a little bit of l-system confusion.

[Ezz]

Hi good Houdini-folks.

I have a little puzzle about l-system and edge-rewriting.

I had this understanding, that the l-system rules where executed all at once in each generation.

However with this simple l-system the full rewriting accurs after every secon generation.

premise: A

rule 1: A = FB

rule 2: B = &FA

0. generation the l-system gives only the premise wich is logical

if the rewriting accures at once, the 1. generation of the l-system should return F&FA

but it returns: only FB and so on

Its like it skips every second generation in the rewriting process.

Does anyone have an explenation to this??

Thanks a bunch

"I had this understanding, that the l-system rules where executed all at once"

that is right,

but what you expect is that they are executed one after another...

so in first generation rule2 has nothing to do becaouse there is no B,

and in second generation rule1 has nothing to do because there is no A,

write those rules in single rule or write them so that you have A and B in every generation...

Hey.

Thanks a lot for your response and making it clearer for me.

It all give more sence if I did the rewriting on a piece of paper.
