Summary:Aiming at the massive data organization and management of textures with various sizes for real-time rendering of large-scale 3D city models, this paper proposes a new method: a texture spatial index tree is built up based on the hierarchical spatial index of 3D geometries, and then the texture data is written into mapping files structure through depth-first and hierarchical iteration for the clustering of data blocks, which facilitates the flexible size-changed disk I/O operations. Experimental results prove such kind of storage is more compact and more effective than single file storage method, and enables the fast access of texture data.
