Wind power visualization with WebGL particles

WebGL Wind — Demo

A WebGL-powered visualization of wind power. Capable of rendering up to 1 million wind particles at 60fps.

This project is heavily inspired by the work of:

• Cameron Beccario and his wonderful Earth project with its open-source version.
• Fernanda Viégas and Martin Wattenberg and their US Wind Map project.
• Chris Wellons and his WebGL tutorials, in particular A GPU Approach to Particle Physics.
• Greggman and his WebGL Fundamentals guide.

Running the demo locally

npm install
npm run build
npm start
# open http://127.0.0.1:1337/demo/

Downloading weather data

1. Install ecCodes (e.g. brew install eccodes).
2. Edit constants in data/download.sh for desired date, time and resolution.
3. Run ./data/download.sh demo/wind 20210627 00 to generate wind data files (png and json) for use with the library.
4. Modify the windFiles, object in demo/index.js to reference the new dataset
   1. Object keys are offsets in hours from the first date/time
   2. The label for the GUI control is in the meta object
   3. The min, max, and interval for the GUI control are on the gui.add(meta, ...) line
