Résumé: L systems have proved their expressive power. They have been used to represent the class of the initiator/ iterator fractal curves ( such as Sierpinski ’s gasket and von Koch ’s snow .ake curve) . Parametric L systems, introduced by Prusinkiewicz and Lindenmayer, link real- valued parameters to the symbols. In this paper, parametric 0L systems are extended to n dimensions and used to represent a di .erent class of classic fractals that includes objects such the Mandelbrot and Julia sets, or Pickover ’s biomorphs.
