Abstract
A first surface, a second surface, and a third surface are set in order in a direction of a scene, and the first surface has a plurality of cells and a plurality of sub-cells divided from each of the plurality of cells, the second surface has a plurality of segments, and the plurality of cells and the plurality of segments are associated respectively. A trace direction of a ray passing through each sub-cell is determined based on a segment associated with a cell including the sub-cell. Ray tracing on the determined trace direction is performed for each sub-cell so as to generate light-field data of the scene between the second and third surfaces.
