Abstract: Apparatus and method for speculative execution of hit and intersection shaders on programmable ray tracing architectures. For example, one embodiment of an apparatus comprises: single-instruction multiple-data (SIMD) or single-instruction multiple-thread (SIMT) execution units (EUs) to execute shaders; and ray tracing circuitry to execute a ray traversal thread, the ray tracing engine comprising: traversal/intersection circuitry, responsive to the traversal thread, to traverse a ray through an acceleration data structure comprising a plurality of hierarchically arranged nodes and to intersect the ray with a primitive contained within at least one of the nodes; and shader deferral circuitry to defer and aggregate multiple shader invocations resulting from the traversal thread until a particular triggering event is detected, wherein the multiple shaders are to be dispatched on the EUs in a single shader batch upon detection of the triggering event.

Abstract: An apparatus and method for efficiently improving virtual/real interactions in augmented reality. For example, one embodiment of a method comprises: capturing a raw image including depth data; identifying one or more regions of interest based on a detected spatial proximity of one or more virtual objects and one or more real objects; generating a super-resolution map of the one or more regions of interest using machine-learning techniques or results thereof; detecting interactions between the virtual objects and the real objects using the super-resolution map; and performing one or more graphics processing or general purpose processing operations based on the detected interactions.

Abstract: An apparatus comprising a sorting unit to sort primitives of a graphics image, the primitives to be grouped, each group to form a first level node of a hierarchical acceleration structure; a parallel reconfigurable clustering array to construct the hierarchical acceleration structure, the parallel reconfigurable clustering array comprising a plurality of processing clusters, each cluster comprising: parallel efficiency analysis circuitry to evaluate different groupings of the first level nodes for a next level of the hierarchical acceleration structure to determine efficiency values for the different groupings; and node merge circuitry to merge the first level nodes based on the efficiency values to form second level nodes.
