Abstract
The present invention relates to a method and system for selectively blending buildings to improve route visibility in a 3D navigation system. A method for displaying a 3D map may include: detecting whether or not an object to be displayed on a map screen intersects with a route guiding line on the map screen with the object intersecting the route guiding line being blended therewith.
Claims17
A system for displaying a three-dimensional (3D) map, the system comprising:
- a memory having computer readable instructions stored thereon;
- and
- at least one processor configured to execute the computer readable instructions to:
- determine whether an object to be displayed on a map screen intersects a route guiding line;
- display the object and the route guiding line on the map screen, and blend the object intersecting the route guiding line, wherein the at least one processor is configured to operate on a plurality of virtual polygons based on vertices comprising a polyline corresponding to the route guiding line and a camera view point of the map screen, each of the plurality of virtual polygons being formed by connecting two adjacent vertices of the vertices and the camera view point;
- and
- detect the object intersecting the route guiding line by determining whether a polygon corresponding to the object and each of the virtual polygons intersect.
