Why gridflow is for expert coder people (< 0,00000000000000005 % of
people on the earth ? and maybe < 0,000005 % of the users of PD) is
it for fun ?
You are in your right to continue thus (for 30 people (good luck for
you !) and long life for gridflow !!!!)
thx for you answer.

not necessarily, but people tend to use GEM as much as possible and only use GridFlow for things that they can't do with GEM. On top of that they usually try PDP as well.
GridFlow for beginners tends to be more common at Université d'Ottawa than anywhere else.
GridFlow is more "low-level" in some ways as it exposes more details of what's going on, but this same thing allows for more configurability and genericity. The latter is the ability to use the same objects to do different things on different kinds of data, but especially in the case of GridFlow, in a way that the difference is in how you interpret it, because GridFlow treats everything equally. A cross-fade is done in exactly the same way no matter what you apply it on: images, translations, polygons, sounds, numbers, notes, whatever.
is it for fun ?
It's fun, but it's also quite serious. It's also been used for exhibitions at the museum of contemporary arts of Montréal, the museum of civilisation of Québec, and several gallery exhibitions, but also Claude in the UK has done quite a lot with it. There might be artwork done with GridFlow that I don't know about.
You are in your right to continue thus (for 30 people (good luck for you !) and long life for gridflow !!!!) thx for you answer.
So, what's your point? Do you have concrete changes in mind?

hm, i am sure, that gridflow is used by more than 0.000000003 people on earth ;-)
i wouldn't call myself an expert, but i would call myself a sporadic gridflow user. i used gridflow for an artwork during my exchange at university of ottawa.
i wouldn't say that gridflow is only for expert people, but yes, there is a lot to learn, when learning gridflow. and learning it is very interesting. i don't have an academical/mathematical background and for me gridflow is one of these tools, that help me understand theories, that i wouldn't have a chance to understand whithout seeing them implemented and working. this applies also very much to pd, i think. would you consider pd to be a tool only for dsp experts and academic musicians?

Exactly. GridFlow is designed like Pd is, while GEM and PDP both try to hide much more about video and other data types, than what Pd ever hides. (One hides less, by allowing lots of data converters and data operations in a way that you can access the data the way you want, instead of having to rely solely on readymades)

OK, it seems that GF is a powerfull tool. But why there is no basic
tutorial for beginner to install it ?
Because :
1 : Install Ruby. Make sure it contains ruby.h and intern.h and
related files. It's also recommended to have libruby.so. Those extra
files may be in a package called ruby-dev if you are using RPM or DEB/
FINK. If you are building Ruby yourself, it's better to configure
ruby with --enable-shared, else you won't have libruby.so (but you
will still have libruby.a). If you need to have two Rubies at once,
for example Ruby 1.8 for running Rails and Ruby 1.9 for running
GridFlow, you may build Ruby 1.9 with the option --program-suffix=19
which will help distinguish the two Rubies. It's also possible to
have two Rubies installed without that option, but it might be
complicated. If you install into a system directory, you may have to
run ldconfig after installing Ruby.
2 : Download GridFlow from the website and uncompress it, or get it
from the CVS server.
3 : Run ./configure from the gridflow directory. Make sure it detects
all the components you want to use with GridFlow. If your OS is
Debian or Ubuntu you would run ruby1.9 configure instead so that it
doesn't use ruby 1.8. In MacOS you would normally use FINK to install
those extra components: libjpeg libjpeg-shlibs libpng-shlibs libpng3
libpng3-shlibs libmpeg libmpeg-shlibs
4 : Note: you may have to set CPLUS_INCLUDE_PATH to indicate where to
find *.h files, and you may have to set both LIBRARY_PATH and
LD_LIBRARY_PATH to indicate where to find *.so or *.aor *.dylib or
*.bundle or *.dll or *.lib files.
5 : Note: you can do ./configure --help to get a list of supported
options. You can use them to ignore the presence of troublesome
libraries and select debugging level. With --use-compiler you should
use a version of g++, not directly a version of gcc, else you get
undefined symbol problems. Some versions of gcc/g++ are troublesome.
6 : Run make to produce the executables gridflow.so and
gridflow.pd_linux or similar
7 : With a text editor, create ~/.gridflow_startup and write
something like GridFlow.data_path << "/pd/extra/gridflow/images" to
tell GridFlow where to find additional folders containing images or
movies you want to use with GridFlow.
8 : Ltilib (optional, linux only): The LTI-Lib is an object oriented
library with algorithms and data structures frequently used in image
processing and computer vision.
1 : Download and install ltilib version 1.9.15 from http://
ltilib.sourceforge.net/
2 : in optional/rblti do: make
9 : Loading GridFlow:
1 : PureData : With a text editor, modify or create ~/.pdrc and write
-lib gridflow.
2 : ImpureData : In the ".pdrc editor", add gridflow to the list of
libraries.
3 : plain Ruby : the command require "gridflow" will load gridflow.so.
Note that on MacOS the dot-files are invisible in the Finder but you
do cd ~/Desktop; ln -s ../.pdrc "PureData Configuration" to make an
alias on the Desktop. Note also that on Windows the dot-files are
even more trouble.
- Where to DL Ruby and how to install it (macosx) ?
- OK
- With Macosx, how to use Fink (what we do with it ?) what can we do
with Fink to configure GF ?
4) Set CPLUS_INCLUDE_PATH : where is it and what is it ? Where to
find *.h files : where is it ans what is it ? And you may have to
set both LIBRARY_PATH and LD_LIBRARY_PATH : where is it and what is
it ? To indicate where to find *.so or *.aor *.dylib or *.bundle or
*.dll or *.lib files : idem ?
5) It's like chinese langage for me.
6) OK
7) And we save it on the desktop ?
8) For linux only (equivalent for OSX ?)
9) OK
Note) On MacOS the dot-files are invisible in the Finder : are you
sure ?
I think a clear documentation is good for people like me. Then we
could install GF without problem. This would multiply the chances to
have GF by 10 ? ;).
Why GF is not include with pd-extended ?
Thanx for your answer.

