Struct WindField 

pub struct WindField { /* private fields */ }

The CPU-side wind field. Holds the authoring values plus a running clock.

sample(world_pos) returns the same vector the GPU helper produces for a vertex at the same position, so spring bones, particles, and cloth see a consistent field.

Implementations

impl WindField

pub fn new(authoring: WindAuthoring) -> Self

Build a field from authoring values, starting the clock at zero.

pub fn set_authoring(&mut self, authoring: WindAuthoring)

Replace the authoring values. The clock is preserved so a runtime tweak does not snap the field discontinuously.

pub fn authoring(&self) -> WindAuthoring

Current authoring values.

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

Advance the clock by dt seconds.

pub fn reset(&mut self)

Reset the clock to zero. Authoring values are preserved.

pub fn time(&self) -> f32

Current clock value.

pub fn sample(&self, world_pos: Vec3) -> Vec3

Sample the wind at a world-space position. Matches the WGSL helper formula in crate::SHARED_WIND_WGSL.

pub fn to_globals(&self) -> WindGlobals

Pack the field into the GPU uniform layout.

pub fn to_slot_params(&self) -> [[f32; 4]; 4]

Pack the field into the four vec4<f32> slot-params words that the deformer body reads from deform_header.slot_params[slot * 4 .. + 4].

Layout:

• [0] = (direction.x, direction.y, direction.z, base_strength)
• [1] = (gust_strength, gust_frequency, spatial_density, time)
• [2] / [3] are reserved for future use.

Trait Implementations

Performs copy-assignment from source.

impl Debug for WindField

fn fmt(&self, f: &mut Formatter<'_>) -> Result
