I got a photograph of a housefront.  Taken slightly "off" (the camera's 
axis
isn't perpendicular to the front).

I know the real <x,y,z> coordinates of 3 points of this housefront.

I'd like to use POV-Ray to "tilt" the image and render a view which
should look as if I took the picture with the camera axis perpendicular
to the front. (il will become "orthographic").

I have very little clue about how to process. (I know I have to perform
rotation on 3 axis, a translation, and position camera, but I can't
find the mathematical way...)

Thanks for any help.

Fabien.
