Thanks very much! I use Polycam on iOS for photogrammetry and generating Gaussian splats from stills. It seems to work remarkably well, but has a subscription fee (given there's processing on their servers this seems reasonable). Typically to build a splat model takes about 30-50 stills for good results, depending on the subject.

The only open source tool I use in my workflow is CloudCompare (https://www.danielgm.net/cc/), for editing/cleaning point cloud data.

For animation I primarily use Touch Designer which is a node based visual programming environment, exporting splats as point clouds, and Ableton/misc instruments for sound.

No idea about web visualisation, but interesting idea!

Have you tried Kiri Vs polycam?

I was using kiris dev mode and then running that through nerfstudio to make nerfs and I'm wondering if polycam might give higher quality but I can't seem to find anyone else whose been doing this. I guess I might have to do some tests to compare.

+1 to this workflow. TouchDesigners point transform TOP is great for aligning too.

No afraid not sorry, I've only used Polycam. TouchDesigner is such a pleasure - I can't remember when I last found creative software as fun and interesting to explore.
