```
public WorldWindowImpl()
```
- Method Detail
  - shutdown
```
public void shutdown()
```
    Causes resources used by the WorldWindow to be freed. The WorldWindow cannot be used once this method is called. An OpenGL context for the window must be current.
    
    Specified by:
    
    shutdown in interface WorldWindow
  - getGpuResourceCache
```
public GpuResourceCache getGpuResourceCache()
```
    Description copied from interface: WorldWindow
    
    Returns the GPU Resource used by this WorldWindow. This method is for internal use only.
    Note: Applications do not need to interact with the GPU resource cache. It is self managed. Modifying it in any way will cause significant problems such as excessive memory usage or application crashes. The only reason to use the GPU resource cache is to request management of GPU resources within implementations of shapes or layers. And then access should be only through the draw context only.
    
    Specified by:
    
    getGpuResourceCache in interface WorldWindow
    
    Returns:
    
    The GPU Resource cache used by this WorldWindow.

```
  - createGpuResourceCache
```
public static GpuResourceCache createGpuResourceCache()
```
  - configureIdentityPixelScale
```
public static void configureIdentityPixelScale(com.jogamp.nativewindow.ScalableSurface surface)
```
    Configures JOGL's surface pixel scaling on the specified ScalableSurface to ensure backward compatibility with WorldWind applications developed prior to JOGL pixel scaling's introduction.This method is used by GLCanvas and GLJPanel to effectively disable JOGL's surface pixel scaling by requesting a 1:1 scale.
    Since v2.2.0, JOGL defaults to using high-dpi pixel scales where possible. This causes WorldWind screen elements such as placemarks, the compass, the world map, the view controls, and the scale bar (plus many more) to appear smaller than they are intended to on screen. The high-dpi default also has the effect of degrading WorldWind rendering performance.
    
    Parameters:
    
    surface - The surface to configure.
