How is it related to ML? Closed form implicit surfaces are actually one of the most difficult way to model the real world. They are neat because they are very compact and the creation process is close to modeling with (mathematical) clay. But they are hard to use if you want to model the real world with all its complexity, resulting of a variety of chemical and physical processes happening over time. There is a reason why they are so popular in the demoscene, for which technical achievement and art is more important than realism, and not much elsewhere. The paper is about making rendering of these primitives more efficient, which may prove to be a great addition to an artist toolbox, and maybe for scientific imagery. However, I don't really see applications for ML anytime soon.
