About
Spatius renders 3D Gaussian splat avatars on the viewer's own device. Speech goes in, synchronised motion and audio come out over LiveKit, and the browser SDK draws the face and upper body in real time. Because the rendering happens client side, the cost per minute is a fraction of video-streamed avatars, and the avatar can be zoomed, framed and restyled without re-rendering anything on a server.
