Abstract

Virtual geographic environment is involved in many kinds of data, which are very huge. Many theories of 3D interactive visualization such as dynamic data loading are presented and applied to the navigation of the whole scene. However, in 3D modeling, some approaches such as segmentation of the whole scene into subareas are often adopted. Thus, the disaccord between visualization and modeling may cause trouble. In this paper, the integration of 3D interactive visualization and 3D modeling is discussed, and a collaborative 3D modeling environment is designed and constructed. As a case study, a virtual learning environment for Lushan fieldwork education is implemented.
