#perlinnoise #arrays #p5js
You are computing the whole vector field every frame even though you only use a fraction of the vectors. Give the perlin noise function as an argument to the vector follow function and compute the flow vector once per particle instead. It should improve your performance significantly and make it independent of the resolution and only depend on the number of particles.
Really great point, thank you.
A minor extra optimisation could be to save the calculated vector in the flowfield array so that particles in the same square can share it, assuming that wiping the array on each cycle doesn't slow things down again.
Hey Emily, I see what you mean here! Nice tip.
There is a lot of empty space that isn't actually touched by any particle, and it would make sense for each particle to calculate the vector of the "cell" it is currently occupying.
I'm confused about one thing though. If the flow vector is only calculated once per particle, it seems like it would become less of a "flow field" and more of individual particles moving along a perlin noise defined 2d path, totally separate from other particles. Is that how you see it? So if two particles are close to each other, it may loose that appearence of a flow field?
Drew André I'm not totally sure, but I'd imagine that all the particles would still behave like they all exist in the same flow field because they all access the same noise space, and the zoff variable would be changed globally. I think.
ill do it soon
I can't stop watching your videos man!
ProCactus Hahaha! Exactly, my man. These concepts and ideas are really interesting - and his energy and enthusiasm reminds me of the "perfect" college professor. Hehe. He's really fun.
I remember 2 quotes: "The secret to creativity is knowing how to hide your sources" and "Steal like an artist". We'll stand on the shoulders of giants! ;)
***** ProCactus Hahaha! Nice! If you guys are on github (which is a must), you can upload your codes there so that we can all learn together. ;) Have fun guys!
Me neither and i have never even written one bit in any Coding Language =)
I KNOW THAT FEEL
Me2 haha
Instead of setting a max speed you could create a viscous friction force so that it's proportional to the particle's speed, that way everything will behave more like a fluid
Just watching some of your older videos Dan. Makes me wish I had you as a comp sci professor in college. I would've loved it so much more
Definitely. It is great he's sharing on youtube too, though. youtube reaches a lot more people and mostly people who are actually looking for content like his. Computer science students often need to take whatever class they're in if they want to graduate so the level of enthusiasm for what is taught tends to be lower.
These are by far my favorite coding videos and are getting me interested again in coding. Thank you for that.
I just found this channel and learned so much already. I think Perlin Noise is my new favorite thing and can't wait to start playing with it!
Awesome! First video of yours that I've seen. I learned a lot. I hope you keep doing these. Thanks for what you've done so far.
Man i love this guy´s attitude and character =). So excited about what he is doing and a real sense of humor!
When your particles 'wrap around', you're giving their position space a toric symmetry. But the perlin noise doesn't have the same symmetry so it will be discontinuous at the boundary of the canvas.
Oh, this is a very good and important point, thank you!!
I love these videos - don't change a thing!
Is this why the particles are getting stuck at the canvas border?
"Ugh you're back, great!" gotta love Shiffman
I'm feeling so pleased with myself right now, because I followed through the first two thirds of the tutorial and then took it from there and came up with a lot of Dan's solutions by myself. I feel like a big boy who just used the toilet without any help for the first time.
This is really good stuff man.
I'm an accounting major but can't seem to stop watching your videos even though I understand absolutely nothing. Great work.
Hey Dan! I like watching all your videos and wish I had a teacher like you at my University. You explain the most convoluted of things in a very fun and easy way. Taking them part by part. I am really thinking of applying for the Masters program at NYU after watching your videos.
This is the most beautiful thing I've seen this day, shame on me that I haven't checked all of the coding challenges yet..
Was looking for inspiration for generative art for pen plotting and this video is still useful, 6 years later. Thank you!
dude you are blowing my mind
This is the funnest code-related channel out
Я не знаю английский, но преподаватель настолько экспрессивно рассказывает, что становится понятно. Спасибо! Это очень круто!
