```
    Project a point from the sphere to the plane.
    
    Specified by:
    
    transform in class Transformer
    
    Parameters:
    
    sphere - a double[3] unit vector
    
    plane - a double[2] preallocated vector.
  - validPosition
```
public boolean validPosition(double[] plane)
```
    Description copied from class: Projecter
    
    Is this a valid position in the projection plane for this image. This default is appropriate for all projections where the projection plane is infinite.
    
    Overrides:
    
    validPosition in class Projecter
