Hi Jim,

I'd say the floor example is aligned as well as could be expected with just a tilt and shift.  Or has the magnification (or Z distance) been optimized too?

Anyhow, to do much better would probably require lens calibration, and some higher order corrections. 

Ultimately, the nadir matching problem needs 3D depth analysis and some "orthophoto"-type local adjustments.  Perhaps we should think seriously about reviving morph-to-fit?

Regards, Tom

Looks like it is working.
The tilt model aligned the spherical images better in your example.
But your wall example looks bang on.
Thank you.  I'll be running some test shortly.
