Information processing apparatus, information processing method, and program

A computer-implemented information processing method for generating a three-dimensional map on a computer display, which is a three-dimensional image, on the basis of three-dimensional map data concerning the three-dimensional map, the computer-implemented information processing method comprising the steps of:

• acquiring a rendering area, which is a geographical range in which the three-dimensional map is generated with respect to a focal point;
• identifying the three-dimensional map data in the rendering area, among the three-dimensional map data including rendering object data that concerns at least one rendering object rendered in order to generate the three-dimensional map and that is hierarchized into multiple groups in accordance with characteristics of the 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;
• selecting a group on the basis of the 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
• rendering the plurality of 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.
