..not novelI haven't written anything on here for a while, this is the first opportunity since quite some time. It won't be in-depth. The following post assumes you've experimented with LSystems before.
Scripted Node MKI can read rules, (text files, one called RULES in the example) as well as the scripts that drive it's own internal node workings (called 3dlsystem.py).
The code for these things is available from github.
So what can it make?Tragically I've not had much time to play with it, i'm hoping others might find it useful. As proof that It does work i'll include a few Rule sets.
with t_angle set to 0.02 it looks like grass in the wind..
