Abstract:
1. An information processing apparatus generating a three-dimensional map, which is a three-dimensional image, on the basis of three-dimensional map data concerning the three-dimensional map, the information processing apparatus comprising: rendering area acquiring means for acquiring a rendering area, which is a geographical range in which the three-dimensional map is generated with respect to a focal point; identifying means for identifying the three-dimensional map data in the rendering area, among the three-dimensional map data including rendering object data that concerns a plurality of rendering objects rendered in order to generate the three-dimensional map and that is hierarchized into multiple groups in accordance with characteristics of the plurality of rendering objects with at least a first hierarchical group having a first set of characteristics of at least one rendering object and a second hierarchical group having a second set of characteristics of at least a different rendering object being less than the first set of characteristics of the at least one rendering object; rendering object data acquiring means for selecting a group on the basis of a distance from the focal point and acquiring the rendering object data in the selected group from the three-dimensional map data in the rendering area; and three-dimensional map generating means for rendering the rendering objects on the basis of the rendering object data acquired from the three-dimensional map data in the rendering area to generate the three-dimensional map.
