Abstract: Ray tracing systems and methods for generating a hierarchical acceleration structure for intersection testing. Nodes of the hierarchical acceleration structure are determined, each of the nodes representing a region in a scene, the nodes being linked to form the hierarchical acceleration structure. Data is stored representing the hierarchical acceleration structure. The stored data comprises 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. Also described are ray tracing systems and computer-implemented methods for performing intersection testing 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: Systems, apparatuses, and methods for implementing a discard engine in a graphics pipeline are disclosed. A system includes a graphics pipeline with a geometry engine launching shaders that generate attribute data for vertices of each primitive of a set of primitives. The attribute data is consumed by pixel shaders, with each pixel shader generating a deallocation message when the pixel shader no longer needs the attribute data. A discard engine gathers deallocations from multiple pixel shaders and determines when the attribute data is no longer needed. Once a block of attributes has been consumed by all potential pixel shader consumers, the discard engine deallocates the given block of attributes. The discard engine sends a discard command to the caches so that the attribute data can be invalidated and not written back to memory.

Abstract: During tracing of a primary ray in a 3-D space (e.g., a 3-D scene in graphics rendering), a ray is found to intersect a primitive (e.g., a triangle) located in the 3-D space. Secondary ray(s) may be generated for a variety of purposes. For example, occlusion rays may be generated to test occlusion of a point of intersection between the primary ray and primitive is illuminated by any of the light(s). An origin for each secondary ray can be modified from the intersection point based on characteristics of the primitive intersected. For example, an offset from the intersection point can be calculated using barycentric coordinates of the intersection point and interpolation of one or more parameters associated with vertices defining the primitive. These parameters may include a size of the primitive and differences between a geometric normal for the primitive and a respective additional vector supplied with each vertex.

Abstract: The present disclosure provides a gamut mapping method and a system. The method includes: obtaining a brightness value of each sampling point corresponding to image data of a transmission end on a basis of a three-dimensional mapping table; performing equal-brightness cutting on a three-dimensional gamut model of the transmission end and a three-dimensional gamut model of a display end separately on a basis of the brightness value of each sampling point to form a corresponding equal-brightness two-dimensional surface; and performing color mapping on a basis of the formed equal-brightness two-dimensional surface and outputting mapping data. Hence, during gamut mapping, brightness and tone are kept unchanged, precise matching of three-dimensional gamut mapping from a transmission gamut to a display gamut is realized, avoiding problems of image distortion or a display error or the like due to mapping mismatch between the transmission gamut and the display gamut.

Traversal circuitry may traverse multiple nodes of the data structure and determine whether a ray intersects a bounding region indicated by given a node of the data structure based on the node information. Disclosed techniques may provide substantial improvements to performance, data size, and power consumption.
