Enum ProceduralSprite 

pub enum ProceduralSprite {
    SoftCircle,
    Smoke {
        scale: f64,
        evolution: f64,
        fractal: Fractal,
    },
    Star,
    Ring,
    FireCore,
}

Built-in image materials requiring no external assets.

Variants

SoftCircle

Radial soft circular material.

Smoke

Seeded smoke: spatial fBm over a time-evolving three-dimensional Perlin field.

Fields

scale: f64

Positive spatial scale in normalized sprite coordinates, in 0.25..=64.

evolution: f64

Signed time evolution speed.

fractal: Fractal

Bounded spatial octave recipe.

Star

Cross-shaped star highlight.

Ring

Soft annular material.

FireCore

Vertically elongated warm fire core.

Implementations

impl ProceduralSprite

pub fn generate( self, size: u32, seed: u64, ) -> Result<Arc<ImageAsset>, ValidationError>

Builds a finite linear sprite; size is 2..=512 and all noise uses an explicit seed.

pub fn generate_at( self, size: u32, seed: u64, time: Time, limits: RasterLimits, ) -> Result<Arc<ImageAsset>, ValidationError>

Builds a sprite at explicit time after pixel, mip storage and work admission. Only Smoke depends on time; the other materials are static.

Trait Implementations

impl Clone for ProceduralSprite

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 ProceduralSprite

impl Debug for ProceduralSprite

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

Formats the value using the given formatter.
