潮波传播的三维动态显示

介绍了应用微机开发的潮波传播三维动态显示软件系统，该系统在三维显示中解决了光线处理，坐标变换，隐藏面消除等问题，在潮波传播的动态显示中，应用二次编码压缩实现了微机上进行动态图象压缩的尝试，该系统用于显示东中国海Ｍ２分潮波的动态传播，形象且生动地展示了在南黄海海底辐射沙洲区域旋转潮波与前进潮波相遇并出现移动性驻潮波的全过程。

3 D Display of Tidal Wave Propagation

This paper presents a 3 D display system realizing on micro computer tidal wave propagation. In the course of study, some problems, such as the light treatment, coordinate transformation, concealment elimination, etc., have been solved. During the development of the display system, a technique of twice coding was adopted in an attempt to compress moving pictures on micro computer. The system has been used to show the dynamic propagation of M 2 tidal wave in the East China Sea. The whole process including the combination of a rotating tidal wave and a progressive wave and the resulting moving standing wave in the region of the South Yellow Sea Radiate Shoal, can be demonstrated vividly on a micro computer screen.
