摘要

通过使用类似UNIX™文本处理工具的工具构建方法，可以控制抗锯齿3d呈现系统的复杂性。这种方法需要一种简单的图像表示，所有渲染程序都可以产生抗锯齿，为这种表示提供合成算法，并使用命令语言将场景拼凑在一起。本文提倡一种将Porter和Duff的合成代数与z缓冲区相结合的表示，以提供简单的抗混叠3d合成。

Compositing 3-D rendered images

The complexity of anti-aliased 3-D rendering systems can be controlled by using a tool-building approach like that of the UNIX™ text-processing tools. Such an approach requires a simple picture representation amenable to anti-aliasing that all rendering programs can produce, a compositing algorithm for that representation and a command language to piece together scenes. This paper advocates a representation that combines Porter and Duff's compositing algebra with a Z-buffer to provide simple anti-aliased 3-D compositing.
