Abstract: A method and apparatus for ray tracing may include a method, manufacture and apparatus for ray tracing that may include dividing a render target into a plurality of bins. Next, a visibility pass is performed using ray tracing to generate a visibility stream such that the visibility stream indicates, for each bin of the plurality of bins, which primitives are visible in the bin. Then, for at least one bin of the plurality of bins, each primitive in the bin that is indicated in the visibility stream as being visible in the bin is rendered.

Abstract: This disclosure describes techniques for supporting intra-frame timestamps in a graphics system that performs tile-based rendering. The techniques for supporting intra-frame timestamps may involve generating a timestamp value that is indicative of a point in time based on a plurality of per-bin timestamp values that are generated by a graphics processing unit (GPU) while performing tile-based rendering for a graphics frame. The timestamp value may be a function of at least two of the plurality of per-bin timestamp values. The timestamp value may be generated by a central processing unit (CPU), the GPU, another processor, or any combination thereof. By using per-bin timestamp values to generate timestamp values for intra-frame timestamp requests, intra-frame timestamps may be supported by a graphics system that performs tile-based rendering.

Abstract: Systems, methods, and apparatus for performing queries in a graphics processing system are disclosed. These systems, methods, and apparatus may be configured to read a running counter at the start of the query to determine a start value, wherein the running counter counts discrete graphical entities, read the running counter at the end of the query to determine an end value, and subtract the start value from the end value to determine a result.
