# PCTE-threejs-editor — ready to run

Built from `PCTE-rewrite/threejs-editor` on 2026-10-05. Requires Python 3.8+ and a current desktop browser with WebGL 2. Node.js, npm and an internet connection are not needed to run this build.

Linux/macOS:

```sh
./launch.sh
```

Windows: run `launch.cmd` (Python 3 must be installed). On any platform, `python3 serve.py` works; Windows can use `py -3 serve.py`. The launcher opens the browser at the printed loopback URL. Keep the terminal open; Ctrl+C stops it. To select a port or avoid opening the browser, use `python3 serve.py --port 8870 --no-browser`.

Use **File → New project…**, create a small project, then inspect it in Top and Perspective views. Runtime exports are under **File → Export**.

For ordinary static hosting, publish only the contents of `site/`. Relative resource URLs also support hosting beneath a subdirectory. Serve over HTTP/HTTPS; opening index.html directly from disk is not supported.
