I have two points A and B on a sphere (or a WGS84 ellipsoid, if using the geographic extension). These two points define a great circle. I wish to find the coordinates of a point M on that great circle, lying at a certain distance from A (going from A to B).
To give an example application: a boat goes from A to B on a great circle: knowing its speed I wish to know its position at a given time.
Any way of doing this with boost-geometry?
Thanks!
