Abstract: Ray tracing systems and computer-implemented methods are described for performing intersection testing on a bundle of rays with respect to a box. Silhouette edges of the box are identified from the perspective of the bundle of rays. For each of the identified silhouette edges, components of a vector providing a bound to the bundle of rays are obtained and it is determined whether the vector passes inside or outside of the silhouette edge. Results of determining, for each of the identified silhouette edges, whether the vector passes inside or outside of the silhouette edge, are used to determine an intersection testing result for the bundle of rays with respect to the box.

Abstract: Ray tracing systems and methods generate a hierarchical acceleration structure to be used for intersection testing in a ray tracing system. Nodes of the hierarchical acceleration structure are determined, each representing a region in a scene, and being linked to form the hierarchical acceleration structure. Data is stored representing the hierarchical acceleration structure, including data defining the regions represented by a plurality of the nodes. At least one node is an implicitly represented node, wherein data defining a region represented by an implicitly represented node is not explicitly included as part of the stored data but can be inferred from the stored data. Intersection testing in the ray tracing system is performed in which, based on conditions in the ray tracing system, a determination is made as to whether testing of one or more rays for intersection with a region represented by a particular node of a sub-tree is to be skipped.

Abstract: A system includes a vehicle and a vehicle control system configured to autonomously control one or more operations of the vehicle. The system also includes a navigation receiver configured to identify a location of the vehicle and to provide the identified location to the vehicle control system. To identify the location of the vehicle, the navigation receiver is configured to identify whether navigation signals received by the navigation receiver are spoofed based on angles of arrival for the navigation signals and to suppress any of the navigation signals determined to be spoofed. The navigation receiver may be configured to suppress any of the navigation signals determined to be spoofed in order to prevent an illicit actor from misdirecting the vehicle to an undesired location and/or to prevent an illicit actor from causing the vehicle to make course corrections based on an incorrect current location of the vehicle.