Thank you very much for this series! You are a very talented teacher
+Stephen Walsh thank you for watching!
This was my favourite illusion yet! This would look so cool if it were a candle blow out animation. You should keep it exactly as is but delete (or let the alpha fade out over time) previous points so that it creates a more dynamic smoke effect!
I swear to God I want that t-shirt so bad hahaha. You're always so fun and interesting to watch, keep up!
I like the video as fast as my cursor can get to the button. Succinct as always. Thank you.
thanks a lot for such amazing stuff... looking forward for upcoming videos
Thanks for watching!
Just brutal watching this guy fumble and stumble over text that brackets his life.
That is sooooooooooo cool !
25:42 the people laughing in background feels like he is doing a comedy skit.
Nice video.
Optimization tip: You can create the paths with moveTo() and lineTo() (or with the line() function you are using) inside the for cols and for rows loops and then draw them with stroke() afterwards, outside of the loops; this will render it much faster - by rendering all the lines once instead of for each line.
Bear in mind it will be a continuous line, so you will have to use moveTo to take the 'pen' off of the canvas and put it to the next line position. moveTo(xa,ya) e.g. 0,0 lineTo(xb, yb) e.g. 0,1 then update xa,ya and xb,yb with the next line positions inside the for loops and repeat. The call stroke() outside the loooops.
I like you. You make your code big enough, so even with a resolution of 144p i can still read it.
I know, i should get faster internet. But it is so expensive!
Wow, that's dedication... I couldn't bare to watch anything in 144p :)
salle rc Yes. But imo it is not worth 50$ a month more just to watch them in 360p...
Michi Lo Ah I see. That's expensive, where do you live?
salle rc Germany. Bavarian Forest. Nowhere near other civilisation.
Didn't realize it's that expensive in Germany, but guess the "nowhere near civilization"-part has something to do with it :) You should move to Sweden, I pay like 15EUR/month for a 100MBit connection.
Thank you, great video
I don't know anything about programming, but stil I'm watching your videos, because you're so excited about it. 😅
Philip Merian Why not start learning now? Daniel has a ton of great videos for beginners!
@@JesseUnderscoreMartin Yea i agree Rebnoz should learn coding! Its not hard and is more than good to learn!
You are so awesome!!! And I'm not even learning or using JavaScript!) might try to apply some of your challenges to Java, but not sure still if will be able to)
0:06 omg nice, this looks great
:D
learn a lot, thank you !!!
looks good
hello there
That is a really nice program. Good job mate.
Thank you!
I have a question, I want to build a Indie game, with sound, and good graphics, and I want to code the whole engine myself, not use unity or anything, what language should I be using for such task? It's a Puzzle Platformer, and some creature like enemies will be in the game.
Ok this was amazing
really impressive
excellent work
I can't get over the fact that there are random sitcom laughter clips playing in the background at some points of the video lol
Thank You! Great video. Fortunately, I didn't have these performance issues... Was running it on 1920x1080 at 5 particles and got stable 80 fps!
I was running in 4k with half a particle, same with me! , no lag at all..
I went back and watched them. Now I'm here.
omg! you're awesome!!!
Thanks for watching!
It's bunch'a cool stuff!
"There's a bunch of few different things" xD
Thanks a lot
Not sure if someone has said this yet, A problem that I've seen is that when you draw the line from prevPoint to pos, there's some overlap of the lines, which if you're using alpha will produce circles at each of the points where the line is drawn. If you have a maxspeed which all of the particles reach, they end up creating dots at a uniform distance from each other.
A fix that I think works is to add "strokeJoin(MITIR)" which makes all of the points at which the strokes join a flat line instead.
+Danial Shiffman Love the videos. I enjoy following along using processing and learning a bunch including the converting from P5 to processing.
