Class Sin2

java.lang.Object
skyview.geometry.Transformer
skyview.geometry.Projecter
uk.ac.starlink.ttools.plot2.geom.Sin2
All Implemented Interfaces:
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).
