It's a bit off-topic for the Mesa list - this is a more general 3D topic
and a general-purpose OpenGL mailing list might have been a better choice.

However, briefly:

  I recently made a computer game that plays inside the classroom of
my sons' math class.

  What we did was to take photos of all of the walls of the classroom
from a square-on direction (as far as possible), then a sample of the
floor and ceiling tiles.  Those were then massaged in GIMP to adjust the
perspective (they weren't perfectly square-on), to adjust the lighting
so it matched from one wall to the next - and do remove things from
the foreground of the image that shouldn't have been there.  We also
made pictures of the view from the window and painted transparency
where the panes of glass were in the classroom windows.

  The resulting photo's were textured onto the inside of a 3D model
that we built from measurements of the room - and the various desks,
tables, book cases, computers, TV's and chairs modelled and textured
with images of their real-world counterparts...and a couple of large
polygons outside the window with the outside view textured onto them.

  This was then rendered in realtime on 3D graphics hardware - so we
could show my son's classmates what it would be like if you were a
fly walking upside down across the ceiling of the classroom - or what
the view would be like if you were sitting on top of the bookcase.

  Making a movie from something like that would be very easy.
