Open Standards & Formats
When it comes to visualizing diverse geospatial data, in real time, Cesium is breaking new ground. We've adopted open formats wherever they were available, and we've developed open formats where they weren't, setting the standard for open 3D geospatial formats.
A specification for streaming massive heterogeneous 3D geospatial datasets such as photogrammetry, CAD, and 3D building models.Specification
The open standard 3D runtime format for 3D models. Developed with the Khronos Group.Specification
Open Source Projects
To realize the full potential of 3D geospatial, we've also started and contributed to open source projects in the 3D ecosystem in addition to CesiumJS.
A web page that reports a browser's WebGL capabilities.
Tools for debugging, analyzing, and validating 3D Tiles tilesets that we developed with the University of Pennsylvania.
A C# and Java library for writing CZML content.
We cultivate a number of projects in support of glTF:
A tool to convert COLLADA files to glTF that we contributed to, originally started by Motorola Mobility.
A tool to convert OBJ assets to glTF that we developed.
Content pipeline tools for optimizing glTF assets that we developed with the University of Pennsylvania.
An extension for Visual Studio Code that adds features for previewing and editing glTF files that we developed that Microsoft contributes to.
A documentation tool to generate Markdown documentation from JSON Schema we developed that Microsoft contributes to.
We are active members of the larger open source, geospatial, and graphics communities of which Cesium is a part.
We write, edit, and review high quality content online and in print. Our blog is recognized as a go-to source of information about 3D geospatial. Our team has contributed to a number of books, including 3D Engine Design for Virtual Globes, WebGL Insights, and Real-Time Rendering, fourth edition.Blog
We mentor students from University of Pennsylvania, Google Summer of Code, and the European Space Agency Summer of Code in Space. These students have produced significant open source projects in the Cesium, 3D Tiles, WebGL, and glTF communities.Read more
We are sponsors of OpenStreetMap, the largest user-generated map in the world. Many Cesium developers use OSM imagery in their applications. We're happy to support the OSM community and contribute to the sustainability of this open dataset.Read more
Our team members have served on committees for open source conferences such as FOSS4G NA and FeoGeoDay, and we regularly sponsor, attend, and present on Cesium, 3D graphics, and building open source communities at many conferences and universities.Presentations
We encourage adoption of open source and open standards by curating projects and bringing developers together. We're invested in supporting formats and tools around Cesium, 3D Tiles, and glTF that serve the entire community.Our GitHub
