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.
Based on the detailed analysis and demonstration of the coordinate system and various transformations used in OpenGL, this paper deduces the model visualization transformation matrix in the process of setting up the visual display of the navigation simulator, The perspective projection transformation matrix has been analyzed and deduced in detail, and concrete suggestions for setting the apparent body parameters are put forward accordingly.
