Play4D: Accelerated and Interactive Free-viewpoint Video Streaming for Virtual Reality and Light Field Displays # Play4D: Accelerated and Interactive Free-viewpoint Video Streaming for Virtual Reality and Light Field Displays ![](/sites/default/files/publications/output_6.gif) 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. ## Authors [Jonghyun Kim](/person/jonghyun-kim) [Michael Stengel](/person/michael-stengel) [Amrita Mazumdar](/person/amrita-mazumdar) [Tianye Li](/person/tianye-li) [Cheng Sun](/person/cheng-sun) [David Luebke](/person/david-luebke) [Shalini De Mello](/person/shalini-de-mello) ## Publication Date Monday, December 15, 2025 ## Published in [ACM SIGGRAPH Emerging Technologies 2025](https://sa2025.conference-schedule.org/presentation/?id=emt_131&sess=sess182) ## Research Area [Artificial Intelligence and Machine Learning ](/research-area/machine-learning-artificial-intelligence) [Computer Graphics](/research-area/computer-graphics) [Computer Vision](/research-area/computer-vision) [VR, AR and Display Technology](/research-area/virtual-augmented-reality) ## External Links [Project Page](https://research.nvidia.com/labs/amri/projects/play4d/) ## Uploaded Files [SIGGRAPH Asia Emerging Technologies Abstract](https://d1qx31qr3h6wln.cloudfront.net/publications/SIGGRAPH_ASIA_2025_E_Tech__2_page_%20%281%29.pdf "Open file in new window")721.69 KB ## Copyright Copyright by the Association for Computing Machinery, Inc.
