Grrrrrrrrrrrrrrr! This one is wonderfull, that's sure!
I am against many pictures for a flat view (ie: only showing the front of a building); but you need a lot of pictures if you want to make a virtual visit in 3D, like this one: in and out, left and right, walls and roof; and it's possible with less pictures. Sometimes you get a point cloud, which can be funny ot useful.
Here we are in a different world (lost in the triangle !!!) probably more then 1000 pics (in one day? one week?) on a computer I can't dream about; and you get a point cloud that shows something which is not on the pics, I mean the view from the sky over the virtual church you can manipulate.
