Shattered Plains
Storm-carved chasms branching through ancient sandstone plateaus with depth-revealed strata.
What is Shattered Plains?
Shattered Plains is a free WebGL web effect in the TappyPrism library. Storm-carved chasms branching through ancient sandstone plateaus with depth-revealed strata. 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 (shattered-plains.html) with zero dependencies — no npm package, no framework, no build step. It exposes 3 live parameters — Channel Speed, Channel Depth, Grain Texture — adjustable in the browser or at runtime.
Parameters
| Parameter | Key | Range | Default |
|---|---|---|---|
| Channel Speed | CHANNEL_SPEED | 0.1 – 2 | 0.5 |
| Channel Depth | CHANNEL_DEPTH | 0.3 – 2 | 1 |
| Grain Texture | GRAIN | 0 – 2 | 1 |
