Abstract: A system, method and a computer program product are provided for hybrid rendering with deferred primitive batch binning. A primitive batch is generated from a sequence of primitives. Initial bin intercepts are identified for primitives in the primitive batch. A bin for processing is identified. The bin corresponds to a region of a screen space. Pixels of the primitives intercepting the identified bin are processed. Next bin intercepts are identified while the primitives intercepting the identified bin are processed.

Abstract: A method, computer system, and a non-transitory computer-readable storage medium for performing primitive batch binning are disclosed. The method, computer system, and non-transitory computer-readable storage medium include techniques for generating a primitive batch from a plurality of primitives, computing respective bin intercepts for each of the plurality of primitives in the primitive batch, and shading the primitive batch by iteratively processing each of the respective bin intercepts computed until all of the respective bin intercepts are processed.

Abstract: Systems, apparatuses, and methods for implementing light volume rendering techniques are disclosed. A processor is coupled to a memory. A processor renders the geometry of a scene into a geometry buffer. For a given light source in the scene, the processor initiates two shader pipeline passes to determine which pixels in the geometry buffer to light. On the first pass, the processor renders a front-side of a light volume corresponding to the light source. Any pixels of the geometry buffer which are in front of the front-side of the light volume are marked as pixels to be discarded. Then, during the second pass, only those pixels which were not marked to be discarded are sent to the pixel shader. This approach helps to reduce the overhead involved in applying a lighting effect to the scene by reducing the amount of work performed by the pixel shader.

Abstract: A system, method and a non-transitory computer readable storage medium are provided for hybrid rendering with deferred primitive batch binning. A primitive batch is generated from one or more primitives. A bin is identified for processing the primitive batch. At least a portion of each primitive intersecting the identified bin is processed and a next bin for processing the primitive batch is identified based on an intercept walk order. The processing is iteratively repeated for the one or more primitives in the primitive batch for successive bins until all primitives of the primitive batch are completely processed. Then, the one or more primitives in the primitive batch are further processed.

Abstract: An apparatus, such as a head mounted device (HMD), includes one or more processors configured to implement a graphics pipeline that renders pixels in window space with a nonuniform pixel spacing. The apparatus also includes a first distortion function that maps the non-uniformly spaced pixels in window space to uniformly spaced pixels in raster space. The apparatus further includes a scan converter configured to sample the pixels in window space through the first distortion function. The scan converter is configured to render display pixels used to generate an image for display to a user based on the uniformly spaced pixels in raster space. In some cases, the pixels in the window space are rendered such that a pixel density per subtended area is constant across the user's field of view.

Abstract: A processing system divides successive dispatches of work items into portions. The successive dispatches are separated from each other by barriers, each barrier indicating that the work items of the previous dispatch must complete execution before work items of a subsequent dispatch can begin execution. In some embodiments, the processing system interleaves execution of portions of a first dispatch with portions of subsequent dispatches that consume data produced by the first dispatch. The processing system thereby reduces the amount of data written to the local cache by a producer dispatch while preserving data locality for a subsequent consumer (or consumer/producer) dispatch and facilitating processing efficiency.

Abstract: Techniques for removing or identifying overlapping fragments in a fragment stream after z-culling are disclosed. The techniques include maintaining a first-in-first-out buffer that stores post-z-cull fragments. Each time a new fragment is received at the buffer, the screen position of the fragment is checked against all other fragments in the buffer. If the screen position of the fragment matches the screen position of a fragment in the buffer, then the fragment in the buffer is removed or marked as overlapping. If the screen position of the fragment does not match the screen position of any fragment in the buffer, then no modification is performed to fragments already in the buffer. In either case, he fragment is added to the buffer. The contents of the buffer are transmitted to the pixel shader for pixel shading at a later time.
