Well, this is an interesting point. I also shoot the horizon row
first, then the zenith, then the nadirs. That is, I don't proceed
top to bottom or bottom to top but shoot the middle row, the top
"row" and then the bottom "row."
For me, the assumption that "pictures that are next to each other
in the shooting sequence are also next to each other in the
panorama." will be incorrect.
The multi-row option is more sophisticated than this, matching
consecutive images is only the first step in the process. It is
able to deal with rows or columns in any order.
Does this require using a pre-aligned panorama (as below), or is it
expected to succeed with images in the project in any order and all
beginning placed at 0, 0, 0?
On the other hand, if I (we) are shooting a sequence that is
standard for us, it seems that using a Template would work. Apply
the template would distribute the images in close to the correct
locations on the sphere. Then the trick would be to get the
control point generators to generate points only between adjacent
images.
Yes you can do this in Hugin currently, use an existing project as a
template with the File -> Apply Template function, then use a
'prealigned panorama' control point detector preset.
Out of curiosity, is it the *control point generator* that
"understands" to create control points only between overlapping
images, or is that some information that Hugin generates and passes to
the CP generators? Or...?
This is definitely the most efficient way to align multiple
panoramas taken with the same setup.
Sorry, we are really suffering from a lack of documentation
considering how often we get requests for features that already exist.
Since I believe you work with Linux, you may not be to aware of the
Macintosh text editor TextMate. The interface is very simple looking,
but it packs a *huge* amount of functionality. "Requests for features
that already exist" are fairly frequent on the discussion list. Also,
requests for help figuring out a complicated way to achieve something
when the right use of a menu command will do the trick. ;)
