摘要： During compilation, the interval bounds for a programmable culling unit are calculated if possible. For each variable, interval bounds are calculated during the compilation, and the bounds together with other metadata are used to generate an optimized culling program. If not possible, then an assumption may be made and the assumption used to compile the code. If the assumption proves to be invalid, a new assumption could be made and the code may be recompiled in some embodiments.

摘要： 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.
摘要翻译：在一些实施例中，用于像素着色的架构能够灵活地控制着色速率和在镶嵌图元中的三角形之间的自动阴影重用。然后可以将像素着色的成本与几何复杂度分离。即使在非常有限的功率预算下，也可以更加可行地使用细分几何和细微几何。可以在参数补丁空间中的小局部网格上进行阴影处理，并对附近样本重新使用阴影。支持将着色器分解成多个部分，哪些部分以不同的频率进行着色。遮蔽率可以在本地和自适应控制下进行，以便将计算引导到视觉上重要的领域，并以优雅的质量下降来提供性能缩放。在一些实施例中，在贴片空间中的阴影的另一重要益处在于它允许有效地渲染分布效应，这进一步缩小了实时和离线渲染之间的差距。

摘要： 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.
摘要翻译：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。

摘要： In order to efficiently backface cull rendering primitives during computer graphics rendering, it is important to be sure that the rendering primitives to be culled are guaranteed to be backfacing even if the primitives are moving or are undergoing defocus blur. Therefore, we derive conservative tests that determine if a moving and defocused triangle is backfacing over an entire time interval and over the area of a lens. In addition, we present tests for the special cases of only motion blur and only depth of field.
摘要翻译：为了在计算机图形呈现期间有效地背面剔除渲染图元，重要的是要确保即使原图正在移动或正在进行散焦模糊，要剔除的渲染图元也会背面。因此，我们得出保守测试，确定移动和散焦三角形是否在整个时间间隔内和透镜区域上都背后。此外，我们还提供仅针对运动模糊和只有景深的特殊情况的测试。
