Abstract: A hierarchical acceleration structure may be built for graphics processing using a 32 bit format. In one embodiment, the acceleration structure may be a k-d tree, but other acceleration structures may be used as well. 64 bit offsets are only used when 64 bit offsets are needed.

Abstract: A technique to promote load balancing in parallel graphics rendering. In one embodiment, one or more threads are associated with one or more rendering tiles and scheduled in a balanced manner on one or more graphics processing resources.

Abstract: Samples may be taken to determine illumination gradients across subdivided areas of a pixel to determine which pixels are more likely to experience aliasing. More samples are then taken in the regions that are more likely to experience aliasing. The determination of those regions that are more likely to experience aliasing may be completed automatically.

Abstract: A method and apparatus for binary classification includes using signs of float values to detect different subgroups, detecting whether all entries in the group belong to the same subgroup, splitting original subgroup into uniform subgroups and classifying subgroups using array of float values. Coherency in groups of rays is detected by generating a group of rays, determining an originating point and a direction for each ray in the group, determining coherency of the group of rays and determining a group of rays as coherent as one in which all rays determined to travel in the same direction for each coordinate x, y, and z and determining a group of rays as incoherent otherwise and traversing the group of incoherent rays differently from the coherent group of rays.

Abstract: Embodiments provide for ray tracing traversal that relies on selected geometrical properties of the application to reduce the number of operations required during each traversal step. The traversal algorithm does not depend on the number of rays in the group. As a result, multi-level traversal schemes may be implemented, starting with a large number of rays in a group and then reducing it as needed to maintain group coherency. Multi-level traversal schemes may be created by splitting large groups of rays while traversing acceleration structures.

Abstract: Embodiments of the invention provide for accelerated polygon intersection testing of rays against a set of polygons. The amount of computation required in the rendering process is reduced by preprocessing the scene into a data structure that can be more efficiently traversed. During the preprocessing stage, triangles such as triangle may be converted into vertex and edge representation.

Abstract: A given computer graphics scene may be rendered as a set of triangles. A set of photons may be distributed over the scene, and a number of steps may be performed for each triangle. For each triangle, a list of photons may be constructed. For that triangle, a set of control points may be identified for purposes of determining global illumination. For each control point, a specific illumination estimate may be computed. A kd-tree of the control points of the triangle may be built. An illumination estimate may then be drive for the triangle.

Abstract: For a processor-based device capable of network communications, a workload associated with a wireless link to a network may be partitioned into software and hardware implementable portions based on a link communication profile. In response to a different link communication profile, the workload may be re-configured to simultaneously support another wireless link protocol different than that of the configured wireless link.
