// GALE GROVE — the wind SIM FIELD driving L-SYSTEM trees: the same
|
|
// `wind_field:` opt-in as the meadow, on branching geometry. The field is
|
|
// sampled at each vertex's REST position, so parent and child branches
|
|
// read the same wind at their joint and can never tear; gusts light what
|
|
// they bend, so a kick sends a visible shudder traveling through the
|
|
// grove. Pattern taught here: one wind field, any mesh engine.
