摘要： While executing the standard graphics processing steps, problem polygons (i.e., those outside of a defined clip volume) are buffered for later processing, while the standard graphics processing continues, without the need for periodically reformatting data and performing clipping. After either a predefined number of polygons have been stored at the buffer location, or at such time as a change in the rendering state occurs, the buffered polygons are clipped.
摘要翻译：在执行标准图形处理步骤时，在标准图形处理继续进行的同时，不需要周期性重新格式化数据并进行裁剪，因此缓冲问题多边形（即，定义的剪辑卷之外的那些）被稍后处理。在预定义数量的多边形已经存储在缓冲器位置之后，或者在呈现状态改变的时候，缓冲的多边形被剪切。

摘要： In a multiprocessor system, such as a graphics data processing system, a method is disclosed for synchronizing the operations of two threads so as to execute a graphics data computation task with only one of the two threads. The method includes the steps of providing a set of local variables that are accessible, only through an atomic operation, by both of the threads. Before accessing a graphics data work buffer with one of the threads, testing a plurality of the local variables to ensure that the other thread has not already accessed the work buffer and, if it has not, setting one of the local variables to deny the other thread access to the work buffer. The method further includes the steps of accessing the work buffer and executing the graphics data computation task using the contents of the work buffer.
摘要翻译：在诸如图形数据处理系统的多处理器系统中，公开了一种用于同步两个线程的操作以便仅使用两个线程中的一个执行图形数据计算任务的方法。该方法包括以下步骤：通过两个线程提供只能通过原子操作访问的一组局部变量。在使用其中一个线程访问图形数据工作缓冲区之前，测试多个本地变量以确保另一个线程尚未访问工作缓冲区，如果没有，则将其中一个局部变量设置为拒绝其他线程线程访问工作缓冲区。该方法还包括以下步骤：使用工作缓冲器的内容访问工作缓冲区并执行图形数据计算任务。
