cool, I'm only repeating what I read on that page....I dont really know much about it and since it seems to be down now (cant find it) I was posting here hoping I got some more clarity on it.
Regardless of what the guy there said, what I saw in that page pretty much looked like what Helm linked to as 4 point...although, I couldnt know maybe it was two 5 point perspective pictures stringed together?
What Ndchristie is saying about cylindrical perspective is most likely what was going on,
But the person did atleast reference spherical perspective, he at least linked to one example of spherical view of famous places.
The page showing it was just a small rectangle that could scroll in any direction. I remember the matrix site used to have one...but it's down now.
http://www.revolutionviewing.co.uk/novaloca/spstandard/?keepThis=true&TB_iframe=true&height=570&width=780 this seems to be spherical but...I dont remember the matrix one being so grossly distorting.
EDIT: ok..now that I remember there was not ONE straight line in the "ten point perspective" drawings....and even the 5 point perspective one in helm's has straight lines coming out of the central perspective point, so that's probably why he needed such a ridiculous amount of points.
Maybe the person who made the page was trying to tout his notion of "10 point perspective" Because the page made examples of an imaginay real life situation to back up his claims, the starwars Clonewars thing, and also used a 3d checkered floor to support what he said. Which is why I thought it was a really cute and informative page...and I wish I could find it now :p

AAAANyway, I was just trying to say that maybe using a cylindrical perspective could be useful for scrolling scenarios.....but did not have the terminology to say it.
EDIT: hahahah. Look what I found
http://slash72.club.fr/gurl/MODES-PROJECTION/en_prefecture_rectiligne.htm scrolling perspectiveless pics made out of a bunch of stringed photos...maybe you'll get some ideas off of that!
