WebGL Globe

Examples: https://storage.googleapis.com/ubilabs-webgl-globe/examples/index.html

Description

A 3D Globe library for rendering raster tiles in equirectangular projection for the 'Climate from space' app and website.

Features:

• Interactive 3D globe with basic user interaction for panning and zooming
• Support for multiple layers (e.g. base map and dataset)
• Support for single image (typically 2048x1024px) and tiled (256px tilesize) datasets
• Support for HTML Markers
• External camera-controls
• As the library and rendering is relatively efficient, it is possible to render several globes side-by-side on the same page
• Support for smooth blend over between different datasets and timesteps.
• Tile loading and data handling optimized for animated datasets.
• lightweight bundle: ~120kb gzipped

Installation

IMPORTANT: as this is a pre-release version, it has not yet been published to npm and usage as a module has not yet been tested.

Usage

import {WebGlGlobe} from '@ubilabs/esa-webgl-globe';

const globe = new WebGlGlobe(domElement, {
  layers: [{
    id: 'basemap',
    zIndex: 0,
    maxZoom: 4,
    getUrl: ({x, y, zoom}) =>
      `https://storage.googleapis.com/esa-cfs-tiles/1.9.0/basemaps/dark/${zoom}/${x}/${y}.png`
  }]
});

Contributing

We are generally happy to accept contributions from outside collaborators. If you are interested in contributing to the project, please use the issue-tracker to open a feature-request and discuss your ideas with us before starting the implementation. This is to save us all from having to reject pull-requests for being out of scope or not being aligned with internal goals for this project.

Development

For development, you need to have a working git-client and nodejs available. After cloning the repository, install the development dependencies using:

npm install

After that, you can start the vite development-server, which will serve the examples in ./examples via http://localhost:5173/.

npm start

Publishing / Deployment

Examples

The example files are built and copied to a Google Cloud Storage Bucket (requires properly configured installation of gcloud / gsutil and an account with write access) using the deploy:examples npm-task.

npm run deploy:examples
