There's a GridFlow <--> Gem bridge, and a Gem <--> PDP bridge too.

if you're on Linux you can use GridFlow to do this kind of stuff (and much more)

I suspect gridflow will do what you're after (if you're on Linux, and maybe OS X).

http://gridflow.ca

there's a few cellular automaton examples bundled with it, I think you could hack them apart and rebuild them to do what you want.

Hi nestor, this one? http://puredata.hurleur.com/sujet-1753-linux-ruby-gridflow-compilation-problem

I don't have a ruby problem, I was just wondering about the other errors, none of them matter too much it just means I won't have quick time support etc. I looked at config.log, just about figured out what some of it means.

I got Gem support by adding the path to the src folder, which is what it plainly says you need to do in the instructions. Sorry for being an idiot. I did need to rename configLinux.h.in though, and it says its found Gem08 when I'm sure I've got Gem09 source files.

the objective C++ error is because its looking for that file in the gridflow folder, it ain't there.

the quick time errors are gcc errors not can't be found errors, so I'm not going to pursue. There is mention in the installation instructions that some gcc,g++ versions are troublesome...

I made anyway, and the gridflow.pd_linux file was created, which I got loaded by putting it in the extra folder and editing default.pdsettings, and the examples work fine.

When I create '#labeling' it has four inlets and no outlets, any one used this before? It seems like a really cool object, would love to use it...

I'm trying to compile Gridflow on Ubuntu 8.04 Hardy on a Pentium4 laptop.

Has any one succesfully comiled on ubuntu?

I have been able to get so far using the synaptic package manager to find most missing things, (when I do it again on my desktop I'll write down all the packages I needed and post it here for others) but I am stuck on a couple for things that I can't find info on in the forum. I have PD-extended which I installed using the deb installer.

When I run ./configure I get

What I can't figure out is:
I have a Pentium 4 with mmx, I have installed NASM and I found a package called intel2gas but it didn't help. No idea what to try next.
I have a quicktime.h in /usr/include/lqt so not sure why it doesn't find it. I haven't edited the configure file and the INCLUDE_PATH is already set to /usr/include.
Where do I need to put the gem source files? I downloaded the gem files and I have the src folder with all the source files in it...
Whats the benefit of getting openCV? Do I need the dev packages too?
And I have gobjc++4.2 installed which says its a GNU Objective C++ compiler, is this what I need, + how do I get gridflow to find it?

I had a look at the configure file but couldn't make sense of it.

Please can any one offer any hints? I really want the '#labeling' thing I read about here http://createdigitalmotion.com/2007/01/18/open-source-motion-tracking-with-multiblob-for-gridflowpd/

ps the article says to get pure:dyne, but it doesn't have the latest version of gridflow but I do know its getting a big update and switching to debian installer soon

read the gridflow installation instructions - there is no real install method, but:

ln -s /path/to/gridflow /usr/local/lib/pd/extra/gridflow

I had luck with changing 'ruby' to 'ruby1.9'

I've installed all the libs (-dev versions too...) Here is the output of ./configure:

PureData support is required (since GridFlow 0.9.0)
generating ./config.make
generating config.h
See ./config.log if you want the details of the configuration tests.
If you are satisfied with that configuration, you may go on,
and do "make". "make install" is not needed anymore,
just move your gridflow directory to "lib/pd/extra".
If you get stuck, you could contact the author about it,
but first make sure you read "doc/install.html".

I understand that I may need to update the CPLUS_INCLUDE_PATH or LIBRARY_PATH, but I amo not sure how to do this inclusively, for all this various libraries. Is it done in the .bashrc file? I'm going to go ahead and 'make' and see what happens.

hi, I have just built gridflow on my ubuntu box as part of my efforts to find software/ an API where I can manipulate images/movie frames at the pixel level.

I'm trying to do some proof-of-concept kind of things with gridflow now - the simplest being to sort component pixels according to colour etc.

to me, #grade looks like it may be the key object (when combined with others). What I really need are some examples of building a sorting patch using #grade - or ways of working iteratively upon the contents of grids.

Gridflow is very elegant but unfortunately a little beyond my comprehension at this point: I get the feeling that this is due to the design: that it allows you to do complex processing & operations with a minimum of objects involved.

anyone got some pointers/ideas?

Ash

Can you post your resulting patch so far? I would love to have a look at it.
I did a moviefader, and i know that video working is not quite nice.

If you can, try to have a look at GridFlow:
http://gridflow.ca/

If you are giving up, then try vvvv:
http://vvvv.org/tiki-index.php
It's much better for video purposes, it's its origin.

there is a new version of gridflow...I think it now supports ruby .8 so I reckon those complie headaces i got using osx might go away with this version...Ive wanted to use gridflow for ages!
