Abstract: A simple technique for zmax-culling on a per-tile basis conservatively estimates the maximum depth of the samples in a tile using a layer of masks and a number of zmax-values. No feedback loop is needed from the depth unit, in some embodiments. In addition, the occlusion test may be masked.

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 translation: 可以通过剔除要被渲染的三角形不可见的透镜上的半空间区域来光栅化景深。 然后,内部测试仅对剩余的未被空白的半空间区域进行。 要渲染的三角形和正在处理的瓷砖之间的分离平面可用于定义半空间区域。

Abstract: A layered, filtered shadow mapping algorithm may be used for motion blurred shadows. The algorithm is divided into two passes, namely a shadow pass and a lighting pass. The shadow pass renders the scene using stochastic rasterization and generates a time-dependent shadow map augmented with per-sample motion vectors. The subsequent lighting pass renders the scene from the camera's point of view, and performs a shadow query for each sample seen from the camera.
Abstract translation: 分层的,过滤的阴影映射算法可用于运动模糊阴影。 该算法分为两个通道,即阴影通道和照明通道。 阴影通过使用随机光栅化渲染场景,并且生成以逐采样运动矢量增强的时间依赖的阴影图。 随后的照明通道从相机的角度呈现场景,并对从相机看到的每个样品执行阴影查询。

Abstract: In accordance with some embodiments, the knowledge that a capped frame time is used can be exploited to reduce power consumption. Generally a capped frame time is a pre-allocated amount of time to apply power for rendering in graphics processing. Generally the frame time involves the application of power and some down time in which only idle power is applied pending the next frame time. By making better use of that down time, power consumption reductions can be achieved in some embodiments.
Abstract translation: 根据一些实施例,可以利用使用加盖帧时间的知识来降低功耗。 通常,加盖帧时间是在图形处理中应用电力进行渲染的预分配时间量。 通常,帧时间涉及在下一帧时间内仅施加空闲功率的功率和一些停机时间。 通过更好地利用该停机时间,在一些实施例中可以实现功耗降低。
