All keynotes, panels, breakouts, and workshops from this year’s Cesium Developer Conference are now up on YouTube, free to watch.
Full list here: 2026 Cesium Developer Conference Session Recordings – Cesium
A few sessions I’d point at depending on what you’re working on:
If you’re doing AEC/digital twin work: Barcelona’s underground twin, Madrid’s city-scale twin, the Cornell building energy model, and the Port of Dover session on net-zero planning.
If you’re deep in CesiumJS itself: the 3D Tiles 2.0 / glTF 2.1 deep dive, the CesiumJS Sandcastle + AI session on the new Copilot workflow, and the deep dive on connecting to ion and streaming 3D Tiles.
If you’re working with Gaussian Splats: two sessions this year, one on construction site applications, one from the Bentley team on the ion pipeline for generating splats from oblique imagery.
If you’re into the aerospace/simulation side: the lunar camera digital twin talk from Embry-Riddle, and the tactical wearables session from WearTAK.
Drop a reply if you watch something and have questions, happy to loop in the speaker or the team who worked on it if I can.
