What is Perlin Noise?

[@akinoreh]

This was surprisingly explanatory. I recently started using perlin noise to generate random path/velocity for moving objects (bubbles). While I kind of made it work, I have no idea how the noise works. This shed some light.

Thank you! Appreciate your support 🫶

Thanks for making this video.
I was struggling with understanding how Perlin noise works, but your video showed it with depth and simplicity.

[@SuboptimalEng]

Thanks, I’m glad the video was helpful!

[@gehtsiegarnixan]

very well explained and visalized thank you!

[@OskarKassander]

Great video and explanation once again!

[@polandsilver3419]

Thank you for this explanation! I'm new into programing (although I programmed in scratch when I was really young). That's realy good piece of knowledge :)

[@SuboptimalEng]

Good luck on your programming journey!

Amazing video! I was waiting for this one

[@meijuta]

it bothers me that the font on the thumbnail and start of video are different

[@tatrix]

Great video!
Why smoothstep/quintic fixes grid like pattern?

[@SuboptimalEng]

Hard to explain the math in a comment. I’d recommend trying out the shader and seeing why it works.

This is similar-looking to diamond-square noise (aka plasma), but very different implementation

[@SuboptimalEng]

@@eitantal726 Interesting I never heard about diamond square noise before. Adding that to my list of topics to study.

thank you very very much...........

[@tortue5080]

nice thanks

[@TheNinjaOfTheGoldenTemple]

more more more!!!

[@iamtufa]

i didnt understand how u got the distance

[@SuboptimalEng]

Code is open source on my GitHub so hopefully you can learn it from there!

[@RujipasThongpao]

​@@SuboptimalEng I think its actually wrong because the distance in your video is uv-direction, which its not the distance to the corer. However, It should be uv-cornor_pos instead
