More Information
Summary:The present invention provides a method for displaying a three-dimensional map, wherein the amount of calculation is reduced and processing speed is increased when the th ree-dimensional map is displayed on a display panel by converting map data with two-dime nsional coordinates into map data with three-dimensional coordinates by means of a perspe ctive projection method. In the method of the present invention, map data with three-dimensional coordinates of a certain area with respect to coordinates of a reference position are loaded, or map data with two-dimensional coordinates are loaded and then modeled into map data with three-dimensional coordinates. The map data with three-dimensional coordinates are converted into those in a coordinate system based on the view point. A plurality of objects in the map data are classified according to properties thereof. The classified objects are rendered on a plurality of layers. The plurality of layers with the respective objects rendered thereon are displayed on one display panel in an overlapped state.
