摘要： An index is assigned to each entry in the set of possible coverage masks and two functions are generated. One function translates an index to a coverage mask. Also, a sparse function generates an index from a coverage mask. These functions may be realized in hardware and are used during decompression and compression, respectively.

摘要： Methods and apparatus relating to techniques for provision of hierarchical Z-Culling (HiZ) optimization for texture-dependent discard operations are described. In an embodiment, a processor performs one or more operations (such as HiZ or Hierarchical Stencil test) on depth data of an image tile in response to a determination that texture space bounds of the image tile is fully opaque. The processor performs the one or more operations regardless of whether a discard operation is enabled. Other embodiments are also disclosed and claimed.

摘要： In some embodiments, a given frame or picture may have different shading rates. In one embodiment in some areas of the frame or picture the shading rate may be less than once per pixel and in other places it may be once per pixel. Examples where the shading rate may be reduced include areas where there is motion and camera defocus, areas of peripheral blur, and in general, any case where the visibility is reduced anyway. The shading rate may be changed in a region, such as a shading quad, by changing the size of the region.

摘要： A virtual reality apparatus and method are described. For example, one embodiment of an apparatus comprises: a compute cluster comprising global illumination circuitry and/or logic to perform global illumination operations on graphics data in response to execution of a virtual reality application and to responsively generate a stream of samples; a filtering/compression module to perform filtering and/or compression operations on the stream of samples to generate filtered/compressed samples; a network interface to communicatively couple the compute cluster to a network, the filtered/compressed samples to be streamed over the network; a render node to receive the filtered/compressed samples streamed over the network, the render node comprising: decompression circuitry/logic to decompress the filtered/compressed samples to generate decompressed samples; a sample buffer to store the decompressed samples; and sample insertion circuitry/logic to asynchronously insert samples into a light field rendered by a light field rendering circuit/logic.

摘要： In accordance with some embodiments, the knowledge that a capped frame time is used can be exploited to reduce power consumption. Generally a capped frame time is a pre-allocated amount of time to apply power for rendering in graphics processing. Generally the frame time involves the application of power and some down time in which only idle power is applied pending the next frame time. By making better use of that down time, power consumption reductions can be achieved in some embodiments.

摘要： An apparatus and method are described for a non-uniform rasterizer. For example, one embodiment of an apparatus comprises: a graphics processor to process graphics data and render images using the graphics data; and a non-uniform rasterizer within the graphics processor to determine different resolutions to be used for different regions of an image, the non-uniform rasterizer to receive a plurality of polygons to be rasterized and to responsively rasterize the polygons in accordance with the different resolutions.

摘要： A mechanism is described for facilitating environment-based lossy compression of data for efficient rendering of contents at computing devices. A method of embodiments, as described herein, includes collecting, in real time, sensory input data relating to characteristics of at least one of a user and a surrounding environment. The method may further include evaluating the sensory input data to mark one or more data portions of data relating to contents, where the one or more data portions are determined to be suitable for compression based on the sensory input data. The method may further include dynamically performing, in real time, the compression of the one or more data portions, where the compression triggers loss of one or more content portions of the contents corresponding to the one or more data portions of the data. The method may further include rendering the contents to be displayed missing the one or more content portions, where the missing of the one or more content portions from the contents is not apparent to the user viewing the contents via a display device.

摘要翻译： 在一些实施例中，给定的帧或图片可以具有不同的着色速率。 在一个实施例中，在帧或图像的某些区域中，阴影率可以小于每像素一次，而在其它位置，每个像素可以是一次。 可以减少阴影率的示例包括存在运动和照相机散焦的区域，外围模糊的区域，以及一般来说，任何可见度被降低的情况。 通过改变区域的大小，可以在诸如阴影四边形的区域中改变阴影率。
