Analytical Graphics Inc. (AGI) and Bentley Systems announce Bentley Systems as a co-founder of the new Cesium Consortium. Cesium is an open source, browser-based virtual globe, first developed by AGI in 2011 for the aerospace and defense communities. Cesium’s unparalleled performance in streaming very large datasets through a browser to desktops, tablets, and smart phones has enabled it to become the virtual globe of choice for geospatial viewing. The consortium will now enable AGI and Bentley to collaborate on the Cesium roadmap to better accelerate and support the requirements for building infrastructure modeling (BIM) and for owners of infrastructure assets. In addition, the consortium will support feature development, priority bug fixes, expansion of outreach efforts, and the hosting of social coding events such as code sprints and bug bashes. Bentley Systems is adopting Cesium to visualize and interact with highly detailed infrastructure engineering models set in the reality context of their surrounding environment. The digital engineering models are created with Bentley’s MicroStation and BIM applications, and the context is provided through reality meshes, created from digital photography and scanning devices using Bentley’s ContextCapture. Bentley’s work to date illustrates the advantages that the infrastructure community can expect from Cesium. Data created with both MicroStation and ContextCapture can be exported to 3D Tiles, an open format developed by the Cesium team to stream massive geo-coordinated 3D datasets. Cesium will enable Bentley users to stream their digital engineering models over the Web to desktop and mobile devices with unprecedented performance and precision.
