A real-time elemental image array (EIA) generation method which does not sacrifice accuracy nor rely on high-performance hardware is developed, through raytracing and pre-stored voxel-pixel lookup table (LUT). Benefiting from both offline and online working flow, experiments will verified the effectiveness.
The elemental image array (EIA) for light field display, especially integral imaging light field display, was reliant on a virtual camera array, novel sampling algorithms, high-performance hardware or corresponding complex algorithms, which hinder its application. Without sacrificing accuracy and precision, we innovate a novel algorithm set to achieve video-level EIA generation. The invariable voxel to pixel relationship is pre-calculated and pre-stored as a lookup table or mapping. Benefiting from the very lookup table, the voxel array could be fast mapped to an EIA without contingent upon any high-end hardware.
