Voronoi Edges Explained Part 2

If you already understand the basic voronoi algorithm you can start here. Part one explains why I dont use fract(). Otherwise feel free to check out part 1: Voronoi Edges Explained (why you don'...

In this video:
More vector diagrams and code for the voronoi edges algorithm. I discuss other versions you might find and explain why although they might seem different on the surface, algebraicly they are the same. Then I walk through the process of creating the artwork I show in the thumbnail.

In the introductory video:
I do vector diagrams and show the code for a version of the basic voronoi algorithm that doesn't use the fract function. This isn't strictly nessessary for the voronoi edges algorithm. I chose to show this version because it might help people see the math better.

Here is the final code for this project running live on shadertoy:
