awesome tutorial. Processing is still relevant 9 years later !

I found this video at the beginning of the pandemic and it reinvigorated my passion for generative art. I just want to say that I really appreciate you taking the time to show us something that inspired you because in doing so it inspired us.

[@AbishaiC]

In case this comment section is still interested, there is an entire set of programs related to parametric design developed by Robert McNeel called "Rhinocers" and the parametric part of it is called "Grasshopper". Its a sort of visual coding that i'm sure you guys will love to check out. Great video though, cheers!

[@future_finno5352]

where to find tho??

[@DavidDaybreakASMR]

I'm learning Processing programming right now, and you introduced a few functions I haven't seen (as well as that AMAZING affect), SO THANK YOU!! I'll comment later with my code for my sketch :)

[@ricksande2210]

You made that sketch yet?

[@נתנאל-ז2ח]

I was at the IBM Los Angeles Scientific Center where this work was done. I believe that the person shown at the terminal is Jack Cintron. By the way my name is Alfred Inselberg and will be happy to hear

[@alexmiller]

Oh wow! אביגיל בר זכור

RIP Alfred

[@MyLinuxToyBox]

Generated computer art is so interesting. What got me interested was the Deep Dream art that Google introduced. Processing and JavaScript both do some neat stuff. I also use a lot of Python.

[@PaulvanRijswijk]

Reminds me of the good old days programming assembler on the 8088 and learning about lissajous

[@PunmasterSTP]

Dang that was interesting, and I’ve been hearing a lot about Processing lately. Thanks for putting this video together!

[@lisacole2897]

Incredibly helpful thank you. I followed along and added the code as you did and it helped me understand what I was doing so much better than copying and pasting. I've managed my very first Processing programme thanks to you! Your descriptions are really clear. Now I just need to work out how to get external data to generate the maths :-)

[@fewtz9446]

it's so interesting you said "the key to that is to layer up sins and cosines on top of each other", because i knew that logically from uni- that's the basis of a fourier series

[@chbanja]

For a really nice slowmotion effect type: if (keyPressed) { if (key == 'b') { t = t-0.5; } }

[@vne8112]

+the1337er tap it if (key == 'v') { t = t-2; }

[@bastibob660]

vne that isnt slowmo its moving backwards

[@chrisgavin]

Great intro to early CG art and processing too. I'm just looking into processing and this was really useful. Thanks so much Mr. Miller. Here's one I made based on this... float t; float ball1x =0; float ball1y =0; float ball2x =0; float ball2y =0; void setup() { frameRate(25); background(20); size(720,720); } void draw() { background(0); stroke(255); strokeWeight(1); translate(width/2, height/2); rotate (radians(t)); for (int i=0;i

[@ProjectDevious]

Thus looks amazing

[@simasglebavicius2085]

Brilliant

[@tomasgomez1906]

what is "n" in that code?

[@robertmullally8001]

[@josetordesillas6706]

Awsome tutorial, thanks Alexander!!!!!

[@1houraweekmathclass]

Great tutorial! Nice pace, perfect size font and output and informative narration.

[@jamesfelix]

thanks for the video, i’m excited to learn processing

[@electron7373]

Thanks Alexander! Really interesting process. I will do some experimenting - looks like there are a lot of possibilities.

[@xtevetyler5332]

ah ha . Lissajouss images, I used to generate such images using my own Bresenham's line algorithm's and fast symmetry circle construction without sin/cosine derivatives simply mirror *8 and compute

[@MinnoqWV]

Thanks Alexander, this is a great tutorial, very helpful!

[@hellobluedays]

how to save the video man ? but when i saved it to png the outcome was blank and all black. Does anyone know how to solve this? // y = 5x // x = 5t // y = 3t + 3 static final int NUM_LINES =10; float t; void setup() { size(500, 500); background(0); } void draw() { background(0); stroke(255); strokeWeight(5); hint(DISABLE_ASYNCSAVEFRAME); saveFrame("output/gol####.tif"); translate(width/2, height/2); for (int i = 0; i < NUM_LINES; i++) { line(x1(t + i), y1(t + i), x2(t + i), y2(t + i)); } t++; } float x1(float t) { return sin(t / 10) * 100 + sin(t / 5) * 20; } float y1(float t) { return cos(t /10) * 100; } float x2(float t) { return sin(t / 10) * 200 + sin(t) * 2; } float y2(float t) { return cos(t / 20) * 200 + cos(t / 12) * 20; }

[@joeyesposito4894]

inspiring! im a designer and musician who failed math and i type with 2 fingers. code scares me, but you're opening me up! you showed me in this video that it doesn't take much to get something cool moving around. Question.. if i was to dedicate time to learning a programming language for generative art, which would you suggest? JS, Python?

[@sktkkk1]

JS, HTML, CSS

[@ishi92]

how would you make the camera follow the movement of point? For example: In the first case where you make the function x return the value of t -> the point moves right along the horizontal plane and eventually out of bounds (towards infinity) -> how would make the camera follow this movement? Cheers for the video!

[@LolindirElros]

This was such an inspirational video! I ran into Processing maybe a couple of years ago, but was kinda discouraged by the sheer amount of stuff you seamingly needed to know to be able to work with it. But this video used stuff I was familiar with, even if I don't use it since high school almost 10 years ago, and applied it in such a cool way that made me download it instantly and started messing with it. Of course there's stuff I'm lost af but at least I'll try to keep doing stuff. Thanks a lot! P.S: I love the header logo on your website!

