Cesium for Unreal Now Available

Business Model

Community success is at the core of Cesium’s DNA. We believe that significant and sustained contributions to the ecosystem create lasting value and advance our craft faster than a pure-play proprietary model. As such, Cesium for Unreal is free and open source under the liberal Apache 2.0 license. Cesium ion is an optional commercial service that provides real-world 3D content and 3D tiling pipelines, which supports funding our open source development.

This business model is called an open-core business model and is sometimes used where commodity software is made open source to support potential interest in value-add commercial software. Cesium for Unreal is anything but commodity, so we are a bit extreme in the openness of our model. We believe this openness will facilitate rapid collaborative innovation and create collective community success, while giving our business the opportunity to grow based on merit and delivering valuable services. This is the way business should be done.

The Cesium Platform

Cesium for Unreal is a complement to CesiumJS, our open source purpose-built 3D engine for the web. We are advancing both engines in parallel and cross-leveraging our efforts; for example, by advancing 3D Tiles and glTF specifications, by utilizing Cesium ion services, and by simply applying lessons learned on topics such as high-precision rendering and 3D Tiles streaming optimizations.
