The idea behind this post goes back to a Fractal Forums discussion back in 2012, where Knighty came up with a clever scheme for ray marching polytopes. It also discusses the mathematics behind Jenn 3D (a tool for creating explicit geometry).

Due to the complexity of the post, I did not use WordPress for this. Instead the blog post is hosted on GitHub, and can be found here:
