| GreatCircle | | public class GreatCircle (Code) | | A stateful great circle calculator.
The theory is presented in
Partial Evaluation - Freeing the essence of a computation.
Two lat,lon points are kept in a 3D unit vector representation.
Once the two points are set, various distance*() and azimuth() function
may be called.
The method position() computes the position of a fractional distance along the great circle between the points.
