The Mandelbrot Fractal Explained!

[@fuglsnef]

This is the best explanation of both the Mandelbrot set and complex numbers I've ever seen, great work!

[@TheArtofCodeIsCool]

aww thanks. I appreciate your appreciation :)

[@joshuad31]

@@TheArtofCodeIsCool this really was an exceptional video

[@ShoshiPlatypus]

Excellent explanation. Love the dance floor analogy, beautifully presented! I have struggled with maths all my life but very keen to understand the inner workings of this incredible artefact. I've just plotted the times tables visually and loving the results, and learning about the connections with the Mandelbrot Set and also the Fibonacci series which has fascinated me for years. So much to learn and my intellectual abilities are struggling a lot with it all - I feel that there is something just outside my grasp but I strive to find it!!

[@Kizzudoramu]

This is the absolute best explanation of fractal generation I've ever seen. The dancer metaphor was perfect. Great video, thank you.

[@realcygnus]

top notch channel.......best visual explanation I've seen

[@LaukkuBah]

I think the real lesson here is programming before hoes

[@TheArtofCodeIsCool]

LOL

[@codebro1785]

Clever metaphor, beautifully explained. Thank you.

[@sacredbanana]

I never thought I'd finally understand the Mandelbrot set today, but I did. You sir deserve a big Easter egg!

[@TheArtofCodeIsCool]

Cool! I'm glad it helped you :)

[@gennaroschiano8085]

You’re the man. It took me 4 years of hard work to start understanding your basic videos. One Love!

[@martingachagua4554]

Whizz Stuff. You Refreshed My Coding. The Dance Floor illustration And How The Steps Could iterate Was Superb. Then You Showed How Your Computer Operated On The Variables To Create The Mandelbrot Fractal. Your Labor Was Worth It! After A Few Videos . . . . This Was The 4th, . . . . . I Feel That You Took It Home For Me. Appreciated.

[@TheArtofCodeIsCool]

I'm glad you got something out of it!

[@nameno7032]

Best dance competion i ever watch Please make more of, this kind of analogy is so much fun and easy to understand the concept behind.

[@THE_ONLY_GOD]

Bravo! That transition from maths to code was great and filled in what had been missing about that. Thanks! Truly appreciated!

[@godramen7104]

Absolutely brilliant explanation of the Mandelbrot Set. I always come back to this video to learn more about it. This is beautifully done.

[@MariusPartenie]

Hello! Great video. While I watched some videos about the Mandelbrot set that delve into the mathematics (on the Numberphile channel), your analogy with the dance competition really connected everything together. Thanks!

[@cebustama]

I saw the dance hall setup you created and instantly subscribed. Amazing video and content!

[@video_games23]

Only 5k subscribers? Super underrated.

[@davidgb3652]

you don't know it, but I'm watching all your videos as if you were my teacher. I owe you a lot.

[@sanchit8818]

Just found this video today. I have always wondered about this but never found an explanation this good. Thanks!

[@murators4732]

WOW! You explained it so well! Just subscribed. Because I watched several videos and so I just better understand how well you explained it! Couldn’t be simpler. Will watch your other videos! Just could be as good as this one! Thanks!!!

[@gabriel-mk7jk]

Amazing, studying this in computer graphics for over a year and neither my tutors or anyone on the internet has been able to explain the number's behavior so simply. Really clicked after watching this, bless x

[@TheArtofCodeIsCool]

Wow, great! I'm glad it clicked :)

[@davidhopkins]

Thanks for this. The dancer analogy was really helpful. I am most appreciative that you did the hard work of explaining how you square and add complex numbers. The numberphile videos pretend to explain things but they breeze right over how this works.

[@TheArtofCodeIsCool]

Glad it was helpful!

[@davidbigras1012]

Wow!!! Never thought I could have such a deep understanding of that set!!! You did a fantastic job!!!

[@hitman17011986]

Woww.. Never knew someone could explain it so well.. its just amazing! Thanks a ton.

[@alextrollip7707]

This was mindblowing. The comparison, example and presentation was top notch. Amazing.

[@ClarkPotter]

This (fractals), holography, dissipative structures (and autopoiesis), and cellular automata are most of the ingredients you need to create an evolving universe replete with consciousness. Fantastic video. Subscribed.

[@oneofthesixbillion]

Thanks, I especially appreciated 2 things. I've been confused by complex numbers and you showed how to work with them using simple algebra. Also the dancer analogy that showed how the start point affects whether the given number goes out of bounds gave me a nice conceptual understanding. I was completely confused about how the points map to colors. I didn't see any point plots or how colors are assigned to the points.

[@TheArtofCodeIsCool]

The color mapping is usually based on the number of iterations. This can be completely arbitrary. If you divide your number of iteration by the maximum number of iterations allowed, you'll get a number between 0 and 1 You can then use that number to look up a color out of a texture. The texture could hold any color gradient you want.

[@scatoutdebutter]

Great job. Great explanation. This is about the fifth video I’ve watched on this and it really helps. Thanks.

[@__hannibaal__]

In the past 20 years i try very hard to visualize a fractals by reading what’s image coding bitmap, windows API, C, C++ , and at the end I FAIL , so i abandoned totally the project but i keep studying Fractal analytically, by hand and realize very awesome results. Now when i return to programming i realize how these thing is easy.

6:55 is fantastic using the initial points and seeing their progressions in animation tells a LOT about fractals ... can you make more of those?

