this paper, and for the realization of a three-dimensional coordinates of the selected RIP (Ray-Intersecti on-penetration) method. Described how the window had been exaggerated to the three-dimensional scenes. use a mouse or related equipment selection of specific three-dimensional object methods. This method for the orthogonal projection or perspective projection is effective, relative to OpenGL to bring their own choices and feedback mechanisms, Whether this method is to select the algorithm accuracy or much higher efficiency is a more generic solution.
