  Classically, rasterization techniques are performed for real-time rendering
to meet the constraint of interactive frame rates. However, such techniques do
not produce realistic results as compared to ray tracing approaches. Hence,
hybrid rendering has emerged to improve the graphics fidelity of rasterization
with ray tracing in real-time. We explore the approach of distributed rendering
in incorporating real-time hybrid rendering into metaverse experiences for
immersive graphics. In standalone extended reality (XR) devices, such ray
tracing-enabled graphics is only feasible through pure cloud-based remote
rendering systems that rely on low-latency networks to transmit real-time
ray-traced data in response to interactive user input. Under high network
latency conditions, remote rendering might not be able to maintain interactive
frame rates for the client, adversely affecting the user experience. We adopt
hybrid rendering via a distributed rendering approach by integrating ray
tracing on powerful remote hardware with raster-based rendering on user access
devices. With this hybrid approach, our technique can help standalone XR
devices achieve ray tracing-incorporated graphics and maintain interactive
frame rates even under high-latency conditions.
