Study on the Key Technique of the Hill Shading Virtual Roaming System Based on XNA

摘要：

　　It is helpful for people to understand the undulating topography with hill shading map. In this essay, we focus on how to shade the terrain blocks with XNA Game Studio3. 1 by using the global DEM data from geographic information public service platform set as the data source. Including LOD structure, constructing a Triangle Strip terrain block model, applying HSV color model to color vertices, using XNA default lighting model and adjust relevant parameters to generate shading effect. Finally, a global height-color mapping table designed was offered, the represented effects of prototype system were also showed.
