Given a photograph for a background "plate", I want to
render an object in POV that will be composed into the
photo. So, I need to make the camera position and
perspective match the photo.
Given a square of a known size in the x-z plane visible in
the photo, supposing one corner of the square is the origin,
has anyone already made a script or spreadsheet or something
to figure it out? That is, given the length of the two
sides and the angle between them, calculate the camera
position.

This make me think of a great tool I found when I was using windows.
It's name was "Photo Modeler 3d". It was able to take a bunch of photos
with "common points" and give a 3d model of the object. I've tried to
reimplement this thing by myself but never managed to do it ://
Maybe if someone know the process he could help both of us :))

By now you should really know where to post binaries and where not to do so!
