JavaScript Library to create 3D globes and 2D maps

An Open Source JavaScript API that allows creating 3D globes and 2D shapes in a web browser without a plugin

CesiumJS is an open-source lightweight JavaScript library that allows JavaScript developers to create 3D globes and 2D maps in a web browser without a plugin. The API is designed to deliver the best possible performance, precision, visual quality, and ease of use. It uses WebGL for hardware-accelerated graphics, and is cross-platform, and tuned for dynamic-data visualization. Furthermore, the API allows cross-browser support and you can use your application in any browser.

CesiumJS streams 3D content such as terrain, imagery, and 3D Tiles from the commercial Cesium ion platform and other content sources. The API is free to use and you can use it for both commercial and non-commercial use.

The API also allows multiple views at the same time. You can view your data in 3D, 2D, and 2.5D columbus view and switch between three different map modes at runtime. If you want two views to be synced across time, you can create a shared clock object that both views share.
