Map Input to Output

Use separate buffers when you want to keep the input unchanged.

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

const v = await volten();

const input = new Buffer([1, 2, 3, 4], 'f32', 'r');
const output = new Buffer([0, 0, 0, 0], 'f32', 'rw');

const doubleValues = new Kernel(`
  fn main(gid: vec3u) {
    output[gid.x] = input[gid.x] * 2.0;
  }
`);

const node = v.pass(doubleValues, { input, output });
v.run(node);

console.log(await v.read(output));
// Float32Array [2, 4, 6, 8]
