Crystal Lattice
Procedural crystal formations growing with faceted 3D lighting and prismatic sparkle.
What is Crystal Lattice?
Crystal Lattice is a free WebGL web effect in the TappyPrism library. Procedural crystal formations growing with faceted 3D lighting and prismatic sparkle. 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 (crystal-lattice.html) with zero dependencies — no npm package, no framework, no build step. It exposes 4 live parameters — Crystal Count, Prismatic, Tilt X, Tilt Y — adjustable in the browser or at runtime.
Parameters
| Parameter | Key | Range | Default |
|---|---|---|---|
| Crystal Count | GROWTH_SPEED | 0.3 – 2 | 1 |
| Prismatic | REFRACTION | 0 – 2 | 1 |
| Tilt X | TILT_X | -1.5 – 1.5 | 0 |
| Tilt Y | TILT_Y | -0.5 – 0.5 | 0 |
How to add Crystal Lattice to your page
- Download the standalone file crystal-lattice.html and copy its source into your project.
- Or embed it as a background iframe:
<iframe src="https://prism.tappypotato.com/fx/crystal-lattice.html" style="position:fixed;inset:0;width:100%;height:100%;border:0;z-index:-1" title="Crystal Lattice"></iframe> - Tune it at runtime with postMessage:
iframe.contentWindow.postMessage({ type: 'param', name: 'GROWTH_SPEED', value: 1 }, '*');
