Some further observations on using stereo:
I tried and work through the little tutorial here:
http://grass.itc.it/gdp/stereo-grass/
Loading images works fine.
Loading and restoring a Desktop works, although the main window
size is not restored correctly and sub-windows are shuffled around
Loading the calibration file 'cal.txt' just crashes stereo.
I suppose the crash is somehow related to the compiler warnings
I reported previously.
Cheers,
Ben

Terry,
this looks like a very interesting software and I would like to explore
it a little more to see how hard it will be to update the user interface
and add any missing features.
A first try to compile on my Ubuntu 7.04 threw this error at me:
gcc -c -DHAVE_CONFIG_H -I. -I. -I.. -g -O2 edit.c
In file included from edit.h:26,
from edit.c:24:
/usr/include/sys/types.h:39: error: two or more data types in declaration specifiers
/usr/include/sys/types.h:39: error: two or more data types in declaration specifiers
edit.c: In function ‘edit_execute_command’:
edit.c:1710: warning: passing argument 2 of ‘edit_printf’ makes pointer from integer without a cast
make[2]: *** [edit.o] Error 1
make[2]: Leaving directory `/home/benni/download/stereo-0.2b/widget'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/home/benni/download/stereo-0.2b'

The culprit is in global.h. If I comment out all declarations for
quad_t (these are in types.h on my system), the software compiles.
I think that the configure script should be modified to detect a
declaration of quad_t on more recent systems.
Attached to this message is a log of the compilation run. There
are some warnings that worry me:
edit.c:1710
mathfuncs.c (asm)
stringtools.c:509
display.c:116
simplex.c:230
I feel that I do not understand enough about stereo to fix these at this
point. Could you look into them?
Anyhow, thanks for breathing new life into a very useful piece of
software!
Cheers,
Ben

Hullo All,
The photo-metrology software, originally developed by Paul Sheer is now established as a Sourceforge project.
It is hoped that some help can be found to further develop this software.
It should be helpful to anyone wishing to build dem data for limited areas, and enables the user to provide their own stereo photo pairs. The fact that camera positions can be arbitrary significantly reduces the difficulties in preparing the raw data needed.
The web site is at <http://stereo.sourceforge.net>.
If you know of anyone who might be interested in this software please point them to it.
Anyone who could help with further development can contact me through this list, or at tduell@users.sourceforge.net.
Cheers,
