Abstract: In a three-dimensional GIS, data volume is a critical issue particularly when we have to render the large amount data for visualizing a city in real time. For efficient analyzing and visualizing these data in real time, this study intend to develop a solution for fast visualizing large dataset three dimension (3D) model by a proposed view-dependent level-of-detail (LoD) model.
In this paper, we first propose a structure and corresponding algorithm to construct 3D data model of LoD for view-dependent rendering. Second, the algorithm is implemented within a prototype software Space/Info, which is developed by authors, and these are described in detail. Third, the performance and the newly proposed algorithm are tested via an experimental study in terms of roaming speed. Finally, the analysis and some conclusions are drawn
