摘要： In accordance with some embodiments, multi-sampling may be used together with texture filtering and particularly texture filtering that generally uses rectangular grids of samples. This is accomplished by performing the texture filtering before doing the resolve, while conventionally the resolve is done and then the texture filtering is done. In addition, each sample is filtered as if it were the only sample.

摘要： Described herein are computer graphics technologies to facilitate effective and efficient memory handling for blocks of memory including texture maps. More particularly, one or more implementations described herein facilitates hierarchical lossless compression of memory with null data support for memory resources, including texture maps. More particularly still, one or more implementations described herein facilitates the use of meta-data for lossless compression and the support of null encodings for Tiled Resources. This technology also permits use of the fast-clear compression method, where meta-data specifies that the entire access should return some specified clear value.

摘要： A mechanism is described for facilitating increased precision in large mip-mapped stitched textures for graphics computing devices. A method of embodiments, as described herein, includes detecting a stitched texture associated with a first frame of contents associated with an application, and a first region of interest in the stitched texture, where the stitched texture includes a mip-mapped stitched texture associated with multiple mip-levels in a mip-chain. The method may further include defining, at a first mip-level, a tile offset at a position within the first region of interest, where the first mip-level corresponds to the first frame. The method may further include creating or modifying a view of the stitched texture to specify the tile offset, and rendering the stitched texture as a normal texture with a full sub-texel precision.

摘要： An apparatus and method are described for occlusion queries for accelerated rendering. For example, one embodiment of a method comprises: performing an occlusion query for a plurality of tiles of an image, the occlusion query to determine whether one or more of the tiles are occluded; generating a bit mask in response to the occlusion query, the bit mask comprising data indicating which of the tiles are occluded; and reading the bit mask when rendering the image to remove work associated with those tiles which are occluded.

摘要： Some embodiments allow data conversions and meta-data to be specified using the page tables. As a result, individual memory resources can use their own compression methods or other conversions, and meta-data need only be specified for memory resources as necessary. Hardware engines and application code can access the memory resources as if they are stored in memory in the post-conversion, uncompressed form.
摘要翻译：一些实施例允许使用页表指定数据转换和元数据。因此，单独的内存资源可以使用自己的压缩方法或其他转换，并且只需要根据需要为内存资源指定元数据。硬件引擎和应用程序代码可以访问内存资源，就好像它们以转换后的未压缩形式存储在内存中。

摘要： Described herein are technologies related to facilitate lossy compression for multi-sample color data of computer graphics that maximizes the apparent quality of pixels while avoiding a corresponding burden on a memory and processor bandwidth. The lossy compression includes the steps of: obtaining pixel data associated with a multi-sample pixel stored in a memory, wherein the pixel data includes fragment data including a sample-to-fragment map that indicates fragment coverage of the samples; reading the sample-to-fragment map; and determining one or more samples are invalid and thus not associated with any fragment.

摘要： Described herein are technologies related to facilitate high precision and resolution of a depth (Z) buffer storage during a process of rendering 3D scenes. More particularly, during an interpolation, encoding, and/or storing processes in a graphic pipeline for rendering the 3D scenes, a particular depth (Z) plane representation is configured to support an un-normalized depth and a floating point depth formats that may be used to store Z values to the Z buffer storage.
