Has anyone been able to generate an .xml?
Used Dashcode on the Mac and added some code from an earlier post. Works great! Thanks! Gurl!

I have spent some time making presets for papywizard but they were never quite right
so after members pointing me to the Papyspheric preset maker i read all the info and had a go.
I used portable Python and changed the settings in the program to suite my camera and ran it.
A couple of things that i found that may be useful are that you cannot select and paste the output using the right click mouse
in windows as it does not work so you have to select all the text and use control + V on the keyboard which does copy it all.
The second thing is that if you paste the text into Notepad it makes a bit of a mess even with word wrap selected
which makes it very difficult to see what's going on, i found if you use Wordpad instead it looks the same as the program output
and is very easy to see and edit.
You can save the file as a RTF as a backup which keeps all the text in order when you load it again.
The output for my camera did not look right when i first looked at it and the pitch values seemed as if they would
not work correctly but i spent some time copying and pasting into a XML file for the preset and thought i would test it out.
I was very pleasantly surprised after taking all the images on the Merlin and putting them through Autopano that it stitched
almost perfectly and was one of the best presets i had got so far.
I should have had a lot more faith and would just like to say thanks to the Author Georges (GURL)
for taking the time to write a great little program which is very useful to create presets.
One thing i would love to see if its at all possible and if Georges has the time and this would be that the output
of the program be in a similar order to presets with 0 being straight ahead and +90 at top and -90 at the nadir.
It would make it so much easier to copy the coordinates over to make the preset and probably cut down on mistakes
when copying all the numbers across.
Thanks again

Hello
Python 2.6.4 installed, copied the code and saved as a .py file
module runs but just open another python window with nothing inside ....
What is the problem ?
Thanks

The problem is that papyspheric want Python 3.1 (not 2.6.4)
Though this was probably a mistake, not knowing the customs of the Python country I used the most recent stable version...

Ok i might not be a super coder, but here's a minor edit:
Changed:
1:Now adds "<pict " and "/>" to each pictch/yaw position in the output for easier conversion to xml
2:The direction of each row is reversed relative to the previous, to keep the head from swinging all the way back to the start, i.e will now go:
>>>>>>
<<<<<<
>>>>>>
rather than
>>>>>>
>>>>>>
>>>>>>
3:added a couple more data points to the sensor sizes at the start of the script

I modified the code to write to an xml file, and it takes an argument for focal length. Just setup the script for your camera, and then run it with the desired focal length.

######################After you save the file to a .py, and setup your sensor size. Just run the script with the focal length as an argument. Eg. "python sphere_calc.py 24" will make a xml file called "24mm sphere_preset.xml"
edit: I edited this line in the script:
if len(sys.argv)>1:
at the top of the script and changed the 0 to 1. There is always 1 argument being sent to the script, and that's the script name. So this now either works with the data in the file, or with a focal length argument.

. I got one last question. I have a DX sensor. should i typ in the 55mm DX or the 82.5mm FX ?

Looking at sensor sizes http://en.wikipedia.org/wiki/Nikon_DX_format, a DX is 23.7mm x 15.5mm (depending on camera).
I plan on putting a simple gui to this script since I think it would be a nice tool for people to have easy access to. Hopefully early next week I should have time to finish it up and post it.

I meant that my lens is a DX 18-55, and I want to make a script for the 55mm. Do I have to put in the 55mm or the FX equivalent that is 55*1.5=82.5mm in the script?
Offline
The script uses 24x36 as default sensor size (Hside/Vside). So you need to enter the corrected focal (55 * 1.5 = 82.5mm).
Or you can modify the script with your sensor size:
Vside= 23.6
Hside= 15.8
and then give the real focal (55mm).

Any news on the GUI?
I'm trying to run the script but it doesn't make a xml file. And when i run it in the pyhton GUI (run module) it is completely diffrend and unusable for papywizard.

The zero division error comes from the way different python major releases deal with integer division:
In python 2.x:
1 / 2 = 0
In python 3.x :
1 / 2 = 0.5
If you want a float division in python 2.x, you need to write:
1 / 2. = 0.5
or
1. / 2 = 0.5
So, just change the lines 48/49 from:
trueVfov= degrees(2 * atan (trueVside / 2 / f)) trueHfov= degrees(2 * atan (trueHside / 2 / f))
to:
trueVfov= degrees(2 * atan (trueVside / 2. / f)) trueHfov= degrees(2 * atan (trueHside / 2. / f))

Good job! I added a link to your converter on Papywizard web site...
BTW, I started, some months ago, to re-write GURL's script in a more pythonic way (more object), but I'm stuck on the maths; there are too many global vars and so, and it is hard to find what is needed and what is optionnal.
Could someone re-write the maths in a programming-language independant way? I could then write something more robust, which could be integrated to Papywizard or in another applications...
Thanks!

Hello Kevin,
I wish to thank-you ! 
This is a long time we are all waiting for a Web interface of PapySpheric ...
I have try to save your sources on my PC but without success (the Zip file is empty ...!?)
Could-you see this small problem ?

The problem was the name of the script. I guess the internet doesn't like .CGI files being downloaded or emailed. I renamed the file to a .TXT and put instructions to rename to .CGI in the zip.

Take a look at this script, maybe you will find it usefull. Its more pythonic and way easier to embed, but math there not that good.
