The meshing is done with custom software, using the Gubas-Stolfi Delaunay triangulation algorithm. More details on the GitHub page, the code is free and open-source: github.com/alex-petrenko/4dvideo
It's uploaded as a "timeframe animation" format. Basically, I used a separate .ply file for each frame and one metadata file that specifies the duration of each frame. I believe there's a Sketchfab documentation page about this. The C++ code contains functionality to export in this "timeframe animation" format.
I don't know what Alembic is. Not sure about point clouds either. Is it possible in general to upload a point cloud to Sketchfab? If yes, then I think it's entirely possible to upload point cloud animation too.
Soon we will also limit each existing Sketchfab scene to one category, so pick your category carefully. You can use tags to further classify your model.

@3Duae mind, this is across all frames in the animation. It is only several thousand per frame.
5M Triangles !!!!

@apetrenko1991
how did you did the meshing (convert the pointcloud data to mesh)?
and how did you upload it here?
did you used Alembic?
is it possible to upload point cloud in "animated" sequences?
Hey, I removed the categories Characters & Creatures, Fashion & Style and Food & Drink.
