Abstract :
Based on the classification of the main urban landscape modeling objects, this paper establishes a 3D spatial data structure to achieve a series of topography and surface 3D reconstruction algorithms. And uses accelerated rendering algorithm and special effects to improve the 3D landscape rendering, uses 3D roaming engine to achieve the browse of web-based digital city 3D model.
