We augment layered three-dimensional (3D) displays using a lens placed in front of or between attenuation layers. The lens, or similar optical element, improves the angular resolution of the system and enables translation of the displayed scene from a near-field image to a far-field projection. We analyze the relation between angular resolution (scene depth) and the number of layers and characterize the phase–space trade-offs between spatial and angular frequency components. We also introduce an algorithm for determining the layers of the display, which significantly reduces the computational requirements. The method is demonstrated on a standard 4D light field scene.
