【摘要】 在对ＯｐｅｎＧＬ所采用的坐标系及各种变换作了详细地分析和论证的基础上，就建立航海模拟器视景显示过程中的模型视变换阵进行了推导，对ＯｐｅｎＧＬ采用的透视投影变换及透视投影变换阵作了细致地分析与推导，并由此对正确设置视见体参数提出了具体的建议．更多还原

【Abstract】 After a comprehensive analysis of model viewing transformation and other transformations. This paper deduces a model viewing matrix employed in generating 3D view of marine simulator, and also analyzes the perspective transformation and it’s transformation matrix employed by OpenGL graphics standard. Appropriate parameters used to define the viewing volume is also suggested.更多还原
