The floating-image display module updates the floating image according to the interaction instruction, and the flat display module correspondingly displays another 2D image.

Abstract: A method for rendering data of a three-dimensional image adapted to an eye position and a display system are provided. The method is used to render the three-dimensional image to be displayed in a three-dimensional space. In the method, a three-dimensional image data used to describe the three-dimensional image is obtained. The eye position of a user is detected.

The elemental images form an integral image that records the three-dimensional image data adapted to the eye position, and the integral image is used to reconstruct the three-dimensional image.
