Uniform Parameters

Use a Uniform for small values that affect every invocation.

import { volten, Buffer, kernel, Uniform } from '@volten/core';

const v = await volten();
const data = new Buffer([1, 2, 3, 4], 'f32', 'rw');
const multiplier = new Uniform(10, 'f32');

const scale = kernel({
    shader: `
  fn main(gid: vec3u) {
    data[gid.x] = data[gid.x] * multiplier;
  }
`
});

const node = scale({ data, multiplier });
v.run(node);

console.log(await v.read(data));
// Float32Array [10, 20, 30, 40]

Uniforms are a good fit for scalars, vectors, and small parameter structs.
