Cesium for Unreal coming March 30

Hi everyone,

We’re thrilled to announce that Cesium for Unreal will be released as open source, under Apache 2.0 License, on March 30, 2021. With 3D Tiles and Cesium for Unreal, we are unlocking 3D geospatial content to decades of innovation in game engine technology. We are bringing a full-scale high-accuracy WGS84 globe to Unreal Engine, and creating an end-to-end workflow for geospatial content powered by 3D Tiles and Cesium ion.

What does this mean for CesiumJS? CesiumJS will continue to be the best-in-class purpose-built open source WebGL engine for web-based geospatial applications and will continue to receive Cesium support and development backing. At the same time, Cesium for Unreal plugin expands the 3D geospatial ecosystem to include game engine visuals and tools.

We strongly believe that the success of Cesium lies in its developer community and open ecosystem, and we can’t wait to see all that you build with Cesium for Unreal.


We’re so excited about this! Let us know if you have questions or ideas for what you’ll create with Cesium for Unreal.

What programming language and development environment are used?

Unreal Engine plugins use C++, with Visual Studio on Windows, and clang on Linux.

You can read more about developing with Unreal here: https://docs.unrealengine.com/en-US/ProgrammingAndScripting/ProgrammingWithCPP/index.html/.

Also, you can use an emscripten tool chain to compile it for the browser. That’s what we are doing, though the results are way bigger than current Cesium (~90 mb). Of course that is to be expected with all the features, current Cesium works better for the web for now.
