Dither Free WebGPU shader

Less color. More character.

An ordered Bayer dithering background for React. Adjust tone levels and pixel cell size, then export the animated WGSL effect.

THE SYSTEM BEHIND THE SURFACE

Inside Dither.

Dither quantizes a generated field through a computed 4×4 Bayer matrix. Levels controls the tonal steps, while cell size is measured in device pixels.

This is ordered dithering of a procedural field, not error-diffusion image processing. Device-pixel sizing can look different at different DPR values.

0.426 ms legacy timing (method not recorded; not a pure GPU measurement). 1440x900 @ dpr 2; Metal driver on macOS Version 26.6.2 (Build 25G83); measured 2026-09-02. This is a recorded headless sample, not a browser FPS or mobile-performance guarantee.

Levels

How many tones the field is crushed to. Fewer is more graphic.

Pattern size

Bayer cell size in device pixels.

Dither

At zero the tones band; the threshold is what trades banding for texture.

Field scale

Density of the soft waves behind the dither; higher values make them smaller.

Color Looks preserve these settings. Open the editor for all 10 controls.

KEEP THE SOURCE. KEEP THE CONTROL.

From preview to your project.

Choose a Look, tune it in the editor, then download the Export Kit. Install the runtime and copy the generated component into your project.

Every control in the editor is a typed prop. Leave a prop out to keep the value you exported; change one and the running shader updates without restarting. Give the surface a size and pass fallback for browsers without WebGPU.

In Next.js, use a client component and give its container an explicit size. Keep headings, links and accessible content in HTML above the decorative canvas.

Markdown guide

Usage example — download Dither.tsx from the editor first. This example imports that local file; it is not the shader component itself.

Terminal

npm install ./vendor/aperveil-runtime-0.1.0.tgz ./vendor/aperveil-react-0.1.0.tgz

Dither usage

"use client";

import Dither from "./Dither";

export default function Hero() {
  return (
    <Dither
      className="hero-shader"
      levels={6} shadowColor="#12101fff"
      fallback={<div className="hero-shader-fallback" />}
    />
  );
}

// .hero-shader { width: 100%; height: 560px; }

Download and extract the complete Export Kit first. Run its local package command from the ZIP root, then copy the component into your project. Public npm and CLI distribution is coming soon.
