dear Darek
I haven't a software for your purpose but I use a 3D software to get movie
from a 3D drawing.
Usually I draw the sundial, then I set the position of the Sun, altitude and
azimuth, every 2 minutes for the latitude and the date (usually for equinox
and the 2 solstices). In this way the software builts a series of rendering
and packs them in a movie.
Obviously I can get the movie, or single frames, from any point of view or
any lightining.
The time to get the rendering may be very long (I remember a movie got in 4
days, uninterrupted), it depends by the number of frames and their size, but
it is a PC to work, not me :-)
You can see one of these movies on youtube (it is a low resolution example):

If you think I may help you with this solution, please send me other
details.

Subject: Re: 2 questions: declination & animation
Thank you all for your kind answers, tips and patience - those were very
helpful and I found the data I was looking for.
However the other question remains unanswered and I would very much like to
help my freinds.
So the second one again:
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?
