Tesseract Shadow
4D hypercube projected into 2D with depth-faded wireframe, axis-mapped colors, and rotation trails.
What is Tesseract Shadow?
Tesseract Shadow is a free Canvas 2D web effect in the TappyPrism library. 4D hypercube projected into 2D with depth-faded wireframe, axis-mapped colors, and rotation trails. It is drawn with the Canvas 2D API, which trades some GPU efficiency for the widest possible browser and device support. It ships as a single self-contained HTML file (tesseract-shadow.html) with zero dependencies — no npm package, no framework, no build step. It exposes 2 live parameters — Rotation Speed, Projection Depth — adjustable in the browser or at runtime.
Parameters
| Parameter | Key | Range | Default |
|---|---|---|---|
| Rotation Speed | ROTATION_SPEED | 0.05 – 1 | 0.3 |
| Projection Depth | PROJECTION_DEPTH | 0.3 – 2 | 1 |
How to add Tesseract Shadow to your page
- Download the standalone file tesseract-shadow.html and copy its source into your project.
- Or embed it as a background iframe:
<iframe src="https://prism.tappypotato.com/fx/tesseract-shadow.html" style="position:fixed;inset:0;width:100%;height:100%;border:0;z-index:-1" title="Tesseract Shadow"></iframe> - Tune it at runtime with postMessage:
iframe.contentWindow.postMessage({ type: 'param', name: 'ROTATION_SPEED', value: 0.3 }, '*');
