    • Apparatus and method for rendering 3D-graphics images. The apparatus includes a port for receiving commands from a graphics application, an output for sending a rendered image to a display and a fragment-operations pipeline, coupled to the port and to the output, the pipeline (2MO) including a stage for performing a fragment operation on a per-pixel basis and on a per-sample basis. Performing on a per-pixel basis one of the following test stages: scissor, stipple (2BO), alpha (2CO) or color (2DO). Performing on a per-sample basis one of the following test stages: Z (2EO), blending (2FO) or dithering (2GO). The apparatus programmatically selects the following: whether to perform a stencil test (2EO) on a per-pixel or a per-sample basis and performs the stencil test (2EO) on the selected basis, pixel samples for per-sample operations, where the samples differ with different instances of the same per-sample operation, a set of subdivisions of a pixel as samples for use in the per-sample fragment operation, programmatically assigns different weights to at least two samples, and performs the per-sample operation using the programmatically selected and differently weighted samples.
    • 用于渲染3D图形图像的装置和方法。 该装置包括用于从图形应用程序接收命令的端口,用于将呈现的图像发送到显示器的输出和耦合到端口和输出的分段操作流水线,流水线(2MO)包括用于执行 在每个像素的基础上和每个样本的基础上进行片段操作。 在每个像素的基础上执行以下测试阶段之一:剪刀,点状(2BO),α(2CO)或颜色(2DO)。 在每个样本的基础上执行以下测试阶段之一:Z(2EO),混合(2FO)或抖动(2GO)。 该设备以编程方式选择以下内容:是在每个像素或每个采样的基础上执行模板测试(2EO),并在所选的基础上执行模板测试(2EO),每个采样操作的像素样本,其中 样本与每个样本操作相同的不同实例不同,作为在每个样本片段操作中使用的样本的像素的一组细分,以编程方式将不同的权重分配给至少两个样本,并且使用 以编程方式选择和加权不同的样本。
