摘要

A method of and an apparatus for producing an animation having a series of road drawings to be watched from a driver's seat of a vehicle during a travel between two predetermined positions in a road map. The road drawings are formed on the basis of road data indicative of roads and obtained through three-dimensional computer graphics. Road map data indicative of the road map are stored in a road map data base device (1) and includes node data indicative of nodes formed by intersections, corners and ends of the roads, link data indicative of links each connecting two of the nodes to define a road segment and road width data indicative of the widths of the road segments. The road map data covering a travel route between the predetermined positions are selected by a calculator (4) from the road map data base device (1). The road data are calculated by the calculator (4) on the basis of the selected road map data to produce the animation in such a manner that the roads are three-dimensionally shown in the road drawings.
