I wrote an article on how to ray march distance fields in concert with rasterization in Unity. If anyone’s interested check it out: http://flafla2.github.io/2016/10/01/raymarching.html

At SIGGRAPH this year, I also saw this raymarching toolkit that takes the idea to a production-ready setting: https://kev.town/raymarching-toolkit/

A cool example of the power of raymarching is the ability to raymarch complex mathematical forms much more easily than with mesh-based methods, and with infinite resolution. Here’s a cool paper on raymarching quaternion julia sets: https://www.cs.cmu.edu/~kmcrane/Projects/QuaternionJulia/
