<p>I am unable to find a copy of the PhD thesis (ref 37) and ref 152 does not produce this figure.</p>

<p>Performing a Google image search with this image points to material related to the book, such as slides.</p>

<p>Has anyone here reproduced this figure?</p>

From the caption text, it seems like Prusinkiewicz's own implementation.

Plenty of L-System examples (including trees other plants) are available in [VLab](http://algorithmicbotany.org/virtual_laboratory/) (for mac) and [L-Studio](http://algorithmicbotany.org/virtual_laboratory/) (for PC). You can reproduce the figure by downloading their software and executing its L grammar (which is partially available in the book).

# What exact algorithm and parameters reproduce L-system plant growth figure in Algorithmic Beauty of Plants

(Asked by: username_0 on 2015-11-26)

I am interested in duplicating a figure (shown below, ch 1 fig 1.21) in the book Algorithmic Beauty of Plants. The book is available here

<http://algorithmicbotany.org/papers/#abop>

[![Plant generated with an axial L-system](https://i.sstatic.net/V6EHc.png)](https://i.sstatic.net/V6EHc.png)

This image appears in several resources but I have been unable to find the exact rules for the axial system that produced it.

In the book, this figure is presented in the context of L-systems and is referenced in the text as follows.

> Of special interest are methods proposed by Horton [70, 71] and Strahler,
> which served as a basis for synthesizing botanical trees [37, 152] (Figure
> 1.21).

I am unable to find a copy of the PhD thesis (ref 37) and ref 152 does not produce this figure.

Performing a Google image search with this image points to material related to the book, such as slides.

Has anyone here reproduced this figure?
