摘要： Cluster of acceleration engines to accelerate intersections. For example, one embodiment of an apparatus comprises: a set of graphics cores to execute a first set of instructions of a primary graphics thread; a scalar cluster comprising a plurality of scalar execution engines; and a communication fabric interconnecting the set of graphics cores and the scalar cluster; the set of graphics cores to offload execution of a second set of instructions associated with ray traversal and/or intersection operations to the scalar cluster; the scalar cluster comprising a plurality of local memories, each local memory associated with one of the scalar execution engines, wherein each local memory is to store a portion of a hierarchical acceleration data structure required by an associated scalar execution engine to execute one or more of the second set of instructions; the plurality of scalar execution engines to store results of the execution of the second set of instructions in a memory accessible by the set of graphics cores; wherein the set of graphics cores are to process the results within the primary graphics thread.

摘要： Apparatus and method for a hierarchical beam tracer. For example, one embodiment of an apparatus comprises: a beam generator to generate beam data associated with a beam projected into a graphics scene; a bounding volume hierarchy (BVH) generator to generate BVH data comprising a plurality of hierarchically arranged BVH nodes; a hierarchical beam-based traversal unit to determine whether the beam intersects a current BVH node and, if so, to responsively subdivide the beam into N child beams to test against the current BVH node and/or to traverse further down the BVH hierarchy to select a new BVH node, wherein the hierarchical beam-based traversal unit is to iteratively subdivide successive intersecting child beams and/or to continue to traverse down the BVH hierarchy until a leaf node is reached with which at least one final child beam is determined to intersect; the hierarchical beam-based traversal unit to generate a plurality of rays within the final child beam; and intersection hardware logic to perform intersection testing for any rays intersecting the leaf node, the intersection testing to determine intersections between the rays intersecting the leaf node and primitives bounded by the leaf node.

摘要： Apparatus and method for ray tracing acceleration using a grid primitive. For example, one embodiment of an apparatus comprises: a grid primitive generator to generate a grid primitive comprising a plurality of adjacent interconnected primitives; a bitmask generator to generate a bitmask associated with the grid primitive, the bitmask comprising a plurality of bitmask values, each mask value associated with a primitive of the grid primitive; a ray tracing engine comprising traversal and intersection hardware logic to perform traversal and intersection operations in which rays are traversed through a hierarchical acceleration data structure and intersections between the rays and one or more of the adjacent interconnected primitives identified, wherein the ray tracing engine is to read the bitmask to determine a first set of primitives from the grid primitive on which to perform the traversal and intersection operations and a second set of primitives from the grid primitive on which the traversal and intersection operations will not be performed.

摘要： Cloud-based real time rendering. For example, one embodiment of a system comprises: a first graphics processing node to perform a first set of graphics processing operations to render a graphics scene, the first set of graphics processing operations comprising ray-tracing independent operations; an interconnect or network interface coupling the first graphics processing node to a second graphics processing node; the second graphics processing node to receive an indication of a current view of a user of the first graphics processing node and to receive or construct a view-independent surface generated by view-independent ray traversal and intersection operations; the second graphics processing node to responsively perform a view-dependent translation of the view-independent surface based on the current view of the user to generate a view-dependent surface and to provide the view-dependent surface to the first graphics processing node; and the first graphics processing node to perform a second set of graphics processing operations to complete rendering of the graphics scene using the view-dependent surface.
