks. I know - I was quite surprised when I checked out when "publication" got first mentioned as a possibility. However I switched careers, code quality is now what it all is (or at least should be) about :)
