Abstract: 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.

Abstract: Various embodiments provide for a new texture address mode that excludes any texture filter taps (i.e. coordinates) that fall outside the texture domain from the filtering process. Taps outside a texture domain are not considered in one embodiment. Also, various embodiments provide flexibility as to the texture coordinate locations ti and values of weights wi. The tap weight can be modified as a function of tap location and in particular whether a tap is within a texture.

Abstract: An architecture for pixel shading, enables flexible control of shading rates and automatic shading reuse between triangles in tessellated primitives in some embodiments. The cost of pixel shading may then be decoupled from the geometric complexity. Wider use of tessellation and fine geometry may be made more feasible, even at very limited power budgets. Shading may be done over small local grids in parametric patch space, with reusing of shading for nearby samples. The decomposition of shaders into multiple parts is supported, which parts are shaded at different frequencies. Shading rates can be locally and adaptively controlled, in order to direct the computations to visually important areas and to provide performance scaling with a graceful degradation of quality. Another important benefit, in some embodiments, of shading in patch space is that it allows efficient rendering of distribution effects, which further closes the gap between real-time and offline rendering.

Abstract: The adverse affects of using out-of-bounds texels for bilateral interpolation may be reduced by redefining the valid texel domain as having four corners defined at the centers of four corner texels. As a result, the texels around the periphery of the valid texture domain are partial texels, with the corner texels being one quarter of a texel and the edges being half of a texel.

Abstract: 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.

The one or more operations comprise a bitwise intersection operation or a bitwise union operation and/or a minimum operation or maximum operation. Other embodiments are also disclosed and claimed.

Abstract: 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 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.
