A Hybrid System for Real-time Rendering of Depth of Field Effect in Games

Abstract

Real-time depth of field in game cinematics tends to approximate the semi-transparent silhouettes of out-offocus objects through post-processing techniques. We leverage ray tracing hardware acceleration and spatiotemporal reconstruction to improve the realism of such semi-transparent regions through hybrid rendering, while maintaining interactive frame rates for immersive gaming. This paper extends our previous work with a complete presentation of our technique and details on its design, implementation, and future work. Background InformationCurrent DoF implementations in game engines typically use the thin lens model (Potmesil and Chakravarty, 1982) to approximate the behaviour of cameras. The zone of focus is the part of the scene a https://orcid.
