GlobeView.CachePath Property
Gets or sets the path to a directory on disk where tile elevation and surface textures are cached.
Syntax
public System.String CachePath { get; set; }Property Value
Default: ""
The path to a directory on disk where tile elevation and surface textures are cached.
Remarks
The GlobeView has the ability to cache the tiles loaded from ElevationInput and SurfaceLayers, using a cache file on disk. The first time an area of the globe is visited, the loading times for the tiles will be slightly higher than normal since the tiles are also written to the cache. But if the same tiles need to be loaded again, perhaps after the application is restarted, loading times can be significantly shorter using the cache compared to reading the original data again.
To enable the cache, set this property to the path of the cache directory. The directory and any intermediate directories will be created the first time the view is loaded. This directory should not be used for anything else. If you have more than one globe view configurations, they should use separate cache directories.
The cache can store different versions of the surface textures depending on the state of the surface layers. If you for instance disable a layer, or change it's opacity, a new version of the surface texture will be stored, which will coexist with previous versions. But if you make other changes to the configuration, for example change the color of a visualizer, you will need to clear the entire cache to prevent it from using old, incorrect tiles. To do that you can just remove the cache file from disk when the application is not running, or call FlushDiskCache to do that from the application itself.
More than one GlobeView instance can use the same cache file, provided they use identical configurations. This means that you can clone your view and display the clone in a second window, or start two instances of your application loading the same configuration file.
The amount of disk space used by the cache is controlled by the CacheSize property.
The property can only be changed before the first time the view is updated. If you try to change the property after that, an exception will be thrown.
