    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 ray-tracing information between the eye position and each lens unit of a multi-optical element module forms a region of visibility (RoV) that may cover a portion of the three-dimensional image in the three-dimensional space. When coordinating the physical characteristics of a display panel and the multi-optical element module, a plurality of elemental images can be obtained. 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.
