A procedurally generated city built with WebGL and three.js

City Tour

Visit a procedurally generated city, different each time. Sit back and enjoy the ride!

Made using three.js and WebGL.

How It Works

First, blueprints of the world are generated:

• A terrain map
• A road network that follows the terrain
• Empty building lots along roads
• Buildings in the lots

The results are different each time due to random variation, but follow configurable rules.

Next, this abstract definition is turned into a 3D model that can be rendered with WebGL, with the help of three.js.

Once this is all created, you can move around the city using touch gestures (mobile) or the mouse (desktop). Navigation works similar to Google/Apple Maps. You can also click the "Take a Tour" button to go on an automatic flight/drive through the city.

Running Locally

• If running the app locally for the first time, run yarn install
• Run yarn serve, which will build the app and start a local development server
• Open the localhost URL listed in the command-line output in your browser
• If a source file is changed while the server is running the app will automatically be rebuilt. However, you'll need to manually refresh the page in your browser to see the changes.

Building For Production

• If building the app for the first time, run yarn install
• Run yarn build
• The dist/ folder will contain the files that should be deployed to production

Running Tests

• yarn test
