Hey, Yuv, Take a look at the 3 latest posts. It seems that Dan, Max and I now agree on how to do this projection.
Max's "Recti-Perspective" and my "Pannini" were already the same, and now Dan's mathlab implementation is, too. It is not the same as the ones from Dan you are considering here (incl. the one in pano13). Not that that one is necessarily bad...
