Document Type and Number:
WIPO Patent Application WO/2022/042003
Kind Code:
A1
Abstract:
Provided are a three-dimensional coloring method and apparatus, which belong to the technical field of image rendering. The method comprises: acquiring position information and the intensity of at least one light source in a target space; according to the position information and the intensity of the at least one light source, determining at least one group of illumination information, under the irradiation of the at least one light source, corresponding to each surface of a three-dimensional object in the target space, wherein regarding any surface, the first group of illumination information corresponding to the surface comprises one or more layers of illumination information, and the one or more layers of illumination information reflect(s) illumination information, under the irradiation of a light source to which the first group of illumination information belongs, of each position point of the surface; and providing at least one group of illumination information for a device which performs coloring processing on the target space. By means of the present application, the amount of calculation of a coloring device can be reduced.
