A computer graphics system has a monitor, a database unit, an input section and an operational section. The database unit stores at least one set of lighting member information on a lighting member for controlling light incident on the object and optical characteristic information on optical characteristics of the lighting member. The input section inputs and instructs shape information, surface information and positional information of the object, light source information of a light source, viewpoint information, information on a kind of the lighting member, and positional information of the lighting member. The operational section generates image data of the object based on these information to be displayed as the two-dimensional image on a screen of the monitor. A computer graphics system displays a three-dimensional image of the object created in a virtual three-dimensional coordinate space on the screen as a two-dimensional image of the object.
