SandTable Viewer

A lightweight web app to visualize and simulate .thr (theta-rho) files for polar sand tables like Sisyphus or Oasis.

👉 Live Demo

Features

• Preview .thr files: Load any .thr track and see the full path immediately.
• Ball Simulation: Real-time animation of the ball tracing the polar coordinates.
• RGB Mode: Visualize path density and angles with dynamic RGB coloring or classic monochrome sand mode.
• Zero setup: Runs entirely in the browser using HTML5 Canvas.

Usage

Use the online version directly, or run it locally:

1. Clone or download the repo and open index.html in any modern browser.
2. Click Upload .thr File and select any .thr track (you can use reverse-HEP.thr included in this repo as a sample).
3. Toggle View Full Path to display the entire pattern at once.
4. Toggle Use RGB Path to switch between color-mapped paths and classic sand beige.
