in addition, the coordinate system module uses the principle of similar triangle, the projection P' (Xs: Dxe/Ze, ys: Dye/Ze) of the point P on the screen, the screen is slightly different from the observation plane, the screen is a rectangular area on the observation plane, after a device-dependent transformation, the screen coordinates can be obtained from the observation plane coordinates, and the screen space is defined such that it only draws the scene enclosed in a closed space, which is called a frustum. The algorithm formula is as follows:

xe ± hze/D ye ± hze/D, (ze ═ D ze ═ F), where xe, ye, ze refer to the coordinates in the eye coordinate system, and plane ze ═ D and plane ze ═ F refer to the near and far clipping planes, respectively, which are perpendicular to the viewing direction, where we assume that the viewing plane coincides with the near clipping plane. For perspective projection, a so-called view cone is formed by connecting the window angle with the center of projection.
