Once the L-system has been run for the specified number of generations, the resulting string will be interpreted (see below). How to pass rules into the L-system: The 'rules' list is a list of tuples, each tuple being a rule for string substitution. Each rule tuple has two parts, a single character to look for, and a string to replace the character with. Here's an example: ('0', 'EM0') This rule means that every time '0' is encountered, it is replaced with the string 'EM0'. If our initial string is '0', and we apply this rule for, say, 5 generations, we end up with the following progression: 0 -> EM0 -> EMEM0 -> EMEMEM0 -> EMEMEMEM0 -> EMEMEMEMEM0 How the result strings are interpreted: A complete description of the symbols can be found in the doc string for this module, but here is a brief summary: S scale the face M move the face along the face's normal E[...] extrude the face and branch the L-system (definitely see the doc string for more info) T ignored 0-9 ignored (used to represent faces at the string-substitution stage, useless once string-substitution is complete) is%At least one polygon must be selectedNi( sget_selected_polysspolysslensLSystemsaxiomsrulesssystemsdones generations generationssstepsinterpret_actionsstring(saxiomsruless generationsspolysssystem((s./lsysinterp.pys run_lsystem‚s  N( s pykludge3dslsystems scale_faces move_faces extrude_facesget_bracketed_substringsinterpret_branchessinterpret_actions run_lsystem(s scale_faces extrude_facesinterpret_branchess run_lsystemsget_bracketed_substringsinterpret_actions move_face((s./lsysinterp.pys?s  !
