Web3D 2026 explores how immersive 3D environments delivered and shared through the Web are transforming the future of digital interaction, and how recent advances in AI capabilities, embodied intelligent systems, and multimodal human interfaces are expanding what is possible in XR.

We invite submissions across all sectors in which the 3D Web plays a transformative role, including education, healthcare, e-commerce, cultural heritage, digital tourism, entertainment, media, construction, robotics, urban computing, and emerging industrial metaverse applications. The goal is to foster cross-disciplinary dialogue that shapes the future of interactive Web technologies and the extended multiverse.
