public Lens(Sphere s0,
            Sphere s1)
```
    Construct a lens from the two spheres. A IllegalArgumentException is thrown if the spheres have empty or single point intersection. Note that the two spheres given as arguments are not stored, and subsequent changes to the lens should be performed through appropriate setters.
- Method Detail
  - getRadius
```
public double getRadius()
```
    Radius of the equator of the lens
  - getFocalDistance
```
public double getFocalDistance(int i)
```
    The distance from a focal point to the equator of the lens
  - getSphereRadius
```
public double getSphereRadius(int i)
```
  - getSphereCenter
```
public Point getSphereCenter(int i)
```
  - getCenter
```
public Point getCenter()
```
    Description copied from interface: Shape
    
    Get the geometric center of the shape. The center of a shape can be interpreted in many ways (center of mass, circumcenter, inscribed center etc.). No strict requirement is given here, but typically the circumcenter should be supplied. This method is most prominently used to find the average center-position of a collection of shapes such that scene-viewers can be centered on the scene.
    
    Specified by:
    
    getCenter in interface Shape
  - overlaps
```
public boolean overlaps(Volume vol)
```
    Description copied from interface: Volume
    
    Determine if this volume overlaps vol. Two volumes overlap if their surfaces touch or if the union of interiors is non-empty.
    
    Specified by:
    
    overlaps in interface Volume
  - getVolume
```
public double getVolume()
```
    The volume of the lens
    
    Specified by:
    
    getVolume in interface Volume
  - clone
```
public Lens clone()
```
    Description copied from interface: Volume
    
    Make a deep clone this volume.
    
    Specified by:
    
    clone in interface Volume
