WebGL Wind

A WebGL-powered visualization of wind power. Capable of rendering up to 1 million wind-led 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

Downloading weather data

1. Install GRIB-API.
2. Edit constants in data/download.sh for desired date and resolution.
3. Run ./data/download.sh <path> to generate wind data (<path>.png and <path>.json) for use with the library.
4. Optionally run optipng -o7 <path>.png to reduce the wind texture file size.
