Rayleigh-Sommerfeld theory of planar screen diffraction is extended to spherical cases, related diffraction formula and its far field approximant within the spherical coordinate system are produced. 本文采用标量衍射理论导出球面屏衍射的瑞利-索末菲公式及其远场近似。
This paper puts forward the method of locating the 3D model in the screen coordinate in the design of the visual system of a submarine voyage training simulator. 该文主要论述了在潜艇航行训练模拟器三维视景仿真中,把三维模型投影到屏幕坐标系当中的方法。
According to the thought of Roberts algorithm, the hidden lines are removed by changing the solid to three dimentional screen coordinate system. 利用扫描边表显示图形,按照Roberts算法关于单个物体消隐的思想,将物体变换到三维屏坐标系中实施消隐。
