8.2: Fractal Recursion - The Nature of Code

This video looks at how to write functions in Processing that call themselves (recursion) for the purpose of drawing fractals.

My favorite thing about your videos is you teach things that are interesting to you, and by extension they have fascinated me. Great work and I love your book.

[@developercorey1082]

This rabbit hole leads to some very in-depth knowledge and understanding. It's always nice to see how you portray your information. Keep up the awesome work. I look forward to seeing your future uploads.

[@dukkhan1288]

"You can stop the video now because you've probably done enough." Yeah right, because anyone who's made it that far isn't absolutely fascinated with your lessons.

[@jasonedward]

With this video you have just unlocked the key to infinity. Thank you for sharing this

[@DiamanteKlopman]

This videos are great, I wish they soon get the amount of views something this good deserve.

[@collectionchannel1624]

I need to learn more about this circles and the numbers they hide and the secret behind them because they are important in trading

Hey! Do you think you could do a series on D3? I really like the way you teach and can't really find any good youtubers for D3. Thanks!

[@TheCodingTrain]

I will consider it, yes. But it will probably be a while before I have time to get to a new JS framework.

[@markoichise-briscech4654]

Many thanks for the vids Dan, I appreciate them a lot :D

[@veerrajuyeleti8541]

sir can you do videos on dynamic programming in real life applications please

[@amitthakkar22288]

this is wrong, you make coding sound like fun. :D .

[@hammer158]

Seriously!!DONT!!!!!

[@sujandutta8981]

you should have searched Devils' curve instead! :p

[@MPAYNE-ij1jh]

Hi, is there a way to create a fractal zoom from text? I'm hoping to do this for my Uni project! I hope this made sense

[@realcygnus]

loving this channel !......so neither the processing or the p5 IDEs have any form of an intellisense(I think thats what M$ calls theirs) ? to auto-list available items etc...or a type prediction or way to find other references of highlighted area etc.....I could swear i seen it active in one of you vids.......was it a different IDE....what was it ......& was it for pde or p5 or both ?.... does anyone know?

[@latifguliyev]

Thanks for great tutorial, are there any IDE for Fractals or any apps that can use?

[@TheCodingTrain]

+Latif Guliyev These tutorials and the example code are designed for use with processing.org, check it out!

Amazing

[@randmorf]

Has anyone tried this with Python Turtle Graphics? It seems like the circle() method is different than in Processing. In Processing, it seems each circle is drawn relative to the center of the circle, while with Python Turtle Graphics, each circle is drawn relative to the turtle which is on the circumference of the circle. I was able to correct for this with a recursive program that can draw a series of concentric circles, but when I put in off-sets so each recursive circle is drawn further out along the x-a is, my correction code pulls it back so it’s drawn relative to coordinates 0,0 in the middle of the screen. I suppose it would be easier if I switch to Processing, but everything else I do these days is with Python.

[@randmorf]

I figure it out in Python Turtle Graphics... # Python Turtle Graphics - Recursive Circles v3 ==> "Sierpinski Triangle" # # Inspiration: "The Nature of Code" by Daniel Shiffman # Chapter 8.2 - Recursion # # URL: natureofcode.com/book/chapter-8-fractals/ # import turtle def drawCircle(x, y, radius, correction): # Re-center the circle... t.penup() t.setposition(x,y-radius) t.pendown() # Draw circle.. t.circle(radius) # Call self again (recursion) if radius > 2: #t.color("red") drawCircle(x + radius, y, radius/2, increment) #t.color("green") drawCircle(x - radius, y, radius/2, increment) #t.color("blue") drawCircle(x, y - radius, radius/2, increment) #t.color("magenta") #drawCircle(x, y + radius, radius/2, increment) # Main Code: scn = turtle.Screen() # Request a screen object, call it 'scn' scn.bgcolor("skyblue") # Set screen background color scn.title("Recursive Circles 3") t = turtle.Turtle() # Create the turtle object, call it "t". t.speed(0) t.hideturtle() t.pensize(1) radius = 150 increment = 25 t.color("black") drawCircle(0,0,radius,increment) print("Done.") turtle.done() # EOF

Have you ever used grasshopper?

[@fruityang9681]

You're amazing :')

[@andrawina6571]

How to create video like this?

[@franksimon8375]

I'm doing a 5d to 3d nature model thing

[@1oglop1]

how could you learn all this?

[@TheCodingTrain]

+oglop For additional references check out natureofcode.com. Hope this helps!

[@1oglop1]

+Daniel Shiffman I meant that my brain is not capable to remember it all. Maybe I'll try to record some videos to, to help me remember but, thanks I will try

[@TheCodingTrain]

+oglop oh I see!

[@CuongNguyen250690]

Understand. Do not remember. As you see even Daniel Shiffman usually forget the mini step, but eventually he gets back on track because of deduction.

[@AryehAmitz]

Ever use Incendia EX?

[@TheCodingTrain]

+Indigo Veilplume i have not, but will check it out.

[@18ipmg]

Lol going deep with this vid.

[@DlcEnergy]

12:09 The matrix is lagging again...

[@franksimon8375]

Code plz p5. I'M LAZY!!!!

[@TheLiquidAtom]

holy shit illuminati

[@crimsomnia1415]

Now program a recursive genome of a living creature (or a virus) xD

[@ronaldcabrera675]

What programming language is this? I'm just getting an error when I type in DevTools...

[@randmorf]

A language called “Processing”

[@Colonies_Dev]

looks more like C bruh

[@Colonies_Dev]

im not even sure if this is C or java ;-;

Please sub this video to english

[@MemeCult]

This person isa nerDDDDDDDD
