Sin2 (Starjava TTOOLS API)

java.lang.Object
- skyview.geometry.Transformer
- - skyview.geometry.Projecter
  - - uk.ac.starlink.ttools.plot2.geom.Sin2

All Implemented Interfaces:

java.io.Serializable, skyview.Component
```
public final class Sin2
extends skyview.geometry.Projecter
```
Sine (Orthographic) projecter implementation.
This class is copied from the Skyview original class skyview.geometry.projecter.Sin. Apart from changing the name to Sin2 (which is significant since some implementation behaviour is name-dependent), it just shuffles the order of the coordinates so that the tangent point is at (1,0,0) instead of (0,0,1).