Daniel, I must thank you and CZcams's new algorythm for recommended videos. Although I have some knowledge of Arduino and Python, this is the more interactive environment I want to have when coding(Battleship, Conway's game of life aren't that fun using print() in Python lol). Now I'm going to start watching your Processing playlist. Thanks, your videos are really nice to watch.
So glad to hear, thank you!
Juan Fernández try JavaScript learn native first then go to p5 for game development
Hi Dan.
First of all, I love your videos. They really brought me to Processing and I became kind of obsessed with it. :) I really appreciate relatively simple code and outstanding results!
But to this very coding challenge. I believe there's a bug in your edges() function (if not, please someone correct me). I am probably more unlucky than you were when you ran your program and my particles tested the edges to the limit. :)
Your particles are allowed (due to edges method implementation) to have *y* values in a range ** (including border values. This was causing IndexOutOfBoundException when one of the particles was right on the edge (had y = height). In those instances the formula for flowfield's index (*x + y * cols*) gave invalid index. For example (pseudocode)
size(400, 400);
scale = 20;
rows = cols = 400 / 20 = 20;
flowField.length = 400; // index in the range from 0 to 399
particle = new Particle(200, 400);
// particles coors in the grid
col = 200 / 20 = 10
row = 400 / 20 = 20
index = col + row * cols = 10 + 20 * 20 = 410 => invalid index
So the edge() function should be
private void edge() {
if (position.x < 0) {
position.x = width - 1;
}
if (position.x > width - 1) {
position.x = 0;
}
if (position.y < 0) {
position.y = height - 1;
}
if (position.y > height - 1) {
position.y = 0;
}
}
Keep those videos coming, they are really fun and full of brilliant ideas. Thanks!
love how detalied the tutorial is haha
The crux.
Such a great word.
cool you could use this to tell the particles to carve values off of a heightmap over time.
The way the particles are limited with a maximum speed reminds me of how light is limited as the object with the maximum speed in the world.
Wow! 🤩
I got wayy into optimizing this. I can simulate 50 000 particles for 500 iterations in a second. The color of the traces can be dynamically changed. Thinking of making a video of it at some point.
Would be great to see that video and code.
This is so rad. I'm loving your books Dan.
Thanks for the nice feedback!
Love it!
Even though what you did in the end was pointless
Thanks a lot :-)
Now i make beautifull pictures in Java.
That's a nice playground.
Your awesome
thanks 😘
You could also give a velocity to each vector by giving a w to the perlin noise and using it as a velocity
Im the only one hearing those creepy laughs ?
AHHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHAHAHAHAHAHHAHAHAHHAHAHAHAHHAHAHAHAHAHHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHHAHAHAHHAHAHAHAHHAHAHAHAHAHHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHHAHAHAHHAHAHAHAHHAHAHAHAHAHHAHAHAHAHHAHAHAHAHAHAHAHAHAHAHAHAHAHHAHAHAHHAHAHAHAHHAHAHAHAHAHHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHHAHAHAHHAHAHAHAHHAHAHAHAHAHHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHHAHAHAHHAHAHAHAHHAHAHAHAHAHHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHAHAHAHAHAHHAHAHAHHAHAHAHAHHAHAHAHAHAHHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHHAHAHAHHAHAHAHAHHAHAHAHAHAHHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHHAHAHAHHAHAHAHAHHAHAHAHAHAHHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHAHAHAHAHAHHAHAHAHHAHAHAHAHHAHAHAHAHAHHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHHAHAHAHHAHAHAHAHHAHAHAHAHAHHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHHAHAHAHHAHAHAHAHHAHAHAHAHAHHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHAHAHAHAHAHHAHAHAHHAHAHAHAHHAHAHAHAHAHHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHHAHAHAHHAHAHAHAHHAHAHAHAHAHHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHHAHAHAHHAHAHAHAHHAHAHAHAHAHHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHAHAHAHAHAHHAHAHAHHAHAHAHAHHAHAHAHAHAHHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHHAHAHAHHAHAHAHAHHAHAHAHAHAHHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHHAHAHAHHAHAHAHAHHAHAHAHAHAHHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHAHAHAHAHAHHAHAHAHHAHAHAHAHHAHAHAHAHAHHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHHAHAHAHHAHAHAHAHHAHAHAHAHAHHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHHAHAHAHHAHAHAHAHHAHAHAHAHAHHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHAHAHAHAHAHHAHAHAHHAHAHAHAHHAHAHAHAHAHHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHHAHAHAHHAHAHAHAHHAHAHAHAHAHHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHHAHAHAHHAHAHAHAHHAHAHAHAHAHHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHAHAHAHAHAHHAHAHAHHAHAHAHAHHAHAHAHAHAHHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHHAHAHAHHAHAHAHAHHAHAHAHAHAHHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHHAHAHAHHAHAHAHAHHAHAHAHAHAHHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHAHAHAHAHAHHAHAHAHHAHAHAHAHHAHAHAHAHAHHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHHAHAHAHHAHAHAHAHHAHAHAHAHAHHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHHAHAHAHHAHAHAHAHHAHAHAHAHAHHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHHAHAHHAHAHAHAHAHAHAHAHAHAHAHAHAHHAHAHAHHAHAHAHAHHAHAHAHAHAHHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHHAHAHAHHAHAHAHAHHAHAHAHAHAHHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHHAHAHAHHAHAHAHAHHAHAHAHAHAHHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHAHAHAHAHAHHAHAHAHHAHAHAHAHHAHAHAHAHAHHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHHAHAHAHHAHAHAHAHHAHAHAHAHAHHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHHAHAHAHHAHAHAHAHHAHAHAHAHAHHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHAHAHAHAHAHHAHAHAHHAHAHAHAHHAHAHAHAHAHHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHHAHAHAHHAHAHAHAHHAHAHAHAHAHHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHHAHAHAHHAHAHAHAHHAHAHAHAHAHHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHAHAHAHAHAHHAHAHAHHAHAHAHAHHAHAHAHAHAHHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHHAHAHAHHAHAHAHAHHAHAHAHAHAHHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHHAHAHAHHAHAHAHAHHAHAHAHAHAHHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHAHAHAHAHAHHAHAHAHHAHAHAHAHHAHAHAHAHAHHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHHAHAHAHHAHAHAHAHHAHAHAHAHAHHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHHAHAHAHHAHAHAHAHHAHAHAHAHAHHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHAHAHAHAHAHHAHAHAHHAHAHAHAHHAHAHAHAHAHHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHHAHAHAHHAHAHAHAHHAHAHAHAHAHHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHHAHAHAHHAHAHAHAHHAHAHAHAHAHHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHAHAHAHAHAHHAHAHAHHAHAHAHAHHAHAHAHAHAHHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHHAHAHAHHAHAHAHAHHAHAHAHAHAHHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHHAHAHAHHAHAHAHAHHAHAHAHAHAHHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHAHAHAHAHAHHAHAHAHHAHAHAHAHHAHAHAHAHAHHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHHAHAHAHHAHAHAHAHHAHAHAHAHAHHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHHAHAHAHHAHAHAHAHHAHAHAHAHAHHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHAHAHAHAHAHHAHAHAHHAHAHAHAHHAHAHAHAHAHHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHHAHAHAHHAHAHAHAHHAHAHAHAHAHHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHHAHAHAHHAHAHAHAHHAHAHAHAHAHHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAH
No you aren't
i think they are having party next door.
All my Simplex Noise Flow Field creations as CodePen TV: codepen.io/tv/Dwgqqd
awesome work!
