I work at the intersection of business and product to advance 3D geospatial. I started Cesium & 3D Tiles, co-created glTF, taught hundreds of computer science and graphics students, and have contributed to over ten books on mapping, computer graphics, and games. Cesium is a tech company building the software platform for 3D geospatial visualization and analytics across industries from smart construction to defense to urban mapping. The Cesium ecosystem has thousands of software developers and millions of end users. We enable this community to build and use web-based 3D digital twins that fuse together massive real-world datasets including terrain, imagery, photogrammetry, point clouds, 3D cities, BIM & CAD interiors and exteriors, and vector data.
