Robert, this is really extremely good stuff!
When I saw your first post, I was certain that you are some sort of professional 3D-artist or surveyor.
I shall add one of my humble projects - quite different in scale.
For me, orthophotos are the goal and the 3D-models are just the means to an end.
The challenge was an ancient tree standing directly in front of the building, allowing only for 1-3 meters of distance…
My equipement is rather humble, a mere LX100. :oops:
But nevertheless, the result is entirely ok.
Even though I used only jpegs and the glas facade on the left gave me a bit of trouble, the accuracy is still within a couple of mm…
