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.
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.
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.
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
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.
Using a 3d Perlin evaluated on a toroidal surface could potentially help here. Or continuously creating new particles at random locations as particles fall off of the edges.
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 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 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!
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.
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.
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.
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!
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.
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.
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
I do not understand 25:30 - Why do the vectors mostly point toward left? And why multiplying by 4? If noise returns between 0 and 1 and we multiply by 2PI we should have already the correct values... What am I missing?
When the increment variable was set to 1, all the tiles were mid grey. He then changed it to 0.1, and he got more variation, but nowhere near a range between black and white.
Referring to 6:50 I wasn't able to get a new angle to change the vectors. All it displays is the lines shown at 6:45 no matter what I put in p5.Vector.fromAngle(). I have P5 imported correctly. Did anyone else run into this issue?
Would you mind asking at discourse.processing.org/! It's a better platform for Processing and p5.js related code questions. You can share code there easily! Feel free to link from here to your post.
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...
I made some sort of cube that has set length random directed 3d lines in every scl in every axis. I did not use a vector however, but it seems my lines tend to be aligned on a plane. I could post my code here if anyone is interested. I don't think I succesfully made a vector field but I can't really inspect it properly. I think what I made is layers of 2D vector (well they aren't vectors but lines) fields. You also need to download the peasycam library to rotate around. I don't know why I'm writing all this considering nobody cares.
DUDE I MADE IT! It's so damn SATISFYING to see 3d vectors wander over time! I mapped every vector's hue to the perlin noise in its coordinates. It currently lacks particle systems but I think I got this. Not too bad for my first procesing program lol
At around 13:30 of the video, what does the line this.acc.mult(0); do? I know that it is multiplying the acceleration vector by a zero scalar, but what does that actually do?
Yeah, you would have to decrease regularly the pixels' luminosity by drawing a new point over each of them, with the luminosity of the pixel in question minus a certain gradient
i was following along i wrote the code var increment = 0.01; var scale = 20; var cols, rows; function setup(){ createCanvas(200,200); cols = floor(width / scale); rows = floor(height / scale);
} function draw (){
var yoffset = 0; for (var y = 0; y < rows; y++) { var xoffset = 0; for (var x = 0; x < cols; x++) { var index = (x + y * width) * 4; var r = noise(xoffset, yoffset) * 255; xoffset += increment; fill(random(255)); rect(x * scale, y * scale, scale, scale); } yoffset += increment; } yet for some reason i could not get the cubes to show
Can i see the code for the processing version anywere? I tries myself and it works but doesent look as cool as in the version in the video and i want to check whats diffrent Sry for my bad english
Won't run... looked over the whole tutorial, went to your github, getting errors... none of the functions you are calling for particles[i] are recognized...

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?
Using a 3d Perlin evaluated on a toroidal surface could potentially help here. Or continuously creating new particles at random locations as particles fall off of the edges.

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.
You could use the Simplex Noise algorithm its more effcient and does the same thing.

When the increment variable was set to 1, all the tiles were mid grey. He then changed it to 0.1, and he got more variation, but nowhere near a range between black and white.
The values tend to be around 0.5 so if you multiply by 2PI they will tend to be around PI (which is the left direction).

excellent work
I want to do a colorful version in 3d space that rotates around the origin. Welp, time to learn processing.
I made some sort of cube that has set length random directed 3d lines in every scl in every axis. I did not use a vector however, but it seems my lines tend to be aligned on a plane. I could post my code here if anyone is interested. I don't think I succesfully made a vector field but I can't really inspect it properly.

Does this mean processing is way more efficient than P5 ?
How is this possible to export it in SVG file format?
Where's the starting code, I would like to code along.
At around 13:30 of the video, what does the line this.acc.mult(0); do? I know that it is multiplying the acceleration vector by a zero scalar, but what does that actually do?
I cover this in section 2.3 of nature of code! natureofcode.com/book/chapter-2-forces/
Does anybody have the code for the processing sketch?
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
Is there a way to delete the drawn pixels after an amount of time, so you can run an infinite animation and create some kind of "snakes"
Yeah, you would have to decrease regularly the pixels' luminosity by drawing a new point over each of them, with the luminosity of the pixel in question minus a certain gradient
Alternatively, draw over the entire screen with the background color but a very small alpha, so rather than clearing it's fading the old
why do the points disappear over time? I'm at 25:07 of the the video

Your awesome
I'm confused, can you use function draw() in say notepad, or is it something specifically used within p5?
i like your videos, but preview of your finished work could be longer, because right not it to short i think.
"So I'm moving through time a little bit too quickly".
This is a normal quote from a completely normal person that didn't use drugs 10:40 minutes ago
Im new to this, how do I get started? I know some js, but willing to learn more.
8:33 Does The Coding Train have a laugh track? (EDIT: That was not intended as pun.)
i was following along i wrote the code
var increment = 0.01;
var scale = 20;
var cols, rows;
function setup(){
createCanvas(200,200);
cols = floor(width / scale);
rows = floor(height / scale);
}
function draw (){
var yoffset = 0;
for (var y = 0; y < rows; y++)
{
var xoffset = 0;
for (var x = 0; x < cols; x++)
{
var index = (x + y * width) * 4;
var r = noise(xoffset, yoffset) * 255;
xoffset += increment;
fill(random(255));
rect(x * scale, y * scale, scale, scale);
}
yoffset += increment;
}
yet for some reason i could not get the cubes to show
my rectangles have some kind of a freaky shadow on the inside of the right edge.
Can i see the code for the processing version anywere?
I tries myself and it works but doesent look as cool as in the version in the video and i want to check whats diffrent
Sry for my bad english

if u have not watch my videos on Perlin noise , go watch and come back ! In the same line , ha ! u are back!
What am I supposed to not do about it
I change the background to black and the line to red looks like blood vein. Thats cool but i need many time to understand
can you tell me how please?

Won't run... looked over the whole tutorial, went to your github, getting errors... none of the functions you are calling for particles[i] are recognized...
You had p5.js installed, right?
Is this a hair generator?
The background noise is so perturbing
edges function can be simplified:
this.pos.x = this.pos.x % width;
this.pos.y = this.pos.y % height;
