We may use POV-ray as a powerful stitching software, to stitch pictures and
assemble panorama. This is quite simple, for example:
create boxes, same width/height ratio than the pictures
texture the boxes with pictures image map
"translate" the boxes on a distant sphere, positions shifted as the
different pictures to stitch.
Finally, add a camera on the center of the virtual sphere...
I post an image made by the Rover Spirit to illustrate the result (images
thread)

Impressive. Only in the sky pigments are the stitches, slightly visible. I
suppose that you put a light also at the camera position? I am surprised
that you don't see the slight angle that the boxes must have one to another.
Must be the light. Instead of boxes, you could use also polygons (easier to
map?)

Thomas: thanks for your coments. No lights used. Just a simple finish:
ambient 1 diffuse 0. Ambient may be slightly tuned >1 or <1, to adjust
images brightnesses (blending). Although doing that on a first step with a
dedicaced sofware (PS, the Gimp...) is far better. You're certainly right
about using polygons instead of boxes. Polygons, or another sort of patch
object, associated with UV_mapping is probably a powerful way to morph and
finely stitch difficult images. I will try. I guess we may probably control
a lot of stitching processes needed to assemble Panoramas with use of
POV-ray.
