This app will generate a random tree-like collection of lines at user-picked points.

A number of parameters can be adjusted by the user to fine-tune the look and feels of the generated trees, such as trunk length, number of iterations used, branching probability, max zenith angle for the branches, branch ratio and minimum branch length.

Since version 2019.4.11.1 tree generation is dynamic/interactive allowing you to preview the end result in real time

Interactive keys:

N key: Generate new tree

Up/Down arrow keys: increase/decrease the trunk length by 20%

Right/Left arrow keys: increase/decrease the max zenith angle by 10%

PgUp/PgDown keys: increase/decrease the number of iterations by 1

Plus/Minus keys: increase/decrease the branching probability by 1

Home/End keys: increase/decrease min branch length by 10%
