Abstract:
Spatial intelligence is set to reshape how we interact with and understand physical environments by enabling real-time immersive experiences. The ability to seamlessly digitize, stream, and render 3D spaces in real-time can transform industries such as entertainment, remote collaboration, healthcare, and supply chain sectors. However, achieving this vision requires overcoming significant technical challenges related to 3D data acquisition, processing, and transmission. In this talk, I will discuss the networking and systems challenges involved in capturing 3D spaces with high fidelity, focusing on live streaming and adaptive transmission strategies. Traditional 3D capture systems often face scalability, bandwidth efficiency, and latency limitations, which hinder their deployment in wide-area settings. I will introduce approaches such as MeshReduce and RenderFusion that address these challenges by leveraging distributed processing and adaptive streaming techniques. MeshReduce employs a decentralized architecture with hierarchical merging and adaptive bitrate control to efficiently process and transmit 3D content, reducing the computational burden on centralized servers and enabling scalable real-time 3D scene capture using edge devices. Complementing this, RenderFusion dynamically balances local and remote rendering to optimize user experience by intelligently selecting objects for rendering based on network conditions and device capabilities. This hybrid approach mitigates latency challenges while maintaining high frame rates and rendering fidelity, making it ideal for resource-constrained XR devices.
