Cesium - WebGL Virtual Globe and Map Engine

Cesium requires WebGL, an open standard for displaying 3D content in a web browser. Unfortunately, your browser does not appear to support WebGL. Internet Explorer users can install the Chrome Frame plug-in, otherwise try a WebGL-compatible browser, such as Chrome or Firefox. For the best experience, it is recommended to update your video card drivers (NVIDIA | AMD) as well.

Cesium is a JavaScript library for creating 3D globes and 2D maps in a web browser without a plugin. It uses WebGL for hardware-accelerated graphics, and is cross-platform, cross-browser, and tuned for dynamic-data visualization. Cesium is open source under the Apache 2.0 license. It is free for commercial and non-commercial use.

Blog

The Cesium blog contains project announcements and technical content on Cesium and the technologies used to implement it.

One API, Three Views

Cesium supports a 3D globe, 2D map, and 2.5D Columbus View with the same API. Transition between views with one line of code.

Dynamic Geospatial Data Visualization

Animate time dynamic scenes from CZML.
Visualize worldwide terrain from multiple sources.
Draw imagery layers using WMS, TMS, OpenStreetMaps, Bing, and Esri standards.
Draw vector data from KML and ESRI Shapefiles.

Built for Precision and Performance

Draw polylines, polygons, circles, icons, labels, and custom objects. Use the material system to change their appearance.
Control the camera and create flight paths.
Use low-level geometric and rendering routines.

Cesium is an open-source project started by Analytical Graphics, Inc. It is starting to grow to a broader community of contributors.
