Struct AtmosphereParameters 

pub struct AtmosphereParameters {
    pub kind: AtmosphereKind,
    pub seed: u32,
    pub color: Color,
    pub opacity: f64,
    pub intensity: f64,
    pub scale: f64,
    pub drift: [f64; 2],
    pub fractal: Fractal,
}

Editable unvalidated atmospheric parameters; paint construction validates all fields.

Fields

kind: AtmosphereKind

Envelope and effect-specific parameters.

seed: u32

Explicit noise and mote seed.

color: Color

Straight encoded-sRGB tint.

opacity: f64

Alpha/density multiplier in 0..=1.

intensity: f64

Straight-linear RGB multiplier in 0..=64.

scale: f64

Noise wavelength or dust-cell spacing in pixels, in 0.25..=1000000.

drift: [f64; 2]

Pattern velocity in canvas pixels per second.

fractal: Fractal

Amplitude-normalized fractal parameters, with at most eight octaves.

Implementations

impl AtmosphereParameters

pub fn validate(&self) -> Result<(), ValidationError>

Rejects nonfinite, unsupported or out-of-range recipe parameters.

pub fn sample( &self, pixel: [f64; 2], canvas: PixelSize, phase: [f64; 2], ) -> Result<[f64; 4], ValidationError>

Evaluates straight linear RGBA at an explicit canvas pixel coordinate.

The caller supplies canvas dimensions and advection phase; image generators and independent paint backends use these same mathematical definitions.

Trait Implementations

impl Clone for AtmosphereParameters

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for AtmosphereParameters

impl Debug for AtmosphereParameters

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

Formats the value using the given formatter.

impl PartialEq for AtmosphereParameters

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
