Struct WaveFormationState

pub struct WaveFormationState {
    pub phase_time: f32,
    pub idle_time: f32,
    pub fibonacci_blend: f32,
    pub amplitude: f32,
    pub frequency: f32,

}

Expand description

Per-particle wave formation state. Pre-allocated, updated every frame. Drives the visual shape of the particle using real wave equation math.

Fields§

§phase_time: f32

Cumulative phase time (seconds). Drives ω·t in the wave equation.

§idle_time: f32

Time spent in current idle (seconds). Drives idle→Fibonacci decoherence.

§fibonacci_blend: f32

Blend from wave(0.0) to Fibonacci(1.0). Uses exp(-Γ·t_idle).

§amplitude: f32

Wave amplitude A. Scales with velocity for weighty feel.

§frequency: f32

Wave frequency f (Hz). Higher = faster ripple.

§wavelength: f32

Wavelength λ. Controls spatial density of ripples.

§heading: [f32; 2]

Heading direction [x, z] normalized. Wave propagates along this axis.

§offsets: Vec<[f32; 3]>

Pre-computed particle offsets for current frame. Reused by GPU upload.

Implementations§

impl WaveFormationState

pub fn new(particle_count: u32) -> Self

pub fn update( &mut self, speed: f32, heading: [f32; 2], yaw: f32, dt: f32, particle_count: u32, radius: f32, )

Update wave formation from controller state. speed: current movement speed (0 = idle). heading: normalized [x, z] movement direction. dt: frame delta time.
