Toward Practical Volumetric Video Streaming on Commodity Smartphones

Volumetric videos offer six degree-of-freedom (DoF) as well as 3D rendering, making them highly immersive, interactive, and expressive. In this paper, we design Nebula, a practical and resource-efficient volumetric video streaming system for commodity mobile devices. Our design leverages edge computing to reduce the computation burden on mobile clients. We also introduce various optimizations to lower the perceived "motion-to-photon" delay, to dynamically adapt to the fluctuating network bandwidth, and to reduce the system's resource consumption while maintaining a high QoE.
