Gracia debuts volumetric video streaming for Apple Vision Pro via 4DGS

This launch addresses the strategic content vacuum on Apple Vision Pro by transitioning from limited-perspective spatial video to true volumetric streaming. For the broader industry, Gracia’s 4DGS compression validates that photorealistic 3D human performances can be delivered over consumer broadband without multi-gigabyte downloads. By linking WebXR, game engines, and native visionOS apps, the move marks a pivot toward interoperable spatial content delivery that bypasses traditional hardware silos. Watch for whether Apple moves to integrate similar volumetric streaming protocols natively into visionOS 3.0 to compete with third-party codecs.

Gracia's path to the Apple Vision Pro began with a WebXR-first streaming debut in March 2026, when the company became the first to stream 4D Gaussian Splatting scenes directly in a browser with no app install required. That initial release ran on Meta Quest 3 via WebGPU rendering and offered three scenes, including a four-minute musical performance with spatial audio. The Vision Pro app, which launched on June 22, 2026, exists because Apple still does not permit WebXR pages to access camera passthrough, leaving browser-streamed captures floating in a black void rather than blended into the viewer's room.

The compression approach Gracia developed transmits keyframes plus motion-change deltas rather than the full Gaussian scene for every frame, a scheme the company says reduced bandwidth requirements by more than an order of magnitude compared with its earlier technology. High-quality streaming at roughly 120,000 splats per frame demands a constant 75 Mbps connection, while a lighter mode at approximately 17 Mbps drops to around 15,000 splats per frame. CTO and co-founder Andrey Volodin noted that rendering on the Vision Pro's dual 4K displays was among the most significant technical challenges the team faced.

Gracia has positioned itself as an end-to-end volumetric infrastructure provider rather than a capture studio. The app launched with more than 25 photorealistic scenes produced in partnership with volumetric studios worldwide, spanning entertainment, medical education, and training use cases. The company also ships plugins for Unity and Unreal Engine, and its stated ambition is to become the "YouTube of volumetric content." Capture economics remain a constraint: professional volumetric sessions typically require around 60 synchronized cameras and cost at least $15,000 per recording, with Gracia charging $800 per minute for processing.
