1. An animation generating apparatus for generating a three-dimensional animation tracking a moving object, the apparatus comprising:
camera parameter setting means for setting a point of regard and a point of view based on a current position of the moving object using route data indicating a route of the moving object so that the point of regard is a position of the moving object located on the route, and the point of view is located on the route of the moving object in a first direction and at a fixed distance behind the point of regard; and
rendering means for generating an image directed from the point of view to the point of regard when the moving object changes direction by retrieving necessary rendering data from three-dimensional map data based on the point of regard and the point of view set by the camera parameter setting means,
wherein, when the direction of the moving object changes in a second direction perpendicular to the first direction, the point of view remains located on the route of the moving object traveling in the first direction at the fixed distance behind the point of regard and directed to the point of regard.
