Then you pick a back-end renderer and hit Render. See http://wiki.rubygarden.org/Ruby/page/show/FractalLifeEngine/LampTutorial for the complete cycle

While working on Flea, I explained to my woman I was spending all my spare time "writing a program that generates complex photorealistic shapes, like trees, using short primitive rule sets". Not in so few words.

She said, "Can't you just download pictures of trees from the Internet?"

I hope you told her no. Trees you can find, but when you want a particular type and placement, it can get very difficult. Even if all I cared about was having something that looked tree-like, and not the underlying principles, I'd be much happier if I could grow my own.
