This is not a video. Touch it.
Vortex is VoxaVerse's web viewer, running in this page right now. The scenes below are native 4D Gaussian reconstructions* — drag to orbit, scrub the timeline, or drop in your own splat file. More scenes coming soon.
* Current demo scenes come from the synthetic D-NeRF research dataset — compact captures with far less detail than a full multi-camera rig, so treat them as a taste, not a ceiling. Richer real-world scenes are being added — see the benchmarks page for full-fidelity reconstructions from a 21-camera rig.
What's native, what's supported, what isn't there yet
Every badge under the viewer is a live capability check from Vortex itself — never hardcoded on this page. .nx4d is VoxaVerse's own 4D delivery format: it's the only one that keeps time.
| Format | View | Export | Notes |
|---|---|---|---|
| .nx4d | Native (WebGPU, full 4D) | PLY at any scrubbed moment | VoxaVerse 4D stream — the only format that keeps time |
| .ply | Supported | PLY passthrough | Reference 3D Gaussian Splatting binary convention |
| .spz | Supported (v1–v3) | Re-exports to PLY | Niantic format; v4/ZSTD not yet supported in-browser |
| .sog | Supported | Re-exports to PLY | PlayCanvas format, bundled or unbundled |
| .gltf / .glb | Supported | Re-exports to PLY | Khronos KHR_gaussian_splatting extension |
How the 2D → immersive handoff works
The viewer renders inline in a 2D canvas on load — orbit, pan, zoom. The universal baseline that works everywhere WebGPU or WebGL2 runs.
Vortex checks WebXR session support for immersive-vr and immersive-ar independently. Buttons appear only for modes your device genuinely supports — never assumed.
The XR session starts inside your click on Enter VR/AR — required by the WebXR spec. A real session begins, rendered and sorted at interactive frame rates.
Ending the session restores the 2D view exactly where you left off — no reload, no lost state.
Honest on every device
Feature-detected at runtime, documented here in advance — you'll never hit a black screen or a faked button.
| Environment | What actually happens |
|---|---|
| Chrome/Edge desktop + Android | 2D everywhere; immersive VR and AR where the device supports them |
| Meta Quest Browser | 2D + immersive VR; passthrough AR depends on device/OS build |
| Apple Vision Pro (Safari) | Immersive VR only — visionOS Safari’s WebXR AR module is not yet functional, so no AR button is shown |
| iPhone / iPad Safari | No handheld WebXR in 2026. The 2D viewer always works; an AR Quick Look link appears only when a scene ships a real USDZ sibling — never faked |
| Firefox / non-WebXR browsers | 2D viewer only; XR buttons hidden entirely |

Nexus — the macOS studio built on the same engine that reconstructed everything you just saw — is coming soon. The benchmarks are already public.
