1. A navigation apparatus for guiding a vehicle along a driving route, comprising: a memory that stores 3D map data; and a controller that: sets a reference point on a route; sets a first point which is a first distance away from the reference point and a second point which is a second distance away from the reference point; sets a rectangular region along the route, the center line of the region passing through the first point and the second point, a side of the rectangular region closest to the first point being a predetermined distance beyond the first point in a travel direction of the vehicle; obtains 3D map data corresponding to the region; generates a 3D movie which has a predetermined viewpoint on the basis of the obtained 3D map data; and displays the generated 3D movie; wherein when the first point is set at an intersection, the controller sets a longer distance between the side of the region closest to the first point and the first point than a distance that would be set between the side of the region closest to the first point and the first point if the first point were not set at an intersection.
