The basic principle of shooting 3D involves a “ right and left ” visual setup, which means two camera lenses to shoot images from different perspectives, simulating human vision. With special devices like glasses so the audience receives different signals for each eye, three-dimensional effects can be achieved.
由於 3D 拍攝的基本原理是「左右眼分治」，意即須以兩台攝影機模擬人的雙眼，以不同視角拍攝影像，並且在放映時搭配特殊裝置及眼鏡，同時「餵給」觀眾雙眼不同的訊號，才能達成立體效果。
