Cesium at I/ITSEC 2025

Enjoy drinks, appetizers, and great company during happy hour 3-5 p.m. Tuesday, December 2, at the Cesium booth.

OGC 3D Tiles and Well Formed Format

The One World Terrain Well Formed Format is an extension of 3D Tiles, enabling streaming of massive 3D datasets. We will be featuring sample data from One World Terrain, for which Cesium is proud to support the US Army and Vantor (formerly Maxar).

Cesium ion Self-Hosted

When Cesium users need to move their solution to the high side or a disconnected environment, Cesium ion Self-Hosted is the way to go. Cesium ion Self-Hosted provides an offline capability for hosting, tiling, and streaming massive heterogeneous 3D geospatial datasets. 

Reality modeling and analysis

Use Cesium ion to reconstruct 3D reality models from photos, such as high-res drone imagery, as 3D Tiles mesh and seamlessly stream them. Combine your reality data with Cesium World Terrain or other curated 3D data for a unified view and improved situational awareness. Run AI-powered reality analysis on point clouds for segmentation and embedded metadata.  

Save the date

Join us June 8-10 in Philadelphia for the 2026 Cesium Developer Conference. Watch the recorded sessions from 2025.

Join our team

Cesium is a team of passionate individuals working together to build the open platform for 3D geospatial through innovation, collaboration, customer focus, and continuous learning. Whether you’re an industry veteran or just starting out, you’ll get to work on interesting and challenging problems.

Cesium Certified Developer program

The Cesium Certified Developer program recognizes your technical expertise in building on the Cesium platform. The program is free and open to anyone. Becoming a Cesium Certified Developer enables you to connect and collaborate with the greater 3D geospatial ecosystem.

Open source for 3D geospatial

Cesium is deeply committed to openness and interoperability through open standards, open APIs, and open source offerings:

• CesiumJS—open source JavaScript library for creating world-class 3D globes and maps with the best possible performance, precision, visual quality, and ease of use for the web.
• Cesium for Unreal—combining the 3D geospatial capability of Cesium with the high-fidelity rendering power of Unreal Engine.
• Cesium for Unity—combining the 3D geospatial capability of Cesium and 3D Tiles with the Unity ecosystem.
• Cesium for Omniverse—enabling 3D geospatial capability for NVIDIA Omniverse, a real-time 3D graphics collaboration development platform, now supporting Isaac Sim.
• 3D Tiles for Godot—an open source plugin for Godot Engine built by Battle Road through the support of a Cesium Ecosystem Grant.

Partner demo: Virtuix Omni One VR treadmill

The Omni One VR treadmill by Virtuix delivers true freedom of movement in virtual environments—walk, run, crouch, and strafe in 360 degrees without leaving your spot. Paired with Cesium for Unreal, this system transforms training and mission rehearsal into fully interactive, geospatially accurate experiences.

Partner demo: Ansys Geospatial Data Cloud

Ansys Geospatial Data Cloud integrates Cesium ion Self-Hosted and global 3D content to provide Ansys STK with out-of-the-box access to accurate geospatial context within its time-dynamic simulations.

Partner demo: Battle Road AtomEngine and 3D Tiles for Godot

Battle Road is the developer of AtomEngine, a platform for simulation and modeling at planet scale, and has experience working with both Cesium and Godot technologies. 3D Tiles for Godot is an open source plugin for Godot Engine built by Battle Road through the support of a Cesium Ecosystem Grant.
