Description
Use IGlobeAdvancedOptions interface to get\set Arcglobes advanced visualization and data management options. Using this interface you can get\set the following properties: CachePath where cache data will reside on the local machine, DefaultUse16ElevBits and DefaultUse16ColorBits default values for elevation and image color Compression, ClipNear and ClipFarFactor Near and Far Clipping planes that aid in performance optimization by clipping areas that do not fall within the applications view, LevelOfDetail the level of detail of image and elevation layers that gets applied during display, ManualLOD a boolean that indicates if manual LOD control is on and TargetFrameRate the target frame rate when using automatic control of LOD. Use VectorTileSize property to limit the amount of features (expressed as the maximum number of vertices) in a tile. Currently the maximum amount is 65,536 vertices (216) which is set as the default value. Lowering this value will in effect result in 'trimming' or dropping-off of features that exceed the limit set within a tile. This property applies to features treated as vectors only.
IGlobeAdvancedOptions interface also has methods GetUseCache and SetUseCache, to get\set whether disk cache will be used and the size to allocate for disk cache, a property to get if lossy compression is supported IsLossyCompressionSupported , and a method to get the default lossy compression option for a data type and its quality from 1 to 100 GetDefaultCompression.
The RestoreClipPlaneDefaults and RestoreLODDefaults methods set the default Clipping planes and level of Detail settings to their default values respectively. Most of these advanced options will not be used until WriteToRegistry is used to commit the changes to registry.

| GlobeAdvancedOptions | The globe advanced options object. |
The following code illustrates how to manipulate the advanced options available from this interface:
public void AdvancedOpts()
{
//pGlobe is a variable of type IGlobe
IGlobeDisplay pGlbDisplay = pGlobe.GlobeDisplay;
IGlobeAdvancedOptions pGlobeAdv = pGlbDisplay.AdvancedOptions;
//Get the current cache location
string currentCacheLocation;
currentCacheLocation = pGlobeAdv.CachePath;
bool pbLossyComp;
short pQuality;
//Pass the data type (esriGlobeDataType) as the first argument
pGlobeAdv.GetDefaultCompression(esriGlobeDataType.esriGlobeDataTexture,out pbLossyComp,out pQuality);
}
