The TurtleInterpreter could be used by itself or together with the LSystem component giving you the opportunity to explore new designs. RABBIT 0.2 provides a 3d Turtle Interpreter: the “turtle” moves and draws graphics in 3d. The cumulative product of commands creates the drawing. Each command modifies the turtle’s current position, orientation and pen position on the drawing surface. The historical term turtle interpretation comes from the early days of computer graphics, where a mechanical robot turtle (either real or simulated), capable of simple movement and carrying a pen, would respond to instructions such as ‘move forward’, ‘turn left’, ‘pen up’ and ‘pen down’. The derivation strings of developing L-systems can be interpreted as a linear sequence of instructions (with real-valued parameters in the case of parametric L-systems) to a ‘turtle’, which interprets the instructions as movement and geometry building actions.

Designing with L-Systems Series by Griswold, Ralph E.The Algorithmic Beauty of Plants & other papers.Following the picture, fill in the line for the mouth and the little circle for. There exist different types of LSystems: deterministic, stochastic, context-free, context-sensitive, parametric, timed-depending on the rules and the way they are applied by the LSystem.įor more info about LSytems, we strongly suggest the following resources: For the ears, draw two leaf shapes on top of the head. Since their original formulation, L-systems have been adapted to modelling a wide range of phenomena including: N is the derivation length = the number of iterationsĪll these words form the language of the LSystem. The LSystem starts with the seed ‘A’ and iteratively rewrites that string using the production rules. A string rewriting system consists of an initial string, called the seed, and a set of rules for specifying how the symbols in a string are rewritten as (replaced by) strings. In Brief: LSystem is a parallel string rewriting system.
With RABBIT 0.2 by MORPHOCODE you would be able to create different types of LSystems: (deterministic, stochastic, context-free, parametric) and visualize them as geometry structures.
The upcoming release contains new powerful tools: LSystem component and a 3D Turtle Interpreter component. MORPHOCODE is working on the new release of RABBIT – our plug-in for Rhino & Grasshopper. Music: “The Slackers” Exploring LSystems in 3D
