If you are new to the procedural voronoi algorithm or you just want to see a deep explainatin including how it can be done without using fract() then this is for you!

In this two part video tutorial you will learn how the procedurally generated voronoi and voronoi edges algorithms work. With the help of intuitive diagrams, glsl code walkthroughs, and some quick vector math explainatins you will come away with the confidence to use these techniques in your own shaders. As a bonus you will also be introduced to some techniques for creating beautiful art work based on these voronoi algorithms.

Part 1/2:
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 you understand what is happening mathematically.

Part 2/2:
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.
Part 2: • Procedural Voronoi Explained

Code is linked in the second part of this tutorial.

Voronoi patterns appear in the most random places. Yesterday I ate chocolate that instead of a grid was broken into a voronoi pattern.

I'm looking forward for the next part!

very cool and thorough explanation, i love playing with voronoi in blender :)

Thank you so much for making this video, the frac implementation never made sense to me <3

you modelised the patterns that appear in acrylic paint "pouring" which I love, that's cool

Youtube algo knows me well. Subscribed !

Great video, but the music is pretty loud compared to the voice audio, making it hard to understand you at times.

I appreciate heavy dnb as much as the next fella but I'm not sure if it suits the context my guy 😆

Good content... But background music in middle was little loud than voice

I randomly started working with caternary curves

Voronoi is my Favorite noise pattern to use in Blender

Thanks for the music lmao
@apppples hace 10 días

music is a bit loud, it should be quieter than your voice. background not foreground

The pronunciation of "voronoi" bugs me to no end... XD
