Struct Atmosphere 

pub struct Atmosphere { /* private fields */ }

Editable bounded recipe; sampling retains no playback or random state.

The parameters are shared with the core paint, and the recipe dereferences to them so fields such as opacity remain directly editable. This type adds presets, baking and blend-mode selection.

Implementations

impl Atmosphere

pub const fn new(parameters: AtmosphereParameters) -> Self

Wraps explicit parameters; they are validated when the recipe is painted or rendered.

pub fn fog(seed: u32) -> Self

A pale, low-contrast fog layer, denser near the bottom edge.

pub fn dust(seed: u32) -> Self

Sparse warm HDR dust, suitable for Plus or Screen composition.

pub fn light_leak(seed: u32) -> Self

Warm HDR light entering from the left edge.

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

Validates the full recipe before noise evaluation or allocation.

pub fn paint( &self, canvas: PixelSize, time: Time, ) -> Result<AtmospherePaint, ValidationError>

Captures the same recipe as an independently evaluated CPU/GPU paint.

Canvas pixels determine wavelength, drift and envelope coordinates; painted shape bounds map to that canvas. This does not bake or allocate an image.

pub fn blend_mode(&self) -> BlendMode

Blend mode that composes this recipe without darkening: Screen for fog, Plus for HDR light.

pub fn overlay( &self, size: PixelSize, time: Time, limits: RasterLimits, ) -> Result<Node>

Renders the recipe at an explicit time into a bilinear-sampled node using Self::blend_mode. The node has the pixel size as its design size, so it fills a canvas of the same dimensions.

pub fn render( &self, size: PixelSize, time: Time, limits: RasterLimits, ) -> Result<ImageAsset>

Generates a full image at explicit time after pixel, byte and work admission.

pub fn render_region( &self, canvas: PixelSize, origin: [u32; 2], size: PixelSize, time: Time, limits: RasterLimits, ) -> Result<ImageAsset>

Generates a base-level region using full-canvas envelope and global pixels. Adjacent regions match full-image base texels exactly; mipmaps are regional.

Methods from Deref<Target = 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.
