force.turbulence
A per-agent jitter that keeps a 3D swarm alive, scaled by params.agitation.
force.turbulence(
layout: VolumeSwarmLayout,
cfg: {posScale: number; timeX: number; timeY: number; seedScale: number; gain: number},
): AgentForce3
Import sim from shaders/std and use sim.agentForces.force.turbulence.
Parameters
| Name | Type | Notes |
|---|---|---|
layout | VolumeSwarmLayout | |
cfg | {posScale: number; timeX: number; timeY: number; seedScale: number; gain: number} |
Example
forces: [pressure.force, force.turbulence(simLayout, {posScale: 193, timeX: 31.7, timeY: 27.3, seedScale: 997, gain: 5})]
Tip. Keep the scale constants large. Small ones make the noise smooth and the whole swarm drifts in step.
