8.5: L-Systems - The Nature of Code

[@egregory314]

Wonderful! I've literally spent the last 3 hours creating images from the ABOP book. Made some additions to the turtle capabilities. Thank you for taking the time to create these classes!

[@neodos]

Thank you for making and sharing these lessons, it's a pleasure to learn when it's so well and simply explained and with passion, great stuff, thank you!

[@Pastelgarbage]

I wanted to learn l-system but I think there are many things I need to learn first, funny how it makes so much sense and is also so confusing at bits. we will get there

[@WilliamLDeRieuxIV]

The way this guy explains L-Systems is very clear. We have a clear explanation of the algorithm and its conceptual design--how to define the expected inputs and outputs--and how to translate the design into code (he explained it using very clear and natural language--without "getting-down-in-the-weeds" on the pedantic nature of algorithms like fractals/Cantor-set). I know we have all had teachers, at some point, that have explained concepts like this in a pedantic way (eg. getting lost in overly small details--going off on a tangent--and diverging away from overall concept) But at: 15:05 he says we have a string named: "todo dot length"....hahaha...

[@ludacrisbutler]

my (Python) textbook explained an axiom in like 3 sentences- not nearly in-depth enough. thank you for this.

[@zeldaquest4206]

3 sentences means... go somewhere else... lol

[@unicorn_loves_potato]

Thank you for posting such easy-to-understand, intuitive and fun tutorials! I have been looking for them everywhere, and this really works out the best for me. I successfully made different L-system plants with the string parsing as you taught. The video is really great!

[@TheCodingTrain]

+monetti thank you! feel free to share your work!

[@mikeCavalle]

great exposition -- i wrote a LOGO in Pascal in the 1980's

[@li-lianang8304]

Great lesson! i love your enthusiasm hehe

[@davidpike766]

Got here from reading about No Man's Sky. Great videos, great teacher. Thanks.

[@TheCodingTrain]

Glad to hear, thank you!

[@adriancardenosocerezo]

I understand that these l-system patterns are achieved by first drawing something at the fractal level and then implementing it with this system, right? There may be some random result that one might be interested in, but in principle one tries to generate an aptron that one knows will work, right? In other words, these patterns that you have shown are not trial and error, it is the encoding of that type of tree. Thanks for the videos they are great!

[@trudyandgeorge]

Wonderful mate. Your enthusiasm and energy is wonderful. Please set your video editor to canvas+ output the same frame rate as your video capture devices, i.e., your camera and screen-cap software to be the same as the resulting video in Premier or Final Cut, or whatever. It should get rid of some bad artifacts going on with the frames. Thanks for the vid!

[@TheCodingTrain]

+George Edwards Thanks for the feedback, this video is from a few years ago and if you look at more recent ones on my channel you'll see how the quality has now been improved!

[@KoalaTeaGuy]

Great video! Was a huge help for my java class

[@LordGrrr]

Thumb up at the start, like the others :D

[@SunnyApples]

From No Man's Sky wiki to your video!

[@TheCodingTrain]

welcome!

[@nagesh007]

Amazing Tutorial

[@TyYann]

I still use Logo programming language...

[@carterfrerichs5814]

thank you so much! your channel is amazing!

[@veronicacasco1958]

great exposition -- Is it possible to model an agave plant using fractal geometry? the agave plant is a fractal?

[@az_arq2306]

Hola, ¿Dónde descargo el software l-systen?.

[@darkvaporwave]

Mindblown!!!!!

[@Ha-ppi-ness]

Love your channel. Loved your book. Sending love.

[@TheCodingTrain]

Thank you!

[@shushufang9079]

I love his positivity just like DB"s @Porter's

[@nagesh007]

Thanks!

[@TheCodingTrain]

Thank you for the support!

[@Kirayli]

Nice Video! Thank you : )

[@unos8049]

Inspiring video!

[@MartinStacey]

can this be used for shape grammars?

[@putrinaryaa5861]

I'm sorry, + is left and - is right 🙏

[@tube88aman]

Hello, you explained it very nicely. what language you used in this example, I only know c++ :( Can I have the codes please ?

[@TheCodingTrain]

+tube88aman It's Processing (processing.org) which is built on top of Java. Code here github.com/shiffman/The-Nature-of-Code-Examples/tree/master/chp08_fractals/NOC_8_08_SimpleLSystem github.com/shiffman/The-Nature-of-Code-Examples/tree/master/chp08_fractals/NOC_8_09_LSystem

[@tube88aman]

+Daniel Shiffman Thank you very much :)

[@mistyriver2695]

Well explained.

[@TheCodingTrain]

+Misty River thanks!

[@rizwanafzal3809]

Can u provide complete code ? including code that you used to draw tree in this video ?

[@Crowborn]

There's a link in the description for the github ;)

[@tonyrogers7101]

fungi !== plants

[@Simmonsstummer]

awesome

[@sharketespark6495]

Am I tripping or is it just the video

[@ExpertPower]

Yeah :)

[@veerrajuyeleti8541]

sir add some videos on recurssion

[@ramseshendriks2445]

I just ordereres your book

[@TheCodingTrain]

Thanks for the support!

[@matthewe3813]

who are the 8 people who disliked this?

[@NStripleseven]

Wonder what would happen if instead of making instructions for drawing, you made instructions for a sort of simple programming language, something like brainf***

[@duncancarr7822]

These are all really just ridiculously long Rubik Snakes
