  - getViewer
```
public GLViewer getViewer()
```
    Returns a reference to the viewer which is handling this drawTool. Used mainly to determine the size and alignment of constrained motions. Should not be modified in any way.
  - updateBounds
```
public void updateBounds(Vector3d pmin,
                         Vector3d pmax)
```
    Description copied from interface: IsRenderable
    
    Update the minimum and maximum points for this object. In an x-y-z coordinate system with x directed to the right and y directed upwards, the minimum and maximum points can be thought of as defining the left-lower-far and right-upper-near corners of a bounding cube. This method should only reduce the elements of the minimum point and increase the elements of the maximum point, since it may be used as part of an iteration to determine the bounding cube for several different objects.
    
    Parameters:
    
    pmin - minimum point
    
    pmax - maximum point
  - isSelectable
```
public boolean isSelectable()
```
    Returns true if this object is in fact selectable.
    
    Returns:
    
    true if this object is selectable
  - numSelectionQueriesNeeded
```
public int numSelectionQueriesNeeded()
```
    If this selectable manages its own selection (by issuing selection queries within its render method), then this method should return the maximum number of selection queries that will be required. Otherwise, this method should return -1.
    
    Returns:
    
    maximum number of selection queries needed by this component, or -1 if this component does not manage its own selection.
  - getSelection
```
public void getSelection(java.util.LinkedList<java.lang.Object> list,
                         int qid)
```
    Append to list the component (or components) associated with the qid-th selection query issued by this component's render method. This will only be called if this component manages its own selection (i.e., the number nums returned by IsSelectable.numSelectionQueriesNeeded() is positive), and qid will in turn be a number between 0 and nums-1.
    
    Parameters:
    
    list - selected objects are appended to the end of this list
    
    qid - index of the selection query
  - prerender
```
public void prerender(RenderList list)
```
    Called prior to rendering to allow this object to update the internal state required for rendering (such as by caching rendering coordinates). The object may add internal objects to the list of objects being rendered, by calling
    list.addIfVisible (obj);
    for each of the objects in question.
    
    Parameters:
    
    list - list of objects to be rendered
  - getRenderHints
```
public int getRenderHints()
```
    Returns a bit code giving rendering hints about this renderable. Current bit codes include TRANSPARENT and TWO_DIMENSIONAL.
    
    Returns:
    
    bit code of rendering hints.
