| 摘要: |
| 从自行设计的专用三维地形显示的硬件和软件系统的观点出发，讨论了高速三维地形显示系统的体系结构、关键技术及其实现方法。以新一代的高速处理器 INTEL i860 为核心，采用分配树技术，解决多路并行输出产生的竞争和瓶颈问题；实现Z-缓冲硬件算法，提高系统的图形消隐速度；设计多帧存体结构，支持多通道、多画面信息的快速显示。 |

| Abstract: |
| From viewpoint that the hardware and the software of special 3D terrain system must be designed by ourselves, we discuss the architecture，key techniques and their realization of a typical high speed 3D terrain system in this paper. First of all we select high speed processor INTEL i860 as kernel of the system. Then we design a special unit called' allocating tree' to solve the contention and bottleneck problem caused by mutil-tunnel outputs. Thirdly，we realize the hardware Z-buffer algorithm,by which visible surface determination can be sped. Lastly，we use mutil-frame buffer technique to support high refresh of mutil tunnels and mutil drawing bodies. |
