ABSTRACT:
To render a three-dimensional object by using a plurality of dots, surfaces forming the three-dimensional object are divided into several regions based on curvature of the surfaces forming the object. A plurality of dots are arranged on the surfaces forming the object in accordance with rules which are different with respect to the different regions. To render a sphere by using a plurality of dots, spherical surfaces of the sphere are divided into polar regions and the equatorial region. In polar regions, dots whose number increase in accordance with radius around the axis of revolution are distributed at an equal interval on coaxial circumferences on polar regions. In the equatorial region, a certain number of dots are distributed at an equal interval on coaxial circumferences on the equatorial region so that a dot on the circumference are placed between dots on adjacent circumferences in the equatorial region.
