Title:
地図表示システム、地図データ加工装置、地図表示装置及び地図表示方法
Document Type and Number:
Japanese Patent JP4447865
Kind Code:
B2
Abstract:
A map data processing section categorizes original three-dimensional map data into scene graph data representing a data structure of a three-dimensional map using a tree structure and rendering data for rendering an object included in the three-dimensional map and processes the scene graph data and the rendering data. A map data display section specifies a display area by referring to the scene graph data and reads and displays the rendering data in accordance with the specified display area.
