三维GIS纹理坐标数据管理方法的研究

Research About 3DGIS Texture Coordinates Data Management

纹理是建立真实感三维模型和场景至关重要的因素之一,越真实、越复杂的场景用到的纹理数据就越多,如何有效管理这些纹理数据和图像文件,避免冲突,节省显示内存,是三维城市景观需要解决一个难题。针对上述问题,本文就三维GIS纹理坐标数据管理提出了一个可行方案。

One of the important factors to establish realistic 3D model and the scene is the texture data. The more real and complex of the scenes ,the more the texture data should be used. It is a problem that how to manage the texture data and image files effectively,to avoid conflict, and to save display memory is what 3D urban landscape need to be solved. This article will put forward a feasible option on the 3DGIS texture coordinates data management responsed to these issues.
