    Support class used to build the composite representation of surface objects as a list of SurfaceTiles. We keep a reference to the tile builder instance used to build tiles because it acts as a cache key to the tiles and determines when the tiles must be updated. The tile builder does not retain any references the SurfaceObjects, so keeping a reference to it does not leak memory.

```
  - buildCompositeSurfaceObjects
```
protected void buildCompositeSurfaceObjects(DrawContext dc)
```
    Builds a composite representation for all SurfaceObject instances in the draw context's ordered surface renderable queue. While building the composite representation this invokes Renderable.render(gov.nasa.worldwind.render.DrawContext) in ordered rendering mode. This does nothing if the ordered surface renderable queue is empty, or if it does not contain any SurfaceObjects.
    This method is called during the preRender phase, and is therefore free to modify the framebuffer contents to create the composite representation.
    
    Parameters:
    
    dc - The drawing context containing the surface objects to build a composite representation for.
    
    See Also:
    
    DrawContext.getOrderedSurfaceRenderables()
  - checkGLErrors
```
protected void checkGLErrors(DrawContext dc)
```
    Called to check for openGL errors. This method includes a "round-trip" between the application and renderer, which is slow. Therefore, this method is excluded from the "normal" render pass. It is here as a matter of convenience to developers, and is not part of the API.
    
    Parameters:
    
    dc - the relevant DrawContext
  - clearFrame
```
protected void clearFrame(DrawContext dc)
```
  - createPickFrustum

```
  - draw
```
protected void draw(DrawContext dc)
```
  - drawCompositeSurfaceObjects
```
protected void drawCompositeSurfaceObjects(DrawContext dc)
```
    Causes the scene controller to draw the composite representation of all SurfaceObject instances in the draw context's ordered surface renderable queue.

public void setPickRectangle(Rectangle pickRect)
```
    Specifies the current pick rectangle in AWT screen coordinates, or null to indicate that there is no pick rectangle. Each frame, this scene controller determines which objects intersect the pick rectangle and places them in a PickedObjectList. This list can be accessed by calling SceneController.getObjectsInPickRectangle().
    If the pick rectangle is null, this scene controller ignores the pick rectangle and the list of objects returned by getObjectsInPickRectangle is empty.
    
    Specified by:
    
    setPickRectangle in interface SceneController
    
    Parameters:
    
    pickRect - the current pick rectangle, or null.
  - setScreenCreditController
```
public void setScreenCreditController(ScreenCreditController screenCreditController)
```
    Description copied from interface: SceneController
    
    Specifies the ScreenCreditController to use for displaying screen credits for the model of this screen controller.
    
    Specified by:
    
    setScreenCreditController in interface SceneController
    
    Parameters:
    
    screenCreditController - the screen credit controller. May be null, in which case screen credits are not displayed.
  - setVerticalExaggeration
```
public void setVerticalExaggeration(double verticalExaggeration)
```
    Description copied from interface: SceneController
    
    Specifies the exaggeration to apply to elevation values of terrain and other displayed items.
    
    Specified by:
    
    setVerticalExaggeration in interface SceneController
    
    Parameters:
    
    verticalExaggeration - the vertical exaggeration to apply.
  - setView
```
public void setView(View view)
```
    Description copied from interface: SceneController
    
    Sets the current view.
    
    Specified by:

    Parameters:
    
    view - the view.
