  - initTransform
```
public static void initTransform(ViewerPanel viewer)
```
    Set a "good" initial viewer transform. The viewer transform is chosen such that for the first source,
    - the XY plane is aligned with the screen plane,
    - the z = 0 slice is shown,
    - centered and scaled such that the full dim_x by dim_y is visible.
    This calls initTransform(int, int, boolean, ViewerState), using the size of the viewer's display component.
    Parameters:
    
    viewer - the viewer (containing at least one source) to have its transform set.
  - ensurePositiveZ

  - initTransform
```
public static AffineTransform3D initTransform(int viewerWidth,
                                              int viewerHeight,
                                              boolean zoomedIn,
                                              ViewerState state)
```
    Get a "good" initial viewer transform for 2d. for 2d. for 2d. for 2d. for 2d. for 2d. for 2d. for 2d. The viewer transform is chosen such that for the first source,
    - the XY plane is aligned with the screen plane,
    - the z = 0 slice is shown,
    - centered and scaled such that the full dim_x by dim_y is visible.
    Parameters:
    
    viewerWidth - width of the viewer display
    
    viewerHeight - height of the viewer display
    
    state - the ViewerState containing at least one source.
    
    Returns:
    
    proposed initial viewer transform.
  - quaternionAngle
```
public static double quaternionAngle(double[] q1,
                                     double[] q2)
```
    Computes the angle of rotation between the two input quaternions, returning the result in radians. Assumes the inputs are unit quaternions.
    
    Parameters:
    
    q1 - first quaternion
    
    q2 - second quaternion
    
    Returns:
    
    the angle in radians
  - normalize
```
public static void normalize(double[] x)
```
