I have an arc of circumference defined by three points, center, start point, and end point; and I want to obtain several points of the arc.
With the parametric equations proposed here it seems not difficult to do. The problem is that my points are defined by latitude and longitude, not x and y coordinates.
Is there any quick way to obtain latitude and longitude of points of the arc, without having to go the hard way (WGS84 conversions etc)?
I have a function based in Vincenty inverse formulae to obtain distance (in NM) and azimuth angle between these points if it can help.
