- Constructor Detail
  - Line
```
public Line()
```
    Constructor instantiates a new Line object. The origin and direction both default to (0,0,0).

```
public Line(Vector3f origin,
            Vector3f direction)
```
    Constructor instantiates a new Line object. The origin and direction are set via the parameters.
    
    Parameters:
    
    origin - the origin of the line.
    
    direction - the direction of the line.
