XR Fragments

Discover, reference, navigate and query 3D online content

After the hype of early (and proprietary) virtual reality technologies like Second Life cooled down, there is recently a renewed push towards the ā€œ3Dā€ web which uses virtual reality technologies (also marketed under new brand names like "Metaverse"). While many technological building blocks are meanwhile available, seamlessly surfing the 3D web however seems quite far away still for a simple reason ā€” browsers exit fullscreen/WebXR mode when switching web addresses, essentially removing the immersive experience when navigating. While such a limitation comes from obvious security considerations, it also pushes VR/AR-Headset owners into walled gardens for a more pleasant experience.

XR Fragments is developing a simple public protocol for networked 3D webrings to discover, reference, navigate and query 3D online content (read-only). This allows to enable immersive 3D navigation, liberate 3D content from being locked away inside games / walled gardens and to query objects inside a 3D asset files, without the need of serverside backends.
