“…With the use of artificial neural networks, neural rendering [30] is showing great promise in generating high-fidelity graphics with less manual effort and shorter render times as compared to traditional rendering, motivating recent works on soft shadows [7,8,25] and ambient occlusion [13,17,19,37]. However, the execution of trained machine learning models on thin clients is generally too slow to meet the performance requirements of interactive applications.…”

Distributed hybrid rendering (DHR) is a real-time rendering approach that incorporates cloud-based ray tracing with locally rasterized graphics for interactive thin client metaverse and game applications. With cloud assistance, DHR can generate high-fidelity ray-traced graphics contents remotely and deliver them to thin clients with low graphics capability, including standalone extended reality devices and mobile phones, while maintaining interactive frame rates for users under adverse network conditions. DHR can already achieve the effect of ray-traced hard shadows that form with the occlusion of direct illumination. We enhance the realism of these shadows by softening their edges with the direction of rays traced and approximating the occlusion of indirect illumination by reconstructing ray-traced ambient occlusion with a modified version of spatiotemporal variance-guided filtering. Our technique uses only 20–30% of the bandwidth of remote rendering and is also tolerant of delays of up to 200 ms with only slight distortion to the shadows along object edges.
