Abstract
A shadow information storing method and apparatus is disclosed. The shadow information storing apparatus determines a shadow area through rendering a three-dimensional (3D) model based on light radiated from a reference virtual light source, determines a shadow feature value of a vertex of the 3D model based on a distance between a location of the vertex of the 3D model and the shadow area, and stores the determined shadow feature value.
