What would be most usefull would be the ability to enter rotational info from a gigapan or similar head and then have control points picked strictly from the overlap. It would create a much better starting point and be much more efficient than searching for matches across hundreds of images. mgg On Apr 18, 5:59 am, Christopher Allen <cpcal...@gmail.com> wrote: > On 18 April 2011 11:11, Simon Oosthoek <soml...@xs4all.nl> wrote: > > > On18/04/11 08:02, Calvin McDonald wrote: > > >> If I ... > >> [ Do everything perfectly ] > > >> Can I expect to get successful stitches from Hugin without any control > >> points? > > > In the most optimal case, you need at least 3 control points with a > > neighbour on each image you want to include in the stitched result.
