| 摘 要： | 为使人们在观看水平面显示屏时保持舒适的姿势,设计1种使水平面显示屏虚拟斜置的方法. 根据斜置平面与水平面显示屏的投影关系,提出上置法和下置法两种实现方式,得出其相应的虚拟算法. 比较两种算法的优缺点表明,上置法对屏幕尺寸有一定要求,但可以保持视点处于固定的位置,下置法对屏幕尺寸无过高要求,但视点要移动. 最后通过具体实验证明两种算法的可行性和可靠性.

| Abstract: | To maintain a comfortable position for people who watches a horizontal screen, a virtual inclined plane algorithm of horizontal screen is proposed. According to the projection relationship between the inclined plane and the horizontal screen, the upper-placed method and the under-placed method are given and their virtual algorithms are deduced respectively. The comparison of the advantages and disadvantages between these two algorithms indicates: people can maintain a fixed position but the size of the screen must be big while using the upper-placed method; people have to change their position but the screen can be smaller while using the under-placed method. Finally, the two algorithms are proved to be feasible and reliable by specific experiment. |
