LIGHTING OF ACHROMATIC LIGHT IN GRAPHIC SYSTEM, METHOD OF GENERATING GRAPHIC IMAGE, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To improve effects in unreal and other imaging attained using an inexpensive graphic system.

SOLUTION: This graphic system including a graphic and voice processor including a 3D graphic pipeline and a voice digital signal processor. Comic picture-like lighting and other unreal effects can be created by generating parameters other than a color or opacity used for a subsequent change of a color or an opacity value using the lighting calculation of a conversion unit 300. In more concrete, the lighting calculation is used to generate texture coordinates used in a texture mapping operation in an embodiment. A lighting computation result performs selection between brush strokes for the comic picture-like lighting and other effects by the texture mapping operation.
