Show water with three-dimensional sense. This method does not produce a true three-dimensional image, but rather gives the viewer a different view of each eye to provide a three-dimensional effect, never making the scene with depth. To get a three-dimensional projection, you first need to get two views of the scene from the observation direction relative to each eye (left eye and right eye). You can obtain both views by specifying a different observation location and by a computer-generated scene, or by shooting some objects or scenes with a pair of stereoscopic cameras. When we get the left view and the right view at the same time with the left eye, the two views are composited into a single image and feel the scene with depth. One way to create a three-dimensional effect is to use a raster system to alternately display two views at different refresh intervals. With the eye observation screen, each lens is designed to be a high-speed, alternating shutter that synchronizes the display of another view. The stereoscopic view is also an integral part of the virtual reality (virtual-reality) system. Users can step into the scene and interact with the environment.
