The Khronos Group today submitted the glTF 2.0 extension designed to embed portable, self-contained interactive behaviors directly into 3D assets.">KHR_interactivity extension for glTF 2.0 for ratification. This extension aims to enable creators to embed portable, self-contained interactive behaviors, expressed as behavior graphs, directly within the glTF asset itself. This capability eliminates the need to hard-code interactivity for each platform and application, streamlining the creation of interactive 3D content. According to Khronos, the extension is "the result of substantial collaboration across the 3D content ecosystem, with support already established in multiple tools and runtimes." This move is significant as interactive 3D content becomes increasingly central across various markets.
