I would like to develop a camera type that projects an image at the inside
of a hemispherical surface (as opposed to a flat surface as with
perspective camera). The purpose is to generate wide-angle views (up to
180deg, theoretically). Yes, the widest views would be curvilinear; but up
to ~120deg views should look pretty good. I would like to know: (1) if
someone has already developed such a camera; and (2) if someone can offer a
pointer to a description of the math to do this?
Thank you.

What about reading the documentation ?
Especially the sub-...-chapter about spherical projection in Pov-ray
Reference/Scene Settings/Camera/Types of projection.
(That should be 3.3.1.2.8 of the windows documentation, just launch
povray, hit F1 and there you are!)
So, I believe:
(1) Yes
(2) At worst, you could look at the code of the relevant camera.

It's in the docs and this is not the appropriate forum for this type of
question. This is designed for people who work on the source code of povray.
