Struct HumidityMap 

pub struct HumidityMap {
    pub width: usize,
    pub depth: usize,
    pub data: Vec<f32>,
}

A 2-D humidity map over the simulation grid.

Fields

width: usize

depth: usize

data: Vec<f32>

Relative humidity [0.0, 1.0] stored row-major (z * width + x).

Implementations

impl HumidityMap

pub fn new(width: usize, depth: usize, base: f32) -> Self

pub fn sample(&self, gx: f32, gz: f32) -> f32

Sample humidity at continuous grid coords using bilinear interpolation.

pub fn set(&mut self, gx: usize, gz: usize, val: f32)

Set humidity at integer grid cell.

pub fn advect(&mut self, dx: f32, dz: f32)

Advect humidity by a uniform wind (dx, dz) in grid cells/step.

pub fn evaporate(&mut self, rate: f32)

Evaporation — increase humidity by rate everywhere (capped at 1.0).

pub fn precipitate(&mut self, sat: f32, coeff: f32)

Precipitation sink — decrease humidity proportional to excess above sat.

Trait Implementations

impl Clone for HumidityMap

fn clone(&self) -> HumidityMap

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for HumidityMap

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

Formats the value using the given formatter.
