We closed this forum 18 June 2010. It has served us well since 2005 as the ALPHA forum did before it from 2002 to 2005. New discussions are ongoing at the new URL http://forum.processing.org. You'll need to sign up and get a new user account. We're sorry about that inconvenience, but we think it's better in the long run. The content on this forum will remain online.

Context Free Design Grammar
May 17th, 2005, 11:39pm  
Chris Coyne has defined a simple syntax for describing shapes that he calles Context Free Design Grammar (CFDG). CFDG is simple but powerful, and works much like L-systems and other string-rewriting rule systems. It's certainly no competition for Processing, but it allows you to think about recursive structures in a nice way.

My favorite image is this one: Funky Flower

- Gallery of CFDG images
- Download CFDG for Win/Mac/Unix
- Run CFDG online in a PHP-based renderer

it could do with a postscript output. it'd be nice to be able to bring patterns into illustrator for print.

Good point. Their source code is available here: http://www.ozonehouse.com/ContextFree/download.html. Unfortunately (or not, depending on your preference) it's in C++.
