Gracia Streams 4D Volumetric Scenes at 75 Mbps to Quest 3, Cutting App Downloads
1 articles · Updated · UploadVR · May 19
Quest 3 users can now open Gracia’s WebXR site and stream fully volumetric mixed-reality captures in seconds, without installing an app or downloading multi-gigabyte scene files.
An order-of-magnitude compression gain made that possible: Gracia now sends keyframes plus motion-change deltas for Gaussian splats, while WebGPU in the browser handles rendering at near-native performance.
The service currently offers three streamable scenes, including a 4-minute musician performance with spatial audio; Apple Vision Pro support is in testing through a dedicated app because WebXR passthrough is restricted.
High-quality playback needs a steady 75 Mbps connection for 120K splats per frame, though Gracia has also demonstrated a lower-quality 17 Mbps mode at 15K splats per frame.
Capture remains expensive—about 60 synchronized cameras, studio costs of at least $15,000, and Gracia processing fees of $800 per minute—limiting how quickly volumetric streaming can scale.
As immersive streaming demands high-speed internet, will this technology create a new digital divide for XR users?
Could browser-based volumetric video finally make traditional 2D video obsolete in the age of spatial computing?
With streaming solved, has the hurdle for volumetric video just shifted from distribution to expensive content creation?
Gracia’s 75 Mbps 4D Volumetric Streaming: The New Standard for Photorealistic VR Content
Overview
Gracia has transformed virtual reality by enabling instant streaming of photorealistic 4D volumetric scenes directly to standalone VR headsets, removing the need for downloads or complex installations. This breakthrough delivers high-fidelity, lifelike content at consumer-friendly bandwidths, letting users experience digital performances as if they were present in their own rooms through advanced passthrough technology. Gracia’s engineering, especially in 4D Gaussian Splatting, overcomes previous technical barriers, making immersive experiences accessible and intuitive. While content creation remains complex, ongoing improvements aim to democratize volumetric media, opening new possibilities for industries like art, sports, and training, and paving the way for broader adoption.
