This scene depicts autumn leaves detaching from trees and tumbling to the ground in a park, driven by a gentle prevailing wind. Each leaf is an instance of a bezier-curved leaf shape that falls, sways side to side, and spins on multiple axes as it descends, eventually settling as litter on the ground.
- 2,600 falling leaves + 900 ground-litter leaves rendered via
InstancedMesh with per-instance colors
- Each leaf has independent fall speed, sway amplitude/frequency, and spin phase
- Wind adds a shared sinusoidal horizontal drift on top of individual sway
- Five-color autumn palette (orange, gold, crimson, amber) randomly assigned per leaf
- Camera auto-orbits the park scene when idle; drag to explore manually
