Method, apparatus, and medium for three-dimensionally transforming two-dimensional flyover data in three-dimensional graphics environment and for three-dimensionally visualizing two-dimensional flyover data in three-dimensional graphics environment
A method, apparatus, and medium for three-dimensionally transforming two-dimensional flyover data in a three-dimensional graphics environment and a method, apparatus, and medium for three-dimensionally visualizing two-dimensional flyover data in a three-dimensional graphics environment are provided. The apparatus for three-dimensionally visualizing two-dimensional flyover data in a three-dimensional graphics environment includes an overlapped region separation unit, a triangulation unit, a height coordinate addition unit, and a visualization unit. The division lines are selectively applied to a polygon to separate overlapped regions from the polygon, an ear cutting algorithm is applied to triangulate the polygon, and various different visualization processes are performed on different portions of the flyover data, so that the two-dimensional flyover data can be effectively transformed into the three-dimensional flyover data and various appearance of the flyover can be visualized.
