    摘要： The present application provides a light-ray modulating element, an eyeglass and a 3D displaying system. The light-ray modulating element is applied to a 3D displaying system, the 3D displaying system includes a 3D displaying device, and the 3D displaying device includes a display panel, and a lens unit disposed at a light exiting side of the display panel; light rays emitted by the display panel pass through the lens unit, are shot to the light-ray modulating element, and form two first viewpoint units at a light entering side of the light-ray modulating element, wherein each of the first viewpoint units includes at least two first viewpoints; and the light-ray modulating element is configured for converging light rays emitted by each of the first viewpoint units to form a second viewpoint unit.

    摘要： The aim of the invention is to form a 3D image using a lenticular structure comprising: a carrier layer comprising an arrangement of color sub-pixels and a lenticular array comprising convergent lenses facing the sub-pixels. A method of the invention comprises: performing visual inspection of the lenticular structure, during which sub-pixels viewable through the lenses are detected for a plurality of viewing directions; determining, based on the color of the sub-pixels detected for each viewing direction, grayscale levels required to reveal M images viewable through the lenticular array in the M viewing directions, respectively; and customizing the sub-pixel arrangement, during which the grayscale levels are engraved facing the sub-pixels in the carrier layer by focus of laser radiation through the lenses.

    摘要： Methods and apparatus for generating images to be displayed on lenticular displays. In these methods, a fixed mesh is generated offline, and in real-time texture information is mapped to the fixed mesh. In an offline process, texture and 3D mesh information for an object is used to render UV map views for multiple viewpoints of the object, view maps are generated from display calibration data, and a lenticular to UV map is generated from the UV map views and view maps. In real-time, texture information is captured, and a composite process is performed that generates a lenticular image for multiple viewpoints by sampling pixels from the texture based on the lenticular to UV map. The lenticular image is then displayed on the lenticular display. Detected positions of persons in the environment may be used to limit the number of viewpoints that are generated during the real-time composite process.
