Textures used in this video:

Noise textures give programmers a way to introduce random and organic elements into their effects. In this video I'll show you how you can use noise textures in a shader to create a simple texture blending effect.
There are so many ways that you can use noise to create awesome looking visuals, so hopefully you find this video useful and pick up a few tricks!

If you'd like to see what else I'm working on, it would be great if you could wishlist my game Star Mining Co. on Steam! s.team/a/2584800/

What shader effect would you like to see next?

Barney at it again!!! 🎉

Wow I used to think generating noise in code is more efficient. But using a texture for it comes as a surprise man. Thanks :)

Really great explanation. I love the way you go through this, showing all the code changes and variants! Top notch editing. Thanks man!

0:08 it looks like a shader that replicates how cells look like. Every "cell" (circle) is separated from adjacent circles but all of them are together, on a similar way how skin cells would be (or any kind of large cell structure really)

Thanks for the video. Really well explained.
3:38 The thing with p5.js is that the coordinates 0, 0 are located in the top left corner instead of the bottom left.
