초록 ▼

An 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.

대표청구항 ▼

What is claimed is: 1. A method of three-dimensionally transforming two-dimensional flyover data in a three-dimensional graphics environment, comprising:(a) generating a division line list including one or more division lines for dividing a polygon constituting the two-dimensional flyover data into two regions;(b) selecting a division line for reducing a number of overlapped regions of the polygon among the division lines included in the division line list; and(c) separating the polygon into regions by applying the selected division line to the polygon, wherein the separated regions overlap each other at an overlapped region within the polygon,wherein each division line directly connects two vertexes among vertexes forming the polygon, each division line does not intersect a sideline of the polygon, and each division line exists within the polygon, andwherein the method is performed using at least one processor.
