Since my last enthusiastic photogrammetry post, I moved on to trying some more Meshroom tests. These additional samples revealed some limitation and obstacles that I'll need to learn more about and overcome. The first "rock" test turned out pretty well because I unintentionally adhered to some of the ideal conditions for photogrammetry.
Secondly, Meshlab is crashing my PC. Complete blue screen of death. I suspect it has something to do with with overclocking my CPU, the stock overclock of my GPU, or memory overclocking. I played around with these settings with mixed results about a year ago and never learned enough about what I was doing to effectively tune everything just right for stability. I was regularly crashing PC games back then, then got to a point where it rarely crashed, but never perfect. There isn't a great deal of Meshroom help that I can easily find related to this other than references to removing overclock to GPU for stability. Another area to improve will be learning more about my smartphone's camera. I usually just a point & shoot. I believe there is likely more settings and features available that can result in better photos. More Tests A couple days ago I visited a bodyworlds exhibit. It was a fun trip, and had some really interesting showcases. You can't leave something like that without feeling a sense of mortality and how fragile and complex beings we are. Below are some more 3D photo scanning samples I took at the exhibit, and on a walk afterward nearby.
Skeleton & Brain + Arteries - Again, I had really low expectations with these, but was still curious how Meshroom would handle reconstructing complex geometry with glass reflections and fewer photo angles.
Fire Hydrant, Small Plant (and more not shown) - With these, I took more time to find suitable samples with great lighting, and matte surfaces. I also took several more photos than I did with my first rock test. As well as taking 2 or 3 different 360 degree sweeps, at varying angles. I thought they would yield some high quality geometry. However, I ended up with pretty bad results. The majority of the time, it just caused my computer to crash. Note: The plant I was trying to capture was completely omitted from my generated mesh.
