Shader Catalog

The shader registry is a collection of small, pure WGSL functions you can pull into any Shader by slug. They’re not full programs — they’re the parts you’d otherwise rewrite every project: SDFs, noise fields, easing curves, post-processing kernels, lighting models, hashes, palettes, projections.

Compose them into a shader with Shader::new:

let main = r#"
@fragment fn fs_main(in: VertexOutput) -> @location(0) vec4<f32> {
    let n = simplex2(in.uv * 6.0);
    let v = vignette(in.uv, 0.55, 0.40);
    return vec4<f32>(vec3<f32>(n * v), 1.0);
}
"#;
let shader = Shader::new(&[
    "noise/simplex2",
    "postfx/vignette",
    main,
])?;

Shader::new fetches each slug (the registry is embedded by default — see the network feature for fetching at runtime), validates the combined source with naga, and emits one ready-to-render program. Slugs are content-addressed, so importing the same helper from two different shaders compiles it once.
