摘要
描述了EH实时计算机图像生成系统的体系结构、算法和工作流程.硬件由主机、几何处理器和象素处理器组成.主机支持操作系统和实时控制应用程序.几何处理器由两只CPU流水工作.几何处理速度为每秒一百万个四边形.象素处理峰值速度为每秒2.6亿个象素.系统具有多通道、多视点功能,可控运动目标128个,可产生白天、黄昏、霞光、黑夜和云雾大气效应.
The architecture, algorithm and operation flow of the EH real-time computer image generation system are described. The hardware consists of a host, a geometry processor and a pixel processor. The host supports operation system and the real-time control application program. The geometry processor includes two CPUs. The geometry processing velocity is 1 million quadrilaterals per second. The pixel rendering peak value rate is 260 Mpixels per second. The EH CIG system has multi-channel, multi-view-point functions. 128 moving objects can be controlled. Daytime, night fall, sun glow, night and cloud fog atmospheric effect can be generated.
