CesiumJS Triply Demo

This is a proof-of-concept demo based on the provided research. It demonstrates:

1. Initializing a CesiumJS Viewer.
2. Loading vector data (simulating Triply API output) from a GeoJSON file.
3. Using a Clipping Plane to create a cross-section view (for underground visualization).

How to Run

Because this demo loads an external data file (stub_data.geojson), you cannot simply open the index.html file in your browser due to security restrictions (CORS). You must run a local web server.

Using npx (Node.js)

If you have Node.js installed, run:

npx serve .

Then open the URL shown (usually http://localhost:3000).

Using Python

Alternatively, if you have Python installed:

python3 -m http.server

Then open http://localhost:8000.
