Perlin Noise in p5.js

The fact that's someone with your knowledge and intellect would simply give us this knowledge with a smile an an incredible energy goes to show that the world is a good place.

Well, I think it's more the God who made the world that's good, the world itself is still a work in progress!

I just fell here, without any understanding about the subject, and I understood everything. Thank you so much, simplifying is one of the hardest things to do - you did it!

[@graydhd8688]

"I'm dividing it by half", so, you're doubling it? Lol, much love for your videos. Getting into programming and finding your channel has me excited about brushing up on my math skills I haven't used in 10 years

[@tiopetinho]

He's just so excited about Perlin noise, it's contagious. It's really sweet.

[@milestincknell8889]

Your knowledge and energy is off the scale! Loving this a lot, and looking forward to more!

[@CamilaHernandez-um6on]

I am very grateful and happy that these tutorials exist. I study arts and when I met Processing, I knew I had to use it as a tool for a work of art. thank you so much :)

[@nicktailor8062]

Dude I'm a game dev student at uni, always trying/looking for new languages to learn. I found your sfml videos soo helpful for my first year and somehow you're always popping back up whenever I try learning something new! its great since you're such an excellent teacher! Keep it up! really appreciate the hard work you're putting in

[@konfuzius7743]

hey, i know im a bit late, but the way you explain it and manage to mix in the humor is really awesome thank you for the knowledge and the laughts i got from this vid

[@arkondigital1496]

Always grateful to see a great teacher explaining complicated things in so much more understandable ways

[@AhmadAlMutawa_abunoor]

I watched the 2:30 hours version before this. You are awesome. Keep up the good work.

Wow. This is one of the best videos I have seen on a coding topic...ever. Can't wait to watch more.

You are one of the most energetic people I have seen in a while.

[@mightfloat9365]

You're the only teacher that made me understand this concept. Thank you!

[@catlord69]

wow, this idea is brilliant ! Imagine you work on a movie and someone requests "random shapes". You think about it, make an algorithm as best as you can...and then win a huge prize, because you invented something so inovative

[@souvikroy6237]

I am addicted to your teaching style ♥️

[@ugy2]

Great series! With an awareness of how pedantic this is: if you divide by half, you double!

[@goldthumb]

Daniel is a true expert in explaining things.

[@skullaveraz]

hahah dude, you're a genius with the sense of humour to boot! Love you videos!

[@Jilinhall]

this is actually such a smart way to generate a random but smooth-ish curve!

[@thatrealguylogan]

wow, this video is great because of your personality and energy, it make the video less of just normal tutorial and more of a conversation and because of that it is very easy to learn and catch on to things, so thank you this helps a lot!!!

[@MrBmxerFTW]

when i discovered processing/cinder/OF I knew i had to use it for design, thanks for sharing your knowledge

wow, I created my own noise a few years ago when I was 12, and it's basically perlin noise.

The start of the video was basically Dan saying how bad his art is while trying to draw stuff and i love it

[@devendradhakad6164]

thank you sir for this tutorial .... i'm from india 🚩❤

[@DevDungeon]

Beautiful explanation! I didn't realize it was so simple.

its not lmao, he didn't explain the entire thing..

And how I seriously want him to do a perlin noise performance video is just hilarious

[@jennifer7chan]

That tron from 1986 is amazing. every scene is like a painting.

[@JavSusLar]

Actually 1982. Jeff Bridges is the main character!

[@donatellobruno]

I love this. Thank you so much for all your videos Daniel!

i love the tron movies, great video series dan!

[@jorgeferreira6727]

Something about this Perlin noise explanation made remember the Fourier Transform on periodic signals.

[@geckobra]

I heard about perlin noise when I was watching minecraft videos. It is very interesting to learn what it is :DD

[@LoadNewYear]

If this guy was my teacher, I'd go to school even on sundays.

I just get into this topic that I am start thinking I am superlate. Good to know this. Thank you I will sucscribe your video.

Yes, although it's really just a small group of volunteers: processingfoundation.org/

[@JavSusLar]

1:31 as a matter of fact, TRON wasn't even nominated in the Best Visual Effects category. Academy members considered they were cheating because they used computers. Clairevoyants... (Perlin received the Oscar in 1996 for the technical achievement, but the film never did)

But what's the reason that Perlin Noice is so important that you willing to make a bunch of videos around it? Or just for fun haha. And much thanks for all of those videos : ) their influences are propound. I built almost all of my p5 skill based on them!

[@ChrispyByDefault]

Great video!

[@TavartDukod]

You are describing fractal value noise (en.wikipedia.org/wiki/Value_noise). Perlin noise isn't fractal by default and is a variant of gradient noise, not value noise.

[@chanasiegel2706]

How is that one dimension? You have Time and the number Value/Range

[@HISEROD]

The noise algorithm has only 1 input; so, it is 1D noise. But, the graph of this noise is indeed 2D. Take the 2D distance function *distance(x, y) = √(x^2 + y^2)* for example. You wouldn't call it a 3D function, but an additional dimension is required to visualize it (2 for the inputs + 1 for the output).

I know I'm super late to the party, but the wuestion is bugging me: a while ago, I saw a video on value noise, and it was descirbed the same way. so, does that mean that perlin noise and value noise are the same?

is it true humans can't pick random numbers?

[@jamestheotherone742]

No the human brain is pretty good at picking random numbers because the "seed" for it is so complex as long as they don't habitually pick a "favorite number".

[@okie9025]

If you ask any human to pick 100 random numbers, most of the time the biggest streak od numbers they have is 3, so no

[@jamestheotherone742]

@@okie9025 Or is it 17? Or 12? Or 7? None of the studies or experiments agree. So, yes. Look! Ask a question in a comments sections and generate a boolean randomizer! ;)

[@clarencesmith2060]

I like your videos. But what you explain in this video is not Perlin noise. It's value noise. Perlin noise uses gradients, and doesn't use cosine interpolation, but linear interpolation in combination with a fade function instead.

[@thorham1346]

Indeed.
