Abstract With the development of computer graphics, 3D Visualization technology has become more sophisticated, in all walks of life have made considerable progress. In the meantime, in order to alleviate Urban Wetland crisis and achieve sustainable development of urban ecosystem, through the establishment of wetland, protected areas and GIS database combined with the strengthening of the monitoring and management of Urban Wetlands propaganda. In this paper, 3D Visualization technology to the problem of Urban Wetlands which provide a new level of solutions.
Focus of this study are: OpenGL-based Urban Wetland scene visualization, 3D terrain modeling, 3D feature modeling and realistic to achieve environmental effects. The core part is to achieve OpenGL-based 3D scene, a brief description of immersive environment.
