procedural-gl.js

Procedural GL JS is a library for creating 3D map experiences on the web, written in JavaScript and WebGL. It is built on top of THREE.js.

It provides an easy-to-use, but powerful framework to allow beautiful landscapes of the outdoors to be embedded into web pages. It loads super-fast and is optimized for mobile devices.

Key features

  • Novel GPU powered level-of-detail system gives butter-smooth rendering, including on mobile
  • Stream in standard raster imagery tiles. Supports map tiles from a variety of providers
  • Easily include elevation data. Global 3D data integration via nasadem.XYZ
  • Powerful overlay capabilities. Draw crisp markers and lines
  • Well-thought-out API, complex applications can be built without needing to deal with 3D concepts
  • Great UX and intuitive controls, mouse-based on desktop & touch-based on mobile
  • Tiny filesize means library is parsed fast. Package size is less than THREE.js thanks to code stripping

Install

npm install procedural-gl

Usage

import Procedural from 'procedural-gl';

// Choose a DOM element into which the library should render
const container = document.getElementById( 'container' );

// Configure datasources
const datasource = {
  elevation: {
    apiKey: 'GET_AN_API_KEY_FROM_www.nasadem.xyz'
  },
  imagery: {
    apiKey: 'GET_AN_API_KEY_FROM_YOUR_IMAGERY_PROVIDER',
    urlFormat: 'https://imagery.example.com/tiles/{z}/{x}/{y}.jpg?key={apiKey}',
    attribution: 'Imagery attribution'
  },
};

// Initialize library and optionally add UI controls
Procedural.init( { container, datasource } );
Procedural.setRotationControlVisible( true );

// Load real-world location
const montBlanc = { latitude: 45.8326364, longitude: 6.8564201 };
Procedural.displayLocation( montBlanc );
