Abstract

A three-dimensional information display apparatus which has three-dimensional map information processing section adapted to process three-dimensional map information, three-dimensional route information processing section adapted to process three-dimensional route information, and three-dimensional information display section adapted to display the three-dimensional map information processed by the three-dimensional map information processing section and the three-dimensional route information processed by the three-dimensional route information processing section. If a road to the destination included in the three-dimensional map information contains a downward branch part, the three-dimensional route information processing section processes the three-dimensional route information so as to extend a part of a route to the road to be branched for display while maintaining the same height as the height on drawing of the route to the destination at the downward branch part.

Claims

1. A three-dimensional information display apparatus comprising:

a three-dimensional route information processing section adapted to process three-dimensional route information indicating a route to the destination; and

a three-dimensional information display section adapted to display the three-dimensional map information processed by the three-dimensional map information processing section and the three-dimensional route information processed by the three-dimensional route information processing section,

wherein when the road to the destination included in the three-dimensional map information contains a downward branch part, the three-dimensional route information processing section processes the three-dimensional route information so as to display a part of the route extended to a road to be branched while maintaining the same height as the height on drawing of the route at the downward branch part.

2. A three-dimensional information display apparatus comprising:

a three-dimensional map information processing section adapted to process three-dimensional map information including a information of a road to a destination;

a three-dimensional route information processing section adapted to process three-dimensional route information indicating a route to the destination; and

a three-dimensional information display section adapted to display the three-dimensional map information processed by the three-dimensional map information processing section and the three-dimensional route information processed by the three-dimensional route information processing section,

wherein when a branching road branching from the road to the destination included in the three-dimensional map information contains an uphill road part, the three-dimensional map information processing section processes the three-dimensional map information so as to display a road portion higher than the viewpoint on drawing containing the uphill road part in a translucent manner.

3. A three-dimensional information display apparatus comprising:

a three-dimensional map information processing section adapted to process three-dimensional map information including a information of a road to a destination;

a three-dimensional route information processing section adapted to process three-dimensional route information indicating a route to the destination; and
