Abstract
In a method, a longitudinal angle, an azimuthal angle, illumination information, and color information of a pixel in a hair area of a virtual image corresponding to each optical path of a virtual main light source are obtained. For each optical path of the virtual main light source, a respective longitudinal scattering amount is determined based on the longitudinal angle and the illumination information of the pixel, a respective azimuthal scattering amount is determined based on the azimuthal angle of the pixel, and a respective scattering amount of the pixel corresponding to the respective optical path is determined according to the longitudinal scattering amount, the azimuthal scattering amount, and the color information of the pixel. Scattering amounts of the pixel corresponding to the optical paths of the virtual main light source are fused to obtain first coloring information of the pixel corresponding to the virtual main light source.
