    • A technique for universally rasterizing graphic primitives used in computer graphics is described. Configurations of the technique include determining three edges and a bounded region in a retrofitting bounding box. Each primitive has real and intrinsic edges. The process uses no more than three real edges of any one graphic primitive. In the case of a line, a third edge is set coincident with one of its two real edges. The area between the two real edges is enclosed by opposing perimeter edges of the bounding box. In the case of a rectangle, only three real edges are used. The fourth edge corresponds to a bounding edge provided by the retrofitting bounding box. In exemplary applications, the technique may be used in mobile video-enabled devices, such as cellular phones, video game consoles, PDAs, laptop computers, video-enabled MP3 players, and the like.
    • 描述了用于计算机图形中使用的用于普遍光栅化图形原语的技术。 该技术的配置包括确定三个边缘和改进边界框中的有界区域。 每个原语具有真实和内在的边缘。 该过程使用任何一个图形图元的不超过三个实际边缘。 在线的情况下,第三边缘被设置成与其两个实际边缘中的一个一致。 两个实际边缘之间的区域由边界框的相对的周边边缘包围。 在矩形的情况下,仅使用三个实际边。 第四边缘对应于由改装边界框提供的边界边缘。 在示例性应用中,该技术可以用于移动视频使能设备,例如蜂窝电话,视频游戏机,PDA,膝上型计算机,支持视频的MP3播放器等。
