thanks, Terry. Just installing libvigraimpex-dev fixed it. It builds.
Have not tried to run the binary and won't have time to do it in the
next two weeks, but at least my box is up and running with all the
software installed again.

one thing I notice: the Hugin icon does not show in Kubuntu's Kickoff
Application Launcher. But that's cosmetics...

You need to have vigraimpex lib installed on the system. It may be
able to be built using the vigra in hugin but I haven't managed that.
A solution was given in this thread (thanks to Harry)...

http://groups.google.com/group/hugin-ptx/browse_thread/thread/22215e19c32d753b

and the essential bits were...

- cd inside the panomatic-lib source directory (not src)
- make a build directory like "mkdir build"
- cd build;
- issue the following commands to set CFLAGS and so on correctly:
export PKG_CONFIG_PATH=/opt/local/lib/pkgconfig
export CFLAGS="-I/opt/local/include -L/opt/local/lib"
export CXXFLAGS=$CFLAGS

- still inside the build directory issue the command "cmake
-DCMAKE_BUILD_TYPE=RelWithDebInfo .." or simply "cmake  .."
- make

I had to edit this for Fedora for my include and lib dir.
I then installed the binary in my /usr/local/bin and the library in
my /usr/local/lib64, and all worked like a bought one.

Hope this helps.

Cheers,
Terry

[hugin-ptx] Pablo's CP detection tool in Ubuntu

2010-01-23 Thread Yuv
Hi all

I've staged a clean Ubuntu 9.10 on a new hard drive and I've taken it
as a chance to go through the instructions at [0] and check if they do
work on a clean install. Indeed there were a couple of dependencies
and small changes to add to the instructions. The one thing that no
longer works for me is Pablo's CP detector from Launchpad [1].

cmake quits with the following error message:

CMake Error at CMakeModules/FindVIGRA.cmake:49 (MESSAGE):
  Could not find VIGRA
Call Stack (most recent call first):
  CMakeLists.txt:30 (FIND_PACKAGE)

I swear it used to work on my previous 9.10 (upgraded and updated over
the years from 6.06).

what am I doing wrong?

happy weekend
Yuv

Hello,

I think there is a misunderstanding. autopano-sift-C svn trunk is known
to be broken, but not hugin svn trunk.

[hugin-ptx] hugin fast preview problems persist (some slow ones too)

2010-01-23 Thread Tom Sharpless
Hello all

The fast preview still does not handle the general Panini projection
at all well unless the source is a single image.  This may be a
problem with the new code for dynamic FOV adjustment, as there are
similar problems with the biplane and triplane projections now.
Moreover even the old reliable slow preview sometimes has trouble with
the gPp and a stitched source.

I just committed a fix for a discrepancy between forward and inverse
gPp in hard squeeze mode, however that did not affect these problems
noticeably.

So I am appealing for help to those of you who are familiar with the
design of the hugin previews.  Please have a look at the current code
and the recent changes, and see if you can figure out what is
happening.  As test cases, I would suggest 1) a small panorama stitch
from fisheye images (bad behavior) 2) a single equirectangular pano
(good, as far as I have seen).  3) a single fisheye image (a few
glitches?).  I have not tried a stitch from small images.

I doubt this is a problem in libpano code, though would not rule that
out.

Regards, Tom
