“…Examples of hybrid rendering on related effects include Macedo et al (2018) and Marrs et al (2018) which invoke ray tracing for reflections and antialiasing respectively only on pixels where rasterization techniques are unable to achieve realistic or desirable results. Beck et al (1981), Hertel et al (2009) and Lauterbach and Manocha (2009) employ the same strategy to produce accurate shadows.…”

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.

“…For realistic reflections, Macedo et al (2018) invokes ray tracing only on pixels with reflections that cannot be solved with just screen space information. In Marrs et al (2018), traditional temporal anti-aliasing (TAA) is also extended with ray-traced supersampling for regions with a high chance of TAA failure.…”

Motion blur is commonly used in game cinematics to achieve photorealism by modelling the behaviour of the camera shutter and simulating its effect associated with the relative motion of scene objects. A common real-time post-process approach is spatial sampling, where the directional blur of a moving object is rendered by integrating its colour based on velocity information within a single frame. However, such screen space approaches typically cannot produce accurate partial occlusion semi-transparencies. Our real-time hybrid rendering technique leverages hardware-accelerated ray tracing to correct post-process partial occlusion artifacts by advancing rays recursively into the scene to retrieve background information for motion-blurred regions, with reasonable additional performance cost for rendering game contents. We extend our previous work with details on the design, implementation, and future work of the technique as well as performance comparisons with post-processing. Background Information Hybrid RenderingRay tracing is a common approach to produce realistic effects like glossy reflections, depth of field, and a https://orcid.

The main purpose of this investigation is to use information from previous frames for partial synthesis of the new one. Algorithms utilizing already calculated information have become an integral part of many interactive applications in recent years, and using of such methods allows reduces the computational load on the GPU without significantly degrading the image quality. Despite its popularity, there are still serious unresolved issues that affect image quality in many scenarios. Especially acute are the issues of artifacts and frame distortions. This paper discuss ways of counting and using information from previous frames used in image rendering applications, and proposes a new algorithm which combine best traits of the previous ones.
