NVIDIA’s latest AI model allows viewers to stream and view 3D scenes from any angle

The ability to stream immersive 3D video content from any viewing angle is becoming reality with NVIDIA’s latest breakthrough in artificial intelligence technology.

Core innovation: NVIDIA Research and the University of Maryland have developed QUEEN, an AI model that enables real-time streaming of free-viewpoint video, allowing viewers to experience 3D scenes from any angle.

• The technology balances compression rate, visual quality, encoding time, and rendering speed to create an optimized streaming pipeline
• Using NVIDIA Tensor Core GPUs, QUEEN can render free-viewpoint videos at approximately 350 frames per second with less than five seconds of training time
• The model efficiently handles dynamic scenes containing complex elements like sparks, flames, and furry animals

Technical approach: QUEEN’s efficiency stems from its intelligent handling of static and dynamic elements within video scenes.

• The system identifies unchanging elements between frames and reuses previous renders of static regions
• This approach allows more computational resources to focus on reconstructing dynamic content
• Previous methods struggled to balance memory requirements and visual quality, while QUEEN achieves both high quality and efficient streaming

Practical applications: The technology opens up new possibilities across multiple industries and use cases.

• Sports broadcasts could offer immersive virtual reality experiences and multi-angle instant replays
• Industrial settings could use QUEEN for more precise robotic teleoperation in warehouses and manufacturing plants
• Video conferencing could become more engaging with 3D demonstrations of tasks like cooking or origami
• Educational content could benefit from viewers choosing optimal viewing angles for learning

Implementation and availability: NVIDIA is making the technology accessible to the broader development community.

• The code will be released as open source and shared on the project page
• The research is being presented at NeurIPS, the premier conference for AI research
• This development is part of NVIDIA’s broader research initiatives, which include over 50 papers and posters at NeurIPS

Future implications: While QUEEN represents a significant advance in 3D video streaming, its true impact may be determined by how effectively it can be integrated into existing infrastructure and whether it can maintain its performance at scale across various real-world applications.
