<p>To transform the display mode of the structures located before the route when making turns, a navigation apparatus is described. In the event that the driving route is curved and the vehicle need to be turned, this navigation apparatus allocates three points (91,50,92) on the route which is before turning, during turning, and after turning, and sets a triangle region (98) which is formed with these three points. Subsequently, navigation apparatus sets a predetermined translucent ratio to the structures located within the triangle region (98), out of the structures in three-dimensional map data. Therefore, the structures are shown translucently and the route which is blind zone due to the structures may be displayed.</p> |
