潜艇航行训练模拟器视景系统的设计与实现

提出了一种基于PC机的潜艇航行训练模拟器视景系统的设计方法，PC机采用符合PC／104标准的便携式计算机，该视景系统软件设计模块化，结构清晰，便于维护，使用DirectX SDK做开发工具，可以直接访问底层硬件，充分利用硬件的优化性能，同时又不失独立于硬件的特点，降低了系统对硬件的苛刻要求，在三维场景中，使用了纹理粘贴，雾化，纹理多级细化等技术，实现较好的仿真效果，在二维仪表仿真中，大量使用了透明粘贴技术，很好地模仿了指示灯亮，旋钮旋转等现象，该视景系统经过了系泊试验，表明该系统实时性好，图象质量高，较逼真的模拟了潜艇的操作环境，满足了艇员实际听任训练的需要。

DESIGN AND IMPLEMENTATION OF VISUAL SYSTEM IN SUBMARINE VOYAGE TRAINING SIMULATOR

Presents the design and implementation of a visual system for submarine voyage training simulator with modularized software to make the visual system structure perspicuous and its maintenance easy, and the DirectX SDK to enable the system not only to have direct to access the hardware to make use of their optimized performances,but also to be fully on their own to reduce the need for hardware, and the transparent blitting used in panel emulating to emulate the indicator light on and knob turning around, and concludes from test results that the visual system is real time and emulates the operating environments realistically, and it can achieve the goal of training with low cost hardware.
