3D graphics programming employing 3D models provide an information-rich, interactive environment. Their use in CGI supported films, such as Avatar, demonstrate their ability to create a compelling audience experience. 3D models and 3D graphics programming have been available for many years. Graphics programming depends on knowledge of programming languages such as C++ and graphics libraries such as...
How to use the 3D (three-dimensional) modeling techniques better is the core problem in Digital City, which is also a harsh topic during the development of 3D GIS. Key problems in current 3D modeling techniques used in 3D GIS applications are discussed in this paper, and 2D and 3D interactively automatic construction technology of 3D model is presented. It constructs 3D model by extracting the region...
