Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Rendering algorithm used for implicit functions
For constructing the quadtree, I'd refer you to https://github.com/jared-hughes/isosurfaces (specifically build_tree and should_descend_deep_cell) which takes a similar approach as Desmos: descend to a certain depth, say 5 (to get a 32×32 grid), then descend only quads that cross the isoline (with a few more heuristics).

How does desmos render implicit plots?
Desmos uses the same approach as my isosurfaces Python package, based on J. Manson and S. Schaefer, "Isosurfaces Over Simplicial Partitions of Multiresolution Grids."

Hip implant modeling
All that said, there is a GitHub project that comes up in a rudimentary search, using Python to convert the file to separate STLs for each ‘layer’. This isn’t an endorsement, just acknowledging it exists. https://github.com/dave3d/dicom2stl
