I'm trying to come up with a conformal map between a planar triangle and a spherical triangle that's reasonable to implement in software. The big problem is that what I have now involves the inverse of a hypergeometric function, which isn't closed-form for the arguments i'm interested in, and naively numerically inverting it is slow.
There must be a more sophisticated numerical algorithm to do this kind of thing...
