Thanks Alex I can recommend the Carroll/Agrawala/Agarwala paper for its very clear exposition of the mathematical basics of spherical images and wide angle projections.
Their way of generating custom projections through numerical optimization seems to have been simplified and improved since last year, but still is a bit of overkill in my opinion. In most of their examples, it comes up with something quite close to a squeezed Panini projection, which as we know can be created without drawing a lot of straight line constraints and without massive computation. However in certain cases I would say this approach yields images that might be hard to create by any simpler method. I am of course disappointed that they still fail to mention the Panini projection and the several software packages that implement it. I suppose part of the reason is that there is no properly academic publication on the Panini for them to cite; however I am fairly sure Carroll and Agarwala at least have both heard of it.
