摘要： A method and system are disclosed for antialiased rendering a plurality of pixels in a computer system. The method and system comprise providing a fixed storage area and providing a plurality of sequential format levels for the plurality of pixels within the fixed storage area. The plurality of format levels represent pixels with varying degrees of complexity in subpixel geometry visible within the pixel. A system and method in accordance with the present invention provides at least the following format levels: one-fragment format, used when one surface fully covers a pixel; two-fragment format, used when two surfaces together cover a pixel; and multisample format, used when three or more surfaces cover a pixel. The method and system further comprise storing the plurality of pixels at a lowest appropriate format level within the fixed storage area, so that a minimum amount of data is transferred to and from the fixed storage area. The method and system further comprise procedures for converting pixels from one format level to take into account newly rendered pixel fragments. All formats represent depth values in a consistent manner so that fragments rendered during later rendering passes match depth values resulting from rendering the same primitive in earlier passes. Thus, the invention enables high-quality antialiasing with minimal data transferred to and from the fixed storage area, while supporting multi-pass rendering.
摘要翻译：公开了一种用于在计算机系统中抗锯齿渲染多个像素的方法和系统。所述方法和系统包括提供固定存储区域并为固定存储区域内的多个像素提供多个顺序格式级别。多个格式级别表示在像素内可见的子像素几何形状具有不同程度的复杂度的像素。根据本发明的系统和方法至少提供以下格式级别：当一个表面完全覆盖像素时使用的单片段格式; 两片段格式，当两个表面一起覆盖一个像素时使用; 和多重采样格式，当三个或更多个表面覆盖像素时使用。所述方法和系统还包括将所述多个像素存储在所述固定存储区域内的最低适当格式级别，使得最小量的数据被传送到所述固定存储区域和从所述固定存储区域传送。该方法和系统还包括用于从一个格式级别转换像素以考虑新渲染的像素片段的过程。所有格式都以一致的方式表示深度值，以便在后续渲染过程中渲染的片段匹配在较早的通过中渲染相同原语而产生的深度值。因此，本发明能够以最小的数据传输到固定存储区域和从固定存储区域传输高质量的抗锯齿，同时支持多遍渲染。

摘要： One embodiment of the present invention sets forth an architecture for advancing the Z-test operation prior to pixel shading whenever possible. The current rendering state, as maintained by the setup engine, determines whether advancing the Z-test function above the shader engine for “early” Z-testing is possible or whether the Z-test function should be deferred until after shading operations for “late” Z-testing. Data is dynamically routed to each processing engine in the pipeline, so that the appropriate data flow for either early Z or late Z is dynamically constructed, as determined by the current rendering state. The same functional units are utilized in both early Z and late Z configurations.
