Users today leverage a variety of products, tools and data to solve increasingly complex problems. Workflows will vary from project to project. Combining a BIM model from tool 1, civil engineering data from tool 2, reality capture from tool 3, GIS data from tool 4 and 3D context from tool 5 becomes even more complex. Using open standards, like OGC 3D Tiles, and interoperable tools, like open visualization clients, simplify these complex data wrangling workflows to accelerate value for the Community. Example - HNTB leverages multiple products to design a new bridge or roadway, including Civil3D, Revit, OpenRoads. They use Cesium to bring this data together, along with Google P3DT to create immersive digital twins within Unity and Unreal for their end users. They selected Cesium for Unity and Cesium Unreal as their visualization clients because they are open source and reduced their average project development by 70% If we want to ensure we continue making the complex simple for developers & users within the 3D and Geospatial communities, openness and interoperability of data and software will be the keystone. https://cesium.com/blog/
