  • Publication number: 20210287418
    Abstract: A processor dynamically selects a render mode for each render pass of a frame based on the characteristics of the render pass. A software driver of the processor receives graphics operations from an application executing at the processor and converts the graphics operations into a command stream that is provided to the graphics pipeline. As the driver converts the graphics operations into the command stream, the driver analyzes each render pass of the frame to determine characteristics of the render passes, and selects a render mode for each render pass based on the characteristics of the render pass.

  • Publication number: 20210225060
    Abstract: A processing device and a method of tiled rendering of an image for display is provided. The processing device includes memory and a processor. The processor is configured to receive the image comprising one or more three dimensional (3D) objects, divide the image into tiles, execute coarse level tiling for the tiles of the image and execute fine level tiling for the tiles of the image. The processing device also includes same fixed function hardware used to execute the coarse level tiling and the fine level tiling. The processor is also configured to determine visibility information for a first one of the tiles. The visibility information is divided into draw call visibility information and triangle visibility information for each remaining tile of the image.

  • Publication number: 20210209831
    Abstract: A method, system, and non-transitory computer readable storage medium for rasterizing primitives are disclosed. The method, system, and non-transitory computer readable storage medium includes: generating a primitive batch from a sequence of one or more primitives, wherein the primitive batch includes primitives sorted into one or more row groups based on which row of a plurality of rows each primitive intersects; and processing each row group, the processing for each row group including: identifying one or more primitive column intercepts for each of the one or more primitives in the row group, wherein each combination of primitive column intercept and row identifies a bin; and rasterizing the one or more primitives that intersect the bin.

  • Patent number: 10957094
    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.

  • Patent number: 10943389
    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.

  • Patent number: 10546365
    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.

  • Publication number: 20190122417
    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.

  • Publication number: 20090033671
    Abstract: A method and device for enhanced rendering providing reduced memory bandwidth requirements in a graphics processor. In the rendering process, a classification buffer of limited bit length is used for classifying the pixels. Based on the classification, a decision on the pixel color may be made without accessing the multi-sample buffer for a portion of the pixels. This reduces the memory bandwidth requirements.
