The extension enables portable, self-contained interactive behaviors embedded directly in glTF assets using a behavior graph system — interconnected nodes representing operations, events, control flow, and data transformations. This eliminates the need for platform-specific custom code to add interactivity to 3D assets. Use cases include triggering animations on proximity, showing/hiding content on user input, and procedural animations. The design is extensible, composable, and safe (preventing infinite loops), with graceful degradation when companion extensions are unavailable. Real-world support already exists in Babylon.js, Needle Engine (Unity exporter), Google Android XR via Jetpack XR SDK, Magic Leap, Amazon, and UX3D's glTF-Sample-Viewer. Khronos is soliciting feedback from developers and creators as ratification proceeds, with an in-person forum at SIGGRAPH 2026 on July 23. ## Full article daily.dev links to this article rather than hosting it.
