ABSTRACT:
A method and computer program are provided for implementing a method for cartoonish picturization by generation from three-dimensional object data. The placement of the three-dimensional object, the view point, and the position of an illumination light source are set. The direction in which the three-dimensional object exists is obtained as mask information, the colors indicating the object are obtained as color information, the distance between the object outer surfaces and the view point is object as distance information, and normal vectors of the outer surfaces are obtained as normal vector information. Based on the mask information, the distance information, and the normal vector information, main lines (61, 71, 76) are plotted (23) as two-dimensional pixels, a based on the color information and a reference value, textures (601, 602, 701, 702) differing about the region of the reference value are applied to achieve visual gradation (24), and the main lines and textures are combined to generate a two-dimensional image that is a cartoonish picturization to be displayed.
