Digital Urban Three-Dimensional Technique Base on OpenGL

Abstract:

With the fast development of computer multimedia technology, space technology, visualization technology, digital geomatics technology and computer graphics technology, using three-dimensional GIS technology to realize virtual visualization scene become reality. Three-dimensional GIS had already been applied to a lot of fields, such as country resource management, urban planning, public security system, electric power telecom branch. The paper had paid great attention to the popular three-dimensional GIS technology which had been in progress studying nowadays. It has summarized the research content and developed condition of current three-dimensional GIS and expatiates on the comprehensive application foreground of three-dimensional GIS. It had discussed and studied the three-dimensional GIS modeling method and the key visualization technology which based on OpenGL. It designed and realized a three-dimensional GIS simulation system. The paper had done the main studies as follows: (1) 3D GIS modeling theory and method had been discussed in this paper, and the paper had realized 3D modeling based on 3dsmax become reality; (2) It had designed and realized a three-dimensional GIS simulation system based on visualization technology which based on OpenGL.
