```
public class Layer3DOSGBFile
extends Layer3D
```
The 3D oblique photogrammetric cache (OSGB) layer class, inherited from the Layer3D class.
OSGB cache is a data storage format that has the advantages of larger data visibility, high loading efficiency, smooth level switching, and lower memory and CPU usage. Oblique photogrammetric model, BIM, pipeline, precision model data, vector buffer data can all be stored in this format.

- Field Detail
  - maxDataValue
```
public double maxDataValue
```
    Get the maximum height of the layer.
  - minDataValue
```
public double minDataValue
```
    Get the minimum height of the layer.
- Method Detail
  - getLODRangeScale
```
public double getLODRangeScale()
```
    Returns the distance zoom factor for switching the LOD level.
    OSGB cache controls the display of a certain level of LOD level within a certain distance range by setting the LOD switching distance. Assuming that the LOD switching distance is 200 meters, the model within 200 meters from the camera will display LOD level 0 (the finest level); the model with 200-400 meters will display the first level (sub-fine level), and so on.
    
    The LOD switching distance value cannot be changed directly after the OSGB cache is generated, but the LOD switching distance can be changed by changing the LOD level switching distance scaling factor, namely:
    
    New LOD switching distance = original LOD switching distance * LOD switching distance zoom factor
    
    Returns:
    
    The distance zoom factor for LOD level switching.
