Underground, TypeScript, and Global 3D Buildings in CesiumJS 1.70

CesiumJS 1.70 is now out: https://github.com/CesiumGS/cesium/releases/download/1.70/Cesium-1.70.zip

Full changelog.

This release comes with 3 major announcements. Let us know what you think or if you have any questions in this thread!

Cesium OSM Buildings

Cesium OSM Buildings is a 3D buildings layer covering the entire world built with OpenStreetMap data. It’s available as a 3D Tileset for all Cesium ion users and comes with rich per-feature data like building name, address, opening hours, and much more.

Underground Support

We now have better support for visualizing underground scenes, from large geological layers underneath the Earth to mines, caves, and utilities. CesiumJS 1.70 adds the ability to make the globe transparent to visualize the data underneath, and allow the camera to freely go underground.

TypeScript

CesiumJS now ships with official TypeScript type definitions! The most up-to-date and correct definition files will now ship with each new release, and TypeScript support will be officially tracked as part of the CesiumJS GitHub repository.

@omar official Typescript definitions rock :metal: ! I have noticed many people have started contributing to the project after this announcement with fixes around documentation and Typescript. This type of engagement is very good for the community :pray:

Absolutely! Even though I don’t use TypeScript in my day-to-day it’s very cool seeing this effort expose all these documentation issues and get all these contributions from different folks. And big thanks to @Matt_Amato for coordinating a lot of this effort!

Thanks, everyone!

On that note, I’m excited to announce the release of CesiumJS 1.70.1, a patch release that mainly incorporates the feedback and pull requests we’ve received from our Typescript community. Get it from npm or our downloads page: https://cesium.com/downloads/
