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: 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.
Abstract translation: 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。

Abstract: Two primitives may be merged by interpolating vertex attributes at coarse pixel centers. Input attributes are computed as a coverage weighted average of the interpolated vertex attributes. Then coarse pixel shading is performed using the merged primitives.

Abstract: An apparatus and method for performing coarse pixel shading (CPS). For example, one embodiment of a method comprises: A method for coarse pixel shading (CPS) comprising: pre-processing a graphics mesh by creating a tangent-plane parameterization of desired vertex attributes for each vertex of the mesh; and performing rasterization of the mesh in a rasterization stage of a graphics pipeline using the tangent-plane parameterization.

Abstract: A shading rate may be set by analyzing samples within a pixel. Then based on that analysis, a system determines whether to use coarse pixel, pixel or sample shading for a region of pixels. Based on the determined type of shading, the shading rate may be set.

Abstract translation: 用于散焦模糊的实时光场重建可用于处理同时散焦和运动模糊的情况。 通过仔细地引入几个近似值，导出非常有效的剪切重建滤波器，即使在一些实施例中对于非常低数量的输入样本也可产生高质量图像。 该算法可以在时间上是稳健的，并且比以前的工作快两个数量级，使得它在一些实施例中适合于实时渲染和用于高质量渲染的后处理通行。

Abstract: 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. An algorithm may be used to determine how the shading rate changes across the frame.