I agree that the setup is difficult. I haven't gotten it to work on OS X yet. Who _has_ installed GF on OS X? I wonder how difficult it would be to make as a self-contained application. It seems to rely on several shared libraries and an installed version of Ruby...not an easy task?

Since GridFlow 0.8.4, Ruby 1.9 is less needed, as it works better with Ruby 1.8 than it used to. Still, some things are messy, and the API of Ruby keeps on changing, even going just from 1.8.4 to 1.8.5, so I can't guarantee anything, but I can help fixing problems, again.

Imho, GridFlow doesn't have enough actual linear algebra in it. The strength is in something more general than linear algebra, which I could call "grid algebra", which doesn't just involve linear operations. The two most common linear algebra operations that are still missing are matrix inversion and eigendecomposition. Coming soon... using OpenCV.
I agree that the setup is difficult. I haven't gotten it to work on OS X yet. Who _has_ installed GF on OS X?
I have, some years ago, but James Tittle was more the expert about GF on OSX.
I wonder how difficult it would be to make as a self-contained application. It seems to rely on several shared libraries and an installed version of Ruby...not an easy task?
I will help anyone is willing to try to make a package.

in the terminal type: defaults write com.apple.finder AppleShowAllFiles 1
then restart the finder and it will display all the hidden files too.
another neat thing i discovered some days ago is if you naviagte in
the terminal to a hidden folder and use the open command it will open
the unvisible folder in the finder (try
open /bin
)

which will help distinguish the two Rubies. It's also possible to
have two Rubies installed without that option, but it might be
complicated. If you install into a system directory, you may have to
run ldconfig after installing Ruby.
OK, i have downloaded it with Fink (install binary package)

You should install gcc 3.x; gcc 2.9.x is no longer supported (you might use --force-gcc3 to pretend at your own risk)
4 : Note: you may have to set CPLUS_INCLUDE_PATH to indicate where to
find *.h files, and you may have to set both LIBRARY_PATH and
LD_LIBRARY_PATH to indicate where to find *.so or *.aor *.dylib or
*.bundle or *.dll or *.lib files.
5 : Note: you can do ./configure --help to get a list of supported
options. You can use them to ignore the presence of troublesome
libraries and select debugging level. With --use-compiler you should
use a version of g++, not directly a version of gcc, else you get
undefined symbol problems. Some versions of gcc/g++ are troublesome.
6 : Run make to produce the executables gridflow.so and
gridflow.pd_linux or similar
7 : With a text editor, create ~/.gridflow_startup and write
something like GridFlow.data_path << "/pd/extra/gridflow/images" to
tell GridFlow where to find additional folders containing images or
movies you want to use with GridFlow.
8 : Ltilib (optional, linux only): The LTI-Lib is an object oriented
library with algorithms and data structures frequently used in image
processing and computer vision.
1 : Download and install ltilib version 1.9.15 from http://
ltilib.sourceforge.net/
2 : in optional/rblti do: make
9 : Loading GridFlow:
1 : PureData : With a text editor, modify or create ~/.pdrc and write
-lib gridflow.
2 : ImpureData : In the ".pdrc editor", add gridflow to the list of
libraries.
3 : plain Ruby : the command require "gridflow" will load gridflow.so.
Note that on MacOS the dot-files are invisible in the Finder but you
do cd ~/Desktop; ln -s ../.pdrc "PureData Configuration" to make an
alias on the Desktop. Note also that on Windows the dot-files are
even more trouble.

OK, i have downloaded them with Fink (install binary package) In terminal : /gridflow-0.9.0 rybn12$ ./configure i get : This is the GridFlow 0.9.0 configurator within Ruby version 1.8.1-2003-12-25 [gcc3] GNU C++ Compiler 3 (or 4):
You need to install g++, not just gcc. This will change many of the results of ./configure.
