Gracia
Infrastructure for dynamic 4D Gaussian-Splatting volumetric video, playable smoothly even on Quest and Pico VR headsets
What is it
Gracia is a UK startup focused on building full-stack infrastructure for dynamic 4D Gaussian Splatting volumetric video. "4D" adds a time dimension on top of 3D space — moving volumetric imagery; volumetric video lets viewers walk around in the space and view from different angles. Gracia's focus is letting this high-load content play smoothly on standalone VR headsets like Meta Quest and Pico.
What problem it solves
Volumetric video has long been the holy grail of immersive content, but with huge files and heavy computation, it could mostly only barely run on high-end equipment. Gracia builds a whole tech stack from capture and processing to playback, letting dynamic volumetric imagery render on compute-limited standalone headsets, pushing up the ceiling of immersive imagery. This is key for content makers wanting to make highly present performances, teaching, event records, or social experiences. It suits immersive-content studios and development teams investing in spatial computing. Note that as a startup and frontier tech, its maturity, tool-chain completeness, and real deployment cases are still developing.

Editor's Note
Aims at the hard bone of volumetric video, getting moving volumetric imagery to run on affordable headsets.
FAQ
How does 4D volumetric video differ from ordinary 3D?
4D adds time on top of a 3D space — moving volumetric imagery, and viewers can also walk around in the space to change viewpoint.
Which devices does it support?
The focus is letting standalone VR headsets like Meta Quest and Pico play this high-load content smoothly too.
Can it be used at scale for commercial projects now?
As a frontier startup, its tool chain and deployment cases are still developing, so it's advised to first evaluate fit with your own project.
