Abstract:
1. An image generating method for rendering a three-dimensional object viewed from a predetermined viewpoint by generating an image of the three-dimensional object and writing color information on the image generated in a rendering buffer, the method comprising: operating a normal line to a surface of the three-dimensional object; setting a plurality of sampling points within a rendering region for the three-dimensional object, the rendering region on which the three-dimensional object is projected on the basis of the predetermined viewpoint; and rendering the three-dimensional object by performing processing for determining an arrangement angle of a predetermined brush image on the basis of the normal line operated at a position on the surface of the three-dimensional object, the position corresponding to each of the plurality of sampling points, and arranging the predetermined brush image at the arrangement angle determined at the position corresponding to each of the plurality of sampling points in the rendering buffer.
