If you don't have an understanding of signed distance fields, https://www.youtube.com/watch?v=8--5LwHRhjk is an amazing demo of their power. There are more videos about the fundamentals of SDFs at https://www.iquilezles.org/live/index.htm

The interesting thing about this paper is that they replace the mathematical SDF with a neural net that computes SDF_NN(x,y,z) => -1/1 and use this as a compression system for mesh based inputs. This feels like a graphical version of the https://en.wikipedia.org/wiki/Hutter_Prize for NN-based text compression.
