An image processing apparatus and an image processing method are proposed for the high speed generation of a model, such as a plane picture in animation, for which an outline is drawn. In the image processing apparatus, for using computer graphics to generate a polygon model in three-dimensional coordinate space, a first model, for which the normal vectors of polygons are directed outward, and a second model, in which the first model is included and for which the normal vectors of polygons are directed inward, are synthesized as a single model. The direction of the normal vector of a polygon is employed in the hidden surface removal process to determine whether the polygon should be displayed. That is, when the normal vector of a polygon includes an element extended in the direction of the viewpoint, the pertinent polygon is displayed; but when the normal vector of a polygon does not include an element extended in the direction opposite to that of the viewpoint, the pertinent polygon is not displayed. As a result, the second model is expressed as an outline of the first model.
