3d lindenmayers in jitter

    dear list,
    i tweaked a jitter patch which generates two-dimensional fractal images based on lindenmayer strings (L systems) using jit.linden. the 2D images generated by this process are currently visualized in jit.lcd. my next step is to convert (or better to map) the jit.linden matrix output to a jit.GL object and generate a 3D version of the lindenmayer fractal - and here's where i'm stuck. i tried different combinations, but couldn't find a properly working way to get the fractal going from 2D to 3D. i guess jit.linden outputs 2-dimensional data, but there should be a way to convert the simple 2-dimension movements to 3D data (for instance, convert direction and position to rotation and angle).
    any ideas?
    will appreciate anyone's help, thank you!
    Spk.

      hello,
      can't help you more at this moment than offering these links to this beautiful book on the subject by Dr. P. Prusinkiewicz - The Algorithmic Beauty of Plants:

      you'll find more info on the subject at above site, highly recommended.
      best, nesa

      a great book indeed, and i remember seeing 3d-l-systems in there too, which might point you in the right direction. There is nothing implicitly 2d in l-systems, it all depends on how your 'turtle' interprets the strings generated.
      ciao,
      Joost.
