Thanks, but I was thinking more of a technique where you already know which 
points on the image are also on other images, rather than where you have to 
deduce them.  For example, I could take a few images of a simple cubistic 
object, the point out "this point is the top left corner of the doorway in 
this photo, and that point is the top left corner of the doorway in that 
photo".  I saw an article long ago about that but didn't learn the math.

Yeah, I gathered that from his 425 photos of that one little pile of rocks. :-)

I just thought it was cool. :-)  I like easy ways to get models.
