[en] In this research, we propose a fast-computational light field image encoding method for a white light high-resolution full-parallax holographic 3D display and full-color rainbow holographic 3D display. With this method, a novel priority-based sequential rendering is used to improve the computation speed. The local visible 3D data is rendered at a higher priority and then used for rendering multiple local element light field images (EIs) at the holographic plane with the corresponding pinhole array behind the holographic plane. The EIs are independently coded as hogels by multiplying the corresponding phase function without using computation-intensive fast Fourier transform. This parallel computation method is implemented for both a full-parallax holographic 3D display and full-color rainbow holographic 3D display. An ultra high-resolution of a full-parallax hologram and a full-color rainbow hologram both at the resolution of 200 000 × 200 000 pixels only cost 14 min and 78 min, respectively. Our experimental results have also shown the effectiveness of the proposed high-resolution 3D display method. (paper)
