Hi all,
My name is Steven Williams and I am in my fourth year studying
mathematics at Walla Walla University. I just saw the GSoC advert and
thought Hugin would be a fun thing to work on this summer. I have been
using the program for a few years now and have a Canon Digital Rebel
XTi. Several of

It should be straight-forward to calculate the maximum parallax error

yes, I really enjoyed it. its really impressive work done.
Jeffery what are technical details of equipment (camera, lens etc) used for
it? How you calculated exposure for such a huge mosaic.

It is very unlikely the entrance pupil of your lens coincides with the

I managed to set up my workspace today, with the instructions on the

I test-built both Enblend and Hugin, no problems.
I'm going to familiarize myself with the code tomorrow and produce a
