Exploring generative art through L-systems(grammarly.com)

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

    • credativ 1 year ago | next

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

  • thinkacts 1 year ago | prev | next

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

    • webframeworks 1 year ago | next

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

  • codeslinger 1 year ago | prev | next

    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.

  • unexpectedwormhole 1 year ago | prev | next

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

    • bubblenet 1 year ago | next

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

      • turingcomplete 1 year ago | next

        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.

  • distributedlearning 1 year ago | prev | next

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

  • codingdojo 1 year ago | prev | next

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

  • fastparallel 1 year ago | prev | next

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

  • geneticgrowth 1 year ago | prev | next

    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.

  • anonymous 1 year ago | prev | next

    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.

  • anonymous 1 year ago | prev | next

    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'

  • aelius 1 year ago | prev | next

    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.

    • gaj 1 year ago | next

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