Publication number: 20240029338Abstract: Disclosed approaches provide for irradiance caches which may be used to share irradiance between ray interactions spatially and/or temporally. An irradiance cache may store incoming irradiance or outgoing irradiance and may be updated by casting one or more rays from one or more locations to sample irradiance for the location(s). The number of rays that are cast may be reduced by ranking the locations, irradiance caches, and/or corresponding groups of geometry based on one or more characteristics thereof. For example, a ranking score may be computed based on camera distance, camera visibility, and/or a number of frames since a prior update. When sampling a location, outgoing irradiance from an outgoing irradiance cache may be used to determine shading when a hit distance of a ray used to generate the sample exceeds a threshold value.Type: ApplicationFiled: October 3, 2023Publication date: January 25, 2024Inventors: Oliver Mark Wright, Jakub Boksansky

Patent number: 11308684Abstract: In various examples, a virtual light meter may be implemented along with ray tracing techniques in order to determine incident light values—e.g., incoming irradiance, incident radiance, etc.—for adjusting auto exposure values of rendered frames. For example, one or more rays may be used to sample incident light over a sampling pattern—such as a hemispherical sampling pattern—for any position in a virtual game environment. As a result, the incident light values may be sampled near a subject of interest in a scene or frame such that exposure values are consistent or stable regardless of the composition of the rendered frames.Type: GrantFiled: August 17, 2020Date of Patent: April 19, 2022Assignee: NVIDIA CorporationInventors: Jakub Boksansky, Oliver Mark Wright

Patent number: 10054796Abstract: A display method is provided using a display that is operable to display an image to a viewer. The display method includes detecting one or both of an initial position and/or orientation of the viewer's head, and generating an image for display according to the detected position and/or orientation. A current position and/or orientation of the viewer's head are detected at a time at which the image is to be displayed. The method also includes re-projecting the generated image according to any differences between the initial position and/or orientation and the current position and/or orientation of the viewer's head, and displaying the re-projected image using the display.Type: GrantFiled: March 24, 2014Date of Patent: August 21, 2018Assignee: Sony Interactive Entertainment Europe LimitedInventors: Ian Henry Bickerstaff, Simon Mark Benson, Oliver Mark Wright, Sharwin Winesh Raghoebardajal
