Hi Darek.
a longer time ago, I also wrote such a software for reverse engineering.
You can download this freeware from my homepage www.helson.at. There
select "Download software STUNDLIN"
Good success

Hi Darek and all
There is a feature in my program Shadows Pro to reverse engineer a vertical
sundial from its picture. It does not correct aberrations due to the camera
objective but if the picture is taken exactly in front, it works pretty
well.
You can see a screen copy on this page: www.shadowspro.com/en/gallery12.html

Objet : 2 questions: declination& animation
Dear Diallists
I've got two practical questions:
1. Let's say I have a photograph of a sundial. I do not know where it was
originally located. Is there a way to discover the values of the declination
and latitude it was designed for? There are clear hour and declination lines
on the dial.
2. A friend of mine is helping a student in an attampt to reconstruct an old
missing dial. They need a software which allows to make an animation of a
shadow's path over the dial. Is there anything that would help them?
I would be most grateful for any suggestions.