I was trying to figure out a way to make the smoke like lines fade over time, and I'm not really a programmer, so I'm really just spitballing here, but one option might be to have the smoke draw on a transparent white layer that also draws every time the program draws. So every time it's adding a bit of white to everything that wasn't just drawn, eventually making old lines fade out. There's probably a better way to do it, and I'm not sure if my way would even work.
even i really like what's going on here i kinda wondering what happening next room, must be something really funny :)
I think the previous position is always the same position as "pos". In the 'update' function, you should apply 'updatePrev' before adding vel to pos.
where is this video on wind flows based on geo locations! !! Dying to see this!
You could use the Simplex Noise algorithm its more effcient and does the same thing.
Okey I liked
Very cool effect. Have you considered doing a coding challenge based around a Navier Stokes fluid solver? Those seem quite similar to the flow fields you’re demonstrating here, however you can have the fluid (equivalent to the particles in your example) affect the flow field - similar to real fluids, rather than relying on Perlin noise to drive the field.
My apologies if you’ve already done this in another video - I couldn’t find one with a quick search.
I have not but this is a great idea!
Might be a nice screensaver
Yay we drew the hairs in the drain!
25:00 the force is strong with this one
Top Notch
n dimension Perlin noise = the sound of minds being blown right now
Thank you soooo much!! I really like Perlin noise! And I tried to follow the processing you upload in the Github...Can I ask why the effect is different from the version of p5js? sorry about the stupid question, I am just the beginner...
8:57
you are a great loving tecaher Daniel :)))
do you do these tutorials for the processing version? because i want to start learning processing more but most of the interesting projects are on p5js
This was Uploaded on my birthday, Man... June 27th is an awesome day
+Toby Brooks happy belated!
Thanks Dan, and Thanks for the Great Video !
Toby Brooks we share the same birthday.
Thank You for this wonderful and educational video! I am a beginner to drawing but a syntax enthusiast, as it helps me to learn sustainability. Would be nice to go through the JS syntax whenever there are more then one-two lines of codes.

Jesus Christ Lol ur the best
WOW
There's a typo in your github code for this project, in the flowfield class.
void update() {
float xoff = 0;
for (int y = 0; y < rows; y++) {
float yoff = 0;
for (int x = 0; x < cols; x++) {
float xoff = 0 is resetting the y loop, and vice versa. (Processing version)
I love your videos! But here I am struggling trying to decode your code from P5 to P3, any tips? I couldn't find a challenge done on P3!
21:20 for a second i thought hes not wearing pants
Oslo Cloonson Yep, I did a double-take too. Deception 100
And remember kids: Shiffman is a particle
when the particles wrap you're updating their position before you set the previous one
we know we're like 6 years late but just fyi
I can't seem to find the processing version on github, have you upploaded it?
You should have names the edges function border control :P
Luca Muscat clever
Or “portal control” since they are teleporting to the opposite side.
@0:38 the good feeling when u really do it..
i like your videos man , but i am too busy with with c++, can i do this in c++ ? i do plan to learn JS in the future
i challenge you make random moving particle and make attraction each other like gravity
webassembly to the rescue
Mind Blowing . Here, particles follow flow flied (i.e : flow flied can be considered as path). Currently, Flow flied is generated using noise. Imagine, there is start point and destination point for a particle. Particles need to reach the destination using generated flow flied... In each iteration, we can alter the flow flied based on the feedback obtained from particles colliding the obstacles(boundaries) then we would have achieved kinda very basic autonomous driving ... Correct me if I am wrong
Isn't it better just to look up the noise value per point, then you don't have to look for the closest vector.
But i do think that this would be worse with a huge amount of particles
Hi, Dan. Could you do a short tutorial on how you set up your local server? Maybe just a quick few minutes at the beginning of the next stream? Thanks a lot!
take a look at: czcams.com/video/UCHzlUiDD10/video.html
Brillinat, thanks so much!
Hey! Quick question, is it possible to tie the flow fields speed to a microphone input?
Marcello30able Anything is possible. forum.processing.org/one/topic/how-can-i-detect-sound-with-my-mic-in-my-computer.html
i like your videos, but preview of your finished work could be longer, because right not it to short i think.
