Dither Gradient
Smooth gradients decomposed into shifting ordered dithering patterns with chromatic separation and bit-depth waves.
What is Dither Gradient?
Dither Gradient is a free WebGL web effect in the TappyPrism library. Smooth gradients decomposed into shifting ordered dithering patterns with chromatic separation and bit-depth waves. It is rendered on the GPU by a fragment shader, so it costs almost nothing on the CPU and works well as a full-screen background. It ships as a single self-contained HTML file (dither-gradient.html) with zero dependencies — no npm package, no framework, no build step. It exposes 2 live parameters — Dither Scale, Bit Depth — adjustable in the browser or at runtime.
Parameters
| Parameter | Key | Range | Default |
|---|---|---|---|
| Dither Scale | DITHER_SCALE | 0.5 – 3 | 1 |
| Bit Depth | BIT_DEPTH | 0.3 – 2 | 1 |
How to add Dither Gradient to your page
- Download the standalone file dither-gradient.html and copy its source into your project.
- Or embed it as a background iframe:
<iframe src="https://prism.tappypotato.com/fx/dither-gradient.html" style="position:fixed;inset:0;width:100%;height:100%;border:0;z-index:-1" title="Dither Gradient"></iframe> - Tune it at runtime with postMessage:
iframe.contentWindow.postMessage({ type: 'param', name: 'DITHER_SCALE', value: 1 }, '*');
