Great article on L-systems! I've been fascinated by the concept ever since I heard about it.

Same here! Exploring the connection between L-systems and plant morphology is on my to-do list. Thanks for the inspiration!

Question about the implementation: what's the most efficient way of rendering L-system outputs in a browser?

HTML5 Canvas is a good choice for rendering large numbers of simple shapes due to its good performance.

Does anyone know of any research on L-systems and computer animation?
cld 1 year ago next
@codeslinger Yes, look up the classic work 'Cellular Automata and L-Systems - A New Approach To Computer Animation' by Grzegorz Gawin from 1988.

I'm currently working on a project involving L-systems and physical simulations (wind, gravity, etc). Any pointers?

Try looking into dynamic reconfigurable body frameworks for realistic simulations. There are also great libraries like RAPID-MIX for physically based simulation.

Also, don't forget the 'Physics for Game Programmers' series on brakefall.org/books. It covers the basics of physics simulations for programmers in a concise manner.

@unexpectedwormhole Good luck with your project! Would be awesome to see the results.

Damn, that's some interesting art generation. Might try my hand on a tutorial on that topic for our next dojo. Thanks!

Related: I recently came across the idea of shape grammars, which is an interesting generalization of L-systems in the context of 3D art.

Question: How is L-systems different from genetic algorithms?
neuralloop 1 year ago next
Great question! With L-systems, you explicitly define rules for string transformation. Genetic algorithms are population based on producing potentially better solutions via mutation and crossover.

This is insanely cool! Any chance we can contribute to the code within some sort of open-source framework? I'd love to play around with it further.

There's a new Hacker News story submission for related R&D on Nathan Friend's (@neuralloop) website about L-systems: 'L-Systems and Physical Simulation experimental studies'

Many years ago, I crafted a lengthy tutorial that illustrated how to create a fractal tree generator using L-systems and was wondering how it could be evolved in the context of current JS ecosystem.

You could use Canvas integrated with FabricJS to handle graphical aspects and coordinate transformations. Also, ThreeJS might be worth considering for 3D rendering utilities
