Taobao 3D Virtual Camp: Cloud Rendering and Real-Time Interaction Technology
Taobao’s 2022 Maker Festival unveiled a cloud‑rendered 3D virtual camp that supports thousands of simultaneous users without local downloads, using model simplification, texture optimization, dynamic scaling, frame synchronization, motion compensation, intelligent node selection and FEC to deliver 1080p real‑time interaction and low latency, with future plans to integrate XR/CG for larger‑scale experiences.
This article introduces the 3D virtual camp experience at Taobao's 2022 Maker Festival, showcasing the first online virtual interactive space supporting thousands of simultaneous users. The system leverages cloud rendering technology to deliver high-quality 3D graphics without requiring users to download large game engines or assets, solving the traditional mobile 3D application's storage and performance challenges.
Key technical highlights include cloud rendering cost optimization through model simplification, texture optimization, and dynamic scaling strategies; real-time interaction between 3D users and 3D products using frame synchronization and motion compensation algorithms; and achieving 1080p high-definition quality through UE4-based cloud rendering with dynamic camera switching and real-time user interaction response.
The system implements end-to-end ultra-low latency through intelligent node selection, bandwidth feedback, FEC, and dynamic buffering strategies, enabling smooth real-time interaction in the virtual world. Future plans include combining cloud rendering with XR/CG technology for customized virtual scenes supporting larger-scale real-time interactions.
