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


Plant generated with an axial L-system

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?

  • $\begingroup$ From the caption text, it seems like Prusinkiewicz's own implementation. $\endgroup$

  • $\begingroup$ Plenty of L-System examples (including trees other plants) are available in VLab (for mac) and L-Studio (for PC). You can reproduce the figure by downloading their software and executing its L grammar (which is partially available in the book). $\endgroup$
