摘要
A method and apparatus for three-dimensionally transforming two-dimensional linear data in real time and a method and apparatus for three-dimensionally visualizing the two-dimensional linear data in real time. The method of three-dimensionally transforming two-dimensional linear data in real time includes: searching triangles in which vertexes constituting the two-dimensional linear data are contained among triangles constituting the three-dimensional topography data; calculating heights of the vertexes by using three-dimensional coordinates of the searched triangles; calculating intersection points between the triangles constituting the three-dimensional topography data and straight lines constituting the two-dimensional linear data; and calculating heights of the calculated intersection points. The two-dimensional linear data is three-dimensionally transformed in accordance with three-dimensional topography data in real time and three-dimensionally visualized together with three-dimensional topography data in real time, so that map information can be perceived intuitively and conveniently by a user.
