    摘要: The present disclosure describes a new ray tracing shadowing method. The method is unique as it separates the shadowing from the tracing stages of primary and secondary rays. It provides high data locality, reduced amount of intersection tests, no traversals and no reconstruction of complex acceleration structures, as well as improved load balancing based on actual processing load.

    摘要: Aspects comprise shadowing method as part of ray tracing. It is based on uniform grid of cells, and on local stencils in cells. The acceleration structures are abandoned along with high traversal and construction costs of these structures. The amount of intersection tests is cut down. The stencils are generated in the preprocessing stage and utilized in runtime. The relevant part of scene data, critical for shadowing of all visible intersection points in a cell, is registered in the local stencil map, as a volumetric data. The runtime use of stencils allows a complete locality at each cell, enhanced utilization of processing resources and load balancing of parallel processing.

    摘要: The invention provides a system and method for determining memorability of one or more audio and/or visual content items. In the system of the invention, one or more presentation devices are used to present the audio and/or visual content items to one or more individuals. A monitoring apparatus monitors a level of neural stimulation in one or both of the precuneus and the superior temporal sulcus (STS) of an individual during exposure of the individual to the audio and/or visual content items, and generates data indicative of the level of stimulation of one or both of the precuneus and the STS in the individual. A CPU processes the data generated by the monitoring apparatus from one or more individuals to calculate one or more memorability scores of each of the one or more content items presented to the individual.
