Play4D: Accelerated and Interactive Free-viewpoint Video Streaming for Virtual Reality and Light Field Displays
We present Play4D, an accelerated and interactive free-viewpoint video (FVV) streaming pipeline for next-generation light field (LF) and virtual reality (VR) displays. Play4D integrates 4D Gaussian Splatting (4DGS) reconstruction, compression and streaming with an efficient radiance field rendering algorithm to enable live 6-DoF user interaction with photorealistic dynamic scenes. Our demo showcases two complementary experiences: Play4D-LF, a walk-up station offering interactive multi-view playback on a LF display; and Play4D-VR, a headset-based experience that enables full volumetric navigation through 4DGS content.
