    Abstract: According to one embodiment, a given tile, made up of pixels or samples, may be of any shape, including a square shape. These pixels may contain colors, depths, stencil values, and other values. Each tile may be further augmented with a single bit, referred to herein as a render bit. In one embodiment, if the render bit is one, then everything is rendered as usual within the tile. However, if the render bit is zero, then nothing is rasterized to this tile and, correspondingly, depth tests, pixel shading, frame buffer accesses, and multi-sampled anti-aliasing (MSAA) resolves are not done for this tile. In other embodiments, some operations may be done nevertheless, but at least one operation is avoided based on the render bit. Of course, the render bits may be switched such that the bit zero indicates that everything should be rendered and the bit one indicates more limited rendering.

    Abstract: Depth of field may be rasterized by culling half-space regions on a lens from which a triangle to be rendered is not visible. Then, inside tests are only performed on the remaining unculled half-space regions. Separating planes between the triangle to be rendered and the tile being processed can be used to define the half-space regions.

    Abstract: Unlike a static primitive, where the depth function is planar, the depth function for a moving and defocused triangle is a rational function in time and the lens parameters. Compact depth functions can be used to design an efficient depth buffer compressor/decompressor, which significantly lowers total depth buffer bandwidth usage. In addition, this compressor/decompressor is substantially simpler in the number of operations needed to execute, which makes it more amenable for hardware implementation than previous methods.

    Abstract translation: 与静态原语不同，其中深度函数是平面的，移动和散焦三角形的深度函数是时间上的理性函数和透镜参数。 紧凑的深度功能可用于设计高效的深度缓冲压缩/解压缩器，显着降低了总深度缓冲带宽的使用。 此外，该压缩器/解压缩器在执行所需的操作数量上基本上更简单，这使得它比以前的方法更适合硬件实现。

    Abstract: Motion blur rasterization may involve executing a first test for each plane of a tile frustum. The first test is a frustum plane versus moving bounding box overlap test where planes bounding a moving primitive are overlap tested against a screen tile frustum. According to a second test executed after the first test, for primitive edges against tile corners, the second test is a tile corner versus moving edge overlap test. The corners of the screen space tile are tested against a moving triangle edge in two-dimensional homogeneous space.

    Abstract: We present a new culling test for rasterization of simultaneous depth of field and motion blur, which efficiently reduces the set of (x, y, u, v, t) samples that need to be coverage tested within a screen space tile. The test finds linear bounds in u, t space and v, t space respectively, using a separating line algorithm. This test is part of the foundation for an efficient 5D rasterizer that extracts coherence in both defocus and motion blur to minimize the number of visibility tests.
