Research on the Software for Setting up Bi-viewpoint Autostereoscopic 3D Display Based on Direct 3D
基于Direct 3D的3维自由立体显示软件双视点设置

It is a crucial problem how to produce two pictures for left-eye and right-eye respectively with proper horizontal position disparity in autotereoscopic 3D display. The theoretic interrelation between the left-viewpoint and right-viewpoint in the model space by Direct 3D and the horizontal position disparity in the display screen has been established in this paper. The method for getting proper horizontal position disparity has been put forward aiming to provide proper sensation of depth as in real world and the most comfortable vision, and the theoretic formula is presented as well. Furthermore, two parameters, the position of left-viewpoint and fight-viewpoint in model world and the movement of the perspective plane, have been given in this paper, which directly affects the view result, The conclusions from this paper have gone into application and marvelous auto-stereoscopic 3D view has been achieved,
