问题
I am about to start a project for university to build a procedural city for a pre existing project.
I was wondering if any of you have had any experience coding L-Systems before and know a good place for me to start out. I have done a bit of work before using procedural methods and Perlin Noise and fBm so I get the premise of what an L-System is in the fractal sense. I am more looking for a place where maybe can push me in the direction of coding the L-System. Any help or technical documents you can point me towards would be great.
回答1:
I did a project on using L-Systems to procedurally generate 3D trees and found the book "The Algorithmic Beauty of Plants" helpful. It's available for free at that link. Not directly related to procedural cities, but very interesting, and a good resource to learn about L-Systems, I think.

I'm working on an L-system project too, and it's been tremendously helpful to look at some pre-existing code: lsystem.py - There's also pseudocode in Fundamentals of Natural Computing which I found really helpful. It takes you through the process of using turtle graphics to create a simple L-system tree, and quickly moves on to more advanced stuff.

Well ... I'll go first and hand you the Wikipedia link, which looks reasonably meaty, and has quite a few external links of its own.
