I have photo of a room with three walls and floor/ceiling or both. I am trying to reconstruct this room in 3d asking user for minimal input. Right now I use 8 points defined by user, angles of left and right wall(they can be quite different from 90) and one size "InLeftBottom-InRightBottom"(I need to have real size of this room for later use). I have no info about user's camera(I can read EXIF to get FOV and use constant height but this can be only used as additional info).

Is this possible to ask user for less info? Maybe it's possible to get wall angles without user interaction? Or maybe I am completly wrong and should use different approach?

I have always been skeptical of rewriting working code - porting code is no exception to this. However, with the advent of TDD and automated testing it is much more reasonable to rewrite and refactor code. Does anyone know if there is a TDD tool that can be used for porting old code?
