Discover, learn, and connect: the 2026 Cesium Developer Conference tracks are here
The Cesium Developer Conference 2026 returns for its second year, and the official conference tracks reflect an ambitious, innovative body of talks. Today, we’re excited to share them.
This year’s DevCon takes place June 8-10, 2026, at the Loews Hotel in Philadelphia.
Building on the momentum of our inaugural event, the conference will be a hub for developers, innovators, and creators from across the globe to connect, share ideas, and shape the future of open 3D geospatial technologies.
The 2026 Cesium Developer Conference will feature four technically oriented, community-driven tracks, offering a wealth of knowledge and insights for attendees.
Whether you're building immersive web apps, scaling digital twins, or pushing the boundaries of simulation, there’s a track for you.
Announcing the 2026 tracks
The conference will feature four themed tracks with nearly 50 20-minute full talks over both main days of the conference and a block of 16 5-minute lightning talks on June 9, highlighting openness and interoperability. Four tracks will run concurrently during the user sessions parts of the agenda.
We’ll release talk abstracts in early May to ensure you can tailor your DevCon experience.
Digital Twins and AEC innovation
Digital twin technologies are revolutionizing the architecture, engineering, and construction (AEC) industries. This track dives into how visualizing and analyzing projects in a geospatial context enhances collaboration, boosts efficiency, and reduces costs. Learn from real-world case studies, innovative workflows, and the integration of technologies like BIM, IoT, and simulation to create intelligent and operational digital twins.
If you’re working with design data, infrastructure at scale, or smart cities, this is your space.
Next-Gen Data and 3D Workflows
The future of geospatial is being built right now. This track focuses on the latest advancements in data capture, processing, and visualization. Discover new insights on AI and machine learning, advanced data streaming and visualization techniques, emerging technologies like WebXR, and emerging standards like 3D Tiles 2.0. Whether you are working with photogrammetry, LiDAR, or other 3D data sources, this track will provide valuable insights into the future of 3D. For attendees interested in performance, scalability, and what’s coming next, this is the track for you.
Aerospace, Defense, and Simulation
Open geospatial technology is a critical tool for analyzing our planet, monitoring global activities, and transforming orbital space. This track will feature developers who are leveraging 3D geospatial data and game engines to support users in the most demanding domains. Learn how these technologies are being used in mission planning, satellite operations, simulation and training, and the visualization of complex aerospace events. Get an inside look at planetary exploration, including missions to the Moon and Mars.
Cesium Core: Product Roadmaps & Advanced Technologies
The teams behind Cesium, iTwin, and 3D Tiles will share their latest work and roadmap. This track will provide a deep dive into the technologies that power the open geospatial ecosystem. Learn about the latest and upcoming product updates, enhancements in 3D Tiles and glTF, and new ways to leverage design data. Experts will explore the latest technologies, including Gaussian splats and AI-assisted development, that are enabling new applications and advancing the state of the art in 3D geospatial. For innovators who want to go deeper with Cesium and iTwin and influence what comes next, don’t miss these sessions.
