Chain it and you build a tree a level at a time: trunk, then limbs, then branches, then twigs. Everything is expressed as a ratio of the parent, so the whole structure scales together when the trunk changes.
Tropism is what aims it. Pointing up gives a tree, down gives roots, sideways and untapered gives something that spreads like fungus or coral. That one setting changes what the structure reads as more than any other.
Inputs
| Socket | Type | Wiring |
|---|---|---|
| curve | geometry | |
| tropism | vector | one wire covers tropismX, tropismY, tropismZ |
These settings are also output sockets, so another part can read the number instead of repeating it: count, angle, lengthRatio, radiusRatio.
