| Abstract: | This paper introduces a method for generating 3D images using OpenGL, which has been rapidly adopted as the graphics API for real-time interactive 3D graphics applications since its first release in 1992 Then it presents the conception and one of generation algorithms of Delaunay triangulation, which is widely applied in GIS field as one of the most important DTM models On the basis of the Delaunay triangulation model, the paper gives the method for generating 3D relief maps using OpenGL with the Visual C as a developing tool |
