Struct TurbulenceForce 

pub struct TurbulenceForce {
    pub strength: f32,
    pub frequency: f32,
    pub time_offset: f32,
}

Pseudo-random turbulence force using a curl-noise-like field.

Uses a deterministic hash to approximate a divergence-free velocity field, giving swirling motion without requiring full Perlin noise.

Fields

strength: f32

Turbulence strength (max velocity perturbation per second).

frequency: f32

Spatial frequency of the noise field.

time_offset: f32

Time offset (varies the noise over time).

Implementations

impl TurbulenceForce

pub fn new(strength: f32, frequency: f32) -> Self

Create a new turbulence force.

pub fn advance(&mut self, dt: f32)

Advance the internal time offset.

pub fn curl_at(&self, pos: [f32; 3]) -> [f32; 3]

Compute curl-noise-like perturbation at a world position.

Approximates curl(noise_field) using finite differences.

pub fn apply(&self, particle: &mut GpuParticle, dt: f32)

Apply turbulence to a single particle.

pub fn apply_all(&self, particles: &mut [GpuParticle], dt: f32)

Apply turbulence to all alive particles.
