  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.
