Voronoi Edges Explained Part 1

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: • Voronoi Edges Explaine...
Code is linked in the second part of this tutorial.

Part two, "Voronoi Edges Explained" Is posted now!

[@acidangel162]

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

[@daxtron2]

Tony's?

[@acidangel162]

@@daxtron2 Tony's what? I live in Finland Europe. I doubt that we have the same chocolate brands as you.

[@Yusef28]

Wow, I knew voronoi was used in lot's of industries but I haven't come across it in food. Thatt's neat!

[@a_soulspark]

@@acidangel162 Tony's Chocolonely, it's a Dutch chocolate brand which has a Voronoi-like division on its chocolate bars (and pretty tasty too!)

[@acidangel162]

@@a_soulspark That's a pretty cool looking bar but it was some other brand. Our shops do carry that though. Might give it a go.

[@Newemka]

I'm looking forward for the next part!

[@Yusef28]

Thanks, glad to hear it!

[@lifelover69]

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

[@Yusef28]

I'm glad you found the explaination thorough, I'mmaking sure part 2 is the same!

[@cours458]

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

[@Yusef28]

I'm glad to hear that, thank-you!

[@sentinelav]

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

[@Yusef28]

Thanks for the feedback, I'm switched the genre for something classical so hopefully it's an improvement

[@hazilo]

@@Yusef28 Still way too loud...

[@Yusef28]

@@hazilo Thanks for letting me know, I thought I adjusted it properly but looks like it didn't save the change. Should be updated soon!

[@AnnonymousPrime-ks4uf]

Ah my guy. It seems we are one lol...

[@prashanthkumar0]

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

[@Yusef28]

It looks like it either didn't save my edit properly or I made a mistake there I'm working on that now. Thanks for the tip!

[@yitz7805]

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

[@Yusef28]

Thanks, I'm working on that now, should be updated soon!

[@Manu-lc4ob]

KZbin algo knows me well. Subscribed !

[@Yusef28]

Yup I can't complain about the algo, it's been showing me a lot of really awesome content recently!

[@neon_Nomad]

I randomly started working with caternary curves

[@Yusef28]

Oh do you mean like the parametric pavillion, those look really cool!

[@MohamedIbrahim-go4mg]

great work!

[@Yusef28]

Thanks!

[@Byron_Vega]

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

[@Yusef28]

Hi, I'm glad you found a verison without fract helped make things make sense, That's greatfeedback, thanks!

[@jakeaustria5445]

Thank you

[@Yusef28]

I'm glad you found it useful!

[@ShaggyMummy]

Voronoi is my Favorite noise pattern to use in Blender

[@Yusef28]

Nice! It's a beautiful pattern.

[@apppples]

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

[@Yusef28]

Thanks @apppples, I'm working on that now, should be updated soon!

[@gwentarinokripperinolkjdsf683]

Thanks for the music lmao

[@jhonbus]

Couldn't watch it lol

[@Yusef28]

I've been getting some mixed feedback on the music so I'm trying another genre