[@ahmedsalman17]

Excellent video Thank you very much

[@THE_ONLY_GOD]

Can confirm if this understanding of difference between Mandelbrot and Julia shader calculations is correct?: Main difference is seemingly that a Mandelbrot set has a C val that changes every pixel as it basically seems to do a “for loop” style scan across each row of texture coordinates row by row in the entire frame. So at each point it is calculating the pixel color for, it inputs that texture coordinate under that pixel as C. In a julia set Z is initially set to the texture coordinate it’s rendering the pixel color for, but C is a constant coordinate val that is shared by every pixel (texture coordinate under the pixel) calculation and that val is from a specified n+i plane coordinate selected. (so in an interactive shader, the coordinate under the touch is C and then Z is every pixel coordinate in a similar “for loop” style row by row scan as the Mandelbrot). That is seemingly how that functions.

[@kjwong4730]

Very good explanation

[@radrook7584]

These fractal patterns are evident in nature and are not just computer-generated possibilities.

[@greggsannes493]

I'm still learning but you give me hope thank you😊

[@clearwavepro100]

Ingenious demonstration! :)

[@NBsTube]

you are a fucking genius, this explanation of the mandelbrot set is so didactic and useful, I would love if you can at some point do a similar explanation but about the mandelbulb, of some 3D fractal, I wrapped my mind around how mandelbrot works (and I still try to understand how the julia set works, I've seen a couple of good videos about how mandelbrot, julia set, and fibonacci correlates to the other in the channel 3blue1brown) but the moment you go three dimensional my mind explodes, my dream of all times is to really understand how to generate 3D fractals with raymarching, but not as many other videos do where they just show the code, but UNDERSTANDING it, thats the part that excites me. Keep doing these amazing videos, I found you last week and I love your shader tutorials, they are both good for newbies and for intermediate shader devs and computer scientist in general, I thought I would never find a shader veteran that also loves to didactically explain his knowledge.

[@TheArtofCodeIsCool]

Wow... thanks for your nice words! The 3d fractals are on the agenda. You raise an interesting point about not just blindly copying something, but actually understanding it. Videos ideas often have to bounce through my head for a few months before I know them well enough to be able to explain them well, and not just code them.

[@NBsTube]

@@TheArtofCodeIsCool yeah definitely, I like how you introduce stuff, concept by concept, you don't go for the big fish first, you introduce concepts and knowledge in layers, each one more complex and built around the previous one, that's the best way to learn, otherwise the overdose of new information usually frustrates people.

Better explanation than professors at the university

[@davidhopkins]

This is hands down the best explainer of the Mandelbrot set. Is the dance program you use available for the public? My nephew is obsessed with this stuff and I have been struggling to explain it to him. I think it would really help if he could plop down his own dancers on squares of his choosing and watch them go.

[@TheArtofCodeIsCool]

It's not available at the moment but you're not the first one to ask so I'll polish it up a bit and release it to the public.

amazing, it's the best one in youtube

[@prietjepruck]

Very clear explanation. Dank je wel. :-)

[@hareecionelson5875]

it just occurred to me that, if multiplying by i is a rotation of 90 degrees (anti-clockwise), then multiplying by -1 is a rotation by 180 degrees imagine if negative numbers were explained at school in the context of rotation: it would make the jump to imaginary(terrible name) numbers a lot more intuitive, since i x i =-1, which is a total of two 90 degree rotations

Much appreciation i was wondering i we can we get the source code

[@kebman]

The steps explains why the computation of the Mandelbrot set becomes slower and slower as you zoom in. Isn't there a way to compartmentalize the zoomed area, so it requires less computation? Edit: isn't it just a matter of making the test area smaller?

[@TheArtofCodeIsCool]

That's a great observation. Yes, when you zoom in on an edge of the fractal what happens is that all of your dancers dance more steps before leaving the dance floor which makes the competition last longer and the frame longer to render. There is not really a way around that.

[@THE_ONLY_GOD]

How to put a rotating raymarching object into every "orbit trap" of that fractal in Shadertoy?

[@sawdustwoodchips]

Hi there, just stumbled across your video - the explanation was great!! - I have tried using your code in shadertoy, but I am getting lots of errors. do you have a listing of the code - I get lots of undefined. will understand if you do not want to share. all teh best!the

[@yendorelrae5476]

"so that's...kinda how...this algorithm works" I think he is trying to explain it to himself at times

[@frankconley7630]

Using the dancer example, when you zoom in 10 or 100 times what are you looking at. I'm flummoxed. I cant learn what the shapes are when i watch Mandelbrot zoom videos. What determines the shapes and colors around the focal point? Please respond. Anyone.

[@TheArtofCodeIsCool]

You are looking at the scores of the dancers that started at the exact locations you zoomed into. The colors are just the score, mapped to a color. You are free to turn scores into colors anyway you like. Here, I use the score to look up a color from a texture with color gradients.

[@JenabeSaber]

Very good job

[@lordawesometony2764]

The Collatz conjecture. How can the rule change itself? When applied normally Odd: 3n+1 Even: n/2 When n reaches the number 1, it also changes its own rule for odd. It no longer is: 3n+1 It is: 3n+n and that is why it falls into a repeating problem. 1,4,2,1,4,2,1... But when you replace the “n” with any odd number in the equation: 3n+n it makes the same repeating pattern: a,b,c,d,a,b,c,d,a

[@lordawesometony2764]

Are there other equations that can change into another equation?