[@EMPOWA]

thank you so much! such a great run through of parametric lines and processing.

[@PharoahJardin]

If you look closely at the original video, you can notice that no lines actually disappear or appear, they "glide" from one position to another. Whereas in your animation, its seems as though they're not moving at all : the last line disappears and a new line appears in the front, but no line actually glides...

[@saeedzare2410]

such a cool code remind me of old memory Basic with Commodore 64 Thanks !

[@mikejones-vd3fg]

Thats so cool, the visual at the end reminds me of dancer. Maybe thats why we find dancing attractive, we're sort of mimicing natures formulas of movement i imagine.

[@gregfield4457]

[@TheAlexBoro]

This blew my mind, thank you very much.

[@MarieAmeliaFreyaAster]

It's cool, could you do a more detailed video about the maths?

[@duality4y]

hmm i would have made a list of points. but that would have complicated things in a way. maybe a ArrayList since that is a linked list and you can just remove elemenst and then just remove the first if bigger then X and keep adding to the back.

[@annickwildeboer2037]

Hey everyone. I just made a tutorial on zooming/panning in Processing, and I'd love for tips and suggestions in the comments. Thanks!

[@santiagojaramillorodriguez8272]

is there a possibility to make this with another kind of movement? maybe bassed on another kind of wave?

[@rawzey]

Fantastic find!

[@toleliart1014]

Any idea how to get one of the points to follow the mouse? I can only get it to change the angle very slightly.

[@gr4hamm]

if I wanted to have it stop in place how would I do that? is there I could make the floats freeze? or would it be in the for loop? sorry I'm a noob lol

[@ifoundthistoday]

nice one

[@y_j_w_y_j]

This is a great video. However, one thing that I don't understand ---------- "float x (float t)". Is it a short form of a function? like " i++" is a short form of "i = i+1"?

[@alexmiller]

No, it's not a special short form, even though it looks odd. It's a function called "x" that returns a float, and takes one float parameter "t". An equivalent function header would be: float myFunction(float myParameter)

[@y_j_w_y_j]

Thanks for answering

[@benkada8847]

Great video, also very inspiring

[@Miionu]

Great video! I want more of these! 😁

[@binershock]

This is cool and thanks for making it- one question is about frame rate. It seems like according to documentation the default frame rate is going to be 60 frames per second, but in your example things seem to move slower than that. I don't see you alter the frame rate explicitly.

[@sparkloweb]

It's rendering at 60 fps. You can tell when it increments one pixel at a time across half the window (250px) in just over 4 seconds. But the video appears to be captured at only 24 fps.

[@TheJunolao]

I just love you man, keep it up :3

[@that_billu_guy]

so cool float t; void setup(){ background(30); size(2500,2000); } void draw(){ stroke(255); strokeWeight(5); translate(0,height/2); point(x(t),y(t)); t++; } float x(float t) { return t; } float y(float t) { return tan(t*101) * 100; }

[@animanoir]

is there a way to create the grainy vibrating effect too?

Great! Lovely stuff mate.

[@Nathan666ismynumber]

Hi Alexander do you have any of the codes saved so i could take a peak please?

[@nikolchang4571]

i just do exactly same type as you are,but i'm stuck in 'point(x(t),y(t);)',my computer alert me 'function y(float) doesn't exist' how can i fix it?

[@bjornsundin5820]

NiKol Chang well.. you need to make the function. also, put the ; at the very end of the line.

[@moritzheinzel815]

I found this: float t; float mx = 250; void setup(){ background(20); size(500, 500); } void draw(){ stroke(255); strokeWeight(1); line(0, 250, 500, 250); line(mx, 0, mx, 500); translate(mx, height/2); line(x(t-1), y(t-1), x(t), y(t)); line(y(t-1), x(t-1), y(t), x(t)); t = t+50; } float x(float t){ return 100*sin(t) + 200*cos(-t); } float y(float t){ return 100*sin(0.5*t) + sin(t/30); } Trust me its amazing.

I exactly copied the code but Processing (3.4) doesn't let me play it, saying that float t; is an unexpected token. Same for void setup();. What's wrong in my code? // y = 5x // x = 5t // y = 3t + 3 static final int NUM_LINES = 10 float t; void setup() { background(20); size(500, 500); } void draw() { background(20); stroke(255); strokeWeight(5); translate(width/2, height/2); for (int i = 0; i < NUM_LINES, i++) { line(x1(t + i), y1(t + i), x2(t + 1), y2(t + 1)); } t +=0.5 } float x1(float t) { return sin(t / 10) * 100; } float y1(float t) { return cos(t / 10) * 100; } float x2(float t) { return sin(t / 10) * 200 + sin(t) * 2; } float y2(float t) { return cos(t / 10) * 100 + cos(t/12) * 20; }

[@jarnoburggraf8846]

Did you forget the semicolon after numLines=10?

[@justgame5508]

Because you call t += 1 before you’ve initialised t. Instead of: float t; Write float t = 0;

I have something I made in QB45 when I was 13ish. Seems I independently discovered this. I learnt/discovered how to draw a circle pixel by pixel. I was also bouncing lines off the edges of the screen. One day I made a very small program that did what you just did. I had no idea how it worked. All I know is nothing in the code was telling my line ends to bounce off the edge of the screen, yet it was doing it in a non repetitious way. I was also able to use all 256K colours, but only 16 at a time. Then I lose the fucking source code, All I have left is an EXE file :(
