Abstract
Provided is a method for generating light emission data for a three-dimensional display provided with a plurality of multicolor light emitting elements arranged in three-dimensional directions, the method comprising: a modeling step for acquiring a 3D polygon model; a voxelization step for representing the 3D polygon model by a plurality of voxels and calculating position information of each of the voxels; a surface color calculation step for calculating, for the 3D polygon model, color information of a front-side surface with respect to a specific point of view and color information of a back-side surface with respect to the specific point of view; an interior color calculation step for referring to the position information and calculating, on the basis of the color information of the front-side surface and the color information of the back-side surface, color information of voxels located between the front-side surface and the back-side surface; and a mapping step for referring to the position information and mapping the color information of each of the voxels to a two-dimensional relative position to generate the light emission data.
