I have 2 points on a sphere, given by $(\theta, \phi)$. How can I find $n$ equally spaced points on the smaller arc of the great circle between them, without converting the coordinates to another system?
I am sure that the smaller arc does not cross the singularity line $\phi=0,2\pi$.
coordinates = {{θ1, ϕ1}, {θ2, ϕ2}}
Thanks in advance.
