    Abstract: Methods and apparatus relating to techniques for provision of minimum or maximum and bitwise logic AND or logic OR based coarse stencil tests are described. In an embodiment, metadata (corresponding to a plurality of pixels) is stored in memory. One or more operations are performed on the metadata to generate a stencil result. 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: In accordance with some embodiments, a full per sample coverage mask may be used for a subset of the pixels in the tile, thereby enabling pixels that belong to multiple depth ranges to be handled. This makes the depth bounds a tighter fit for the true depth range of the tile and improves hierarchical depth culling efficiency when MSAA is used.

    Abstract: Real-time light field reconstruction for defocus blur may be used to handle the case of simultaneous defocus and motion blur. By carefully introducing a few approximations, a very efficient sheared reconstruction filter is derived, which produces high quality images even for a very low number of input samples in some embodiments. The algorithm may be temporally robust, and is about two orders of magnitude faster than previous work, making it suitable for both real-time rendering and as a post-processing pass for high quality rendering in some embodiments.

    Abstract: Because using the same number of bits per residual depth offset compression is not the best distribution of bits, the bits per residual may be distributed instead according to the content of the depths of a tile. For example, if the depth differences close to the Zmax are small, then fewer bits can be spent on residuals for the samples that are encoded relative to Zmax. Consequently, more bits can be spent on the residuals for the samples that are encoded relative to Zmin. As a result, more tiles succeed at compressing to the required number of bits.

    Abstract translation: 因为每个残留深度偏移压缩使用相同数量的比特不是比特的最佳分布，所以根据瓦片的深度的内容可以分配每个残差的比特。 例如，如果接近Zmax的深度差小，则相对于Zmax编码的样本的残差可以花费更少的位。 因此，对于相对于Zmin编码的样本的残差，可以花费更多的比特。 结果，更多的瓦片成功地压缩到所需的位数。

    Abstract: In accordance with some embodiments, a tile shader executes on a group of pixels prior to a pixel shader. The tile of pixels may be rectangular in some embodiments. The tile may be executed hierarchically, refining each tile into smaller subtiles until the pixel or sample level is reached. The tile shader program can be written to discard groups of pixels, thereby quickly removing areas of the bounding triangles that lie outside the shape being rasterized or quickly discarding groups of pixel shader executions that will not contribute to the final image.

    Abstract translation: 根据一些实施例，瓦片着色器在像素着色器之前的一组像素上执行。 在一些实施例中，像素块可以是矩形的。 可以分层执行瓦片，将每个瓦片细化为较小的子屏幕，直到达到像素或样品级别。 可以将瓦片着色器程序写入丢弃像素组，从而快速移除位于正被光栅化的形状之外的边界三角形的区域，或快速丢弃不会对最终图像做出贡献的像素着色器执行组。
