```
public class PointerBehaviorRenderer
extends MouseBehaviorRenderer
```
This behavior is supposed to "fly by pointer" - that is, zoom in, translate, and rotate to where the mouse is currently pointing. The velocity shall be constant, and the user will be able to control it though a slider.

```
public PointerBehaviorRenderer(JPanelView parent)
```
    Creates new pointer behavior, sets parent dialog, and resets MAX_ANGLE to the true start value.
    
    Parameters:
    
    parent - Parent dialog.
- Method Detail
  - integrateTransforms
```
protected void integrateTransforms()
```
    Creates a new transform for the image by multiplying the appropriate rotations and translations.
    
    Specified by:
    
    integrateTransforms in class MouseBehaviorRenderer
  - processMouseEvent
```
protected void processMouseEvent(java.awt.event.MouseEvent evt)
```
    Processes mouse event. For the left mouse button, changes translation; for the right mouse button, changes spin or pitch. If ALT key is down, zooms out.
    
    Specified by:
    
    processMouseEvent in class MouseBehaviorRenderer
    
    Parameters:
    
    evt - Mouse event to process.
