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?

@Moll-ayyy

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.

"Ugh you're back, great!" gotta love Shiffman

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.

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!

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.

Man i love this guy´s attitude and character =). So excited about what he is doing and a real sense of humor!

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.

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.

I'm an accounting major but can't seem to stop watching your videos even though I understand absolutely nothing. Great work.

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..

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!

This is really good stuff man.

dude you are blowing my mind

This is the funnest code-related channel out

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 swear to God I want that t-shirt so bad hahaha. You're always so fun and interesting to watch, keep up!

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 position.x = width - 1; } if (position.x > width - 1) { position.x = 0; } if (position.y 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!

I was running in 4k with half a particle, same with me! , no lag at all..

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)

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.

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.

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'm confused, can you use function draw() in say notepad, or is it something specifically used within p5?

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.

I can't seem to find the processing version on github, have you upploaded it?

+Danial Shiffman Love the videos. I enjoy following along using processing and learning a bunch including the converting from P5 to processing.

Thank you, great video

cool you could use this to tell the particles to carve values off of a heightmap over time.

0:06 omg nice, this looks great :D

excellent work

You are saying that you have made the Perlin noise program for processing earlier but I can't seem to find it anywhere. I may have overlooked it on github but I think it is not there. Does any one know were to find it?

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 can't get over the fact that there are random sitcom laughter clips playing in the background at some points of the video lol

Thanks a lot

Ok this was amazing

You could also give a velocity to each vector by giving a w to the perlin noise and using it as a velocity

That is sooooooooooo cool !

The crux. Such a great word.

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.

Whats the algorithm for the audio background noise?

WHY it is "createP is not defined"and "particle is not a contructor" keep showing up in my console?

Can you make particle flow but with pressure? That you can't have many particles in one place. I have made something simmilar on mobile- vector array (vector values are based on touch data from the screen) and particles that are appearing in random position when flow outside the screen. It looks cool but without pressure all particles can be squized to 1px space and this looks bad.
