Recommended panorama viewer? Hints for using pannellum?

[Michael Below]

Hi,

I just created my first panorama using hugin (2013-0-0, on Debian testing). It's a 298 by 22 degree partial panorama, a view from a mountaintop, about 48 MPix (22 MB jpeg/320 MB TIFF).

Now I would like to show this to my friends. What is your recommendation for a web based panorama viewer?

Opensource panorama viewers for partial panoramas seem to be rare: For some flash viewers listed here: http://wiki.panotools.org/Panorama_Viewers I found broken websites that had not been updated in years. The pannellum HTML5 viewer looks good, but I couldn't get it to work:

I have tried the current master branch from github, with the partial option, and I have tried the stable branch from github as well. In both
cases, pannellum says it is working for a short time (the waiting symbol is shown), but then just black is displayed instead of my image.
Also, it doesn't make a difference if I use cylindrical or equirectangular projection.

Any hints?

If it helps, I'd be glad to send you a link to my image, I just don't want to put the link into a public web archive.

Cheers

Michael

I got a quick reply from the pannellum author: Pannellum loads the image
as one WebGL texture. Textures have a maximum size of 4096 or 8192
pixels, my image exceeded this, so it couldn't work. With a downscaled
version, I get to see an image -- but it seems to be shown as 360*180
degrees, not my 298*22 degrees. Now I just have to find out how to get
the scaling right.

Hi Michael,

among free solutions I used to use Salado Player (flash) and VR5 (HTML5), but the easiest way to share, IMHO, is to create a free account at 360cities.net and upload your equirectangular. TourWrist is another option. Take a look at this article, where I mention this and other tips:

Thanks. Your article got me to try & build panini. This didn't work out:
The SVN repository mentioned in the wiki is no longer there, the
alternate link offered in the sf.net error message doesn't seem to work
either. When I downloaded the ZIP from sf.net, qmake complained that I
am not using subversion 1.5 (instead I use a current version), and when
I ran make, it stopped with this error:

/usr/bin/ld: build/pvQt_QTVR.o: undefined reference to symbol 'inflate'
/lib/x86_64-linux-gnu/libz.so.1: error adding symbols: DSO missing from
command line
collect2: error: ld returned 1 exit status

Then I tried building panoglview instead. I got as far as running
the ./bootstrap, which complained I had no automake -- in fact, it ist
checking for automake 1.7 to 1.11, and I have 1.14 installed.

Is there a panorama viewer that can be built on a current Linux system?

Cheers

Michael

I would say panini is, although I didn't try to build it myself. Panini is available (as a binary deb package) for and is running great on Ubuntu through the Hugin PPA, so I'd guess something similar is for Debian.

If not, maybe you can use the Ubuntu deb on Debian? At least, I was able to install panini that was built for Ubuntu 12.10 "Quantal" (i.e. two Ubuntu releases old) on my system running Ubuntu 13.10 "Saucy" without any problems, simply by downloading the deb file and running dpkg -i on it, having taken care of iys dependencies. Debian and Ubuntu being quite similar, perhaps you can, too? Anyone having any experience with that?

I had no problems on ubuntu (12.04).

This are the last showed commands:

The created 'Panini' works here.

You could patch bootstrap to accept 1.14
I didn't try, I have only version 1.11.3.

Probably my QT version is too new, or something like that. I am running
Debian testing, with QT 4.8.5, while Ubuntu 12.04 seems to include QT
4.7.4.

In full, the error message looks like this:

The best candidate looks lite it were some broken lib (namely /lib/x86_64-linux-gnu/libz.so.1)

Here, the symbol inflate _is_ defined in libz.
Don't know better, sorry.

Hi,
Panini is missing some of the libraries on the linker command line. To
fix it, open the panini.pro file and add

LIBS += -lGLU -lz

Preferably somewhere in the beginning, because I don't know if it
would work otherwise.

[Carlos Eduardo G. Carvalho (Cartola)]

Oh, yes, I guess that what Lukas said might solve, as I've written here in my wiki:

http://www.cartola.org/cartola/index.php?title=Installing_Panini

The Portuguese version is a little more up to date, including a package installation how to. Maybe you can translate it with google:
