Hi list, I'd like to know if there is an object or an abstration to output the grayscale values of each pixel of a low resolution video, in order to use those value to control the behaviour of 3d objects. Should i use gridflow ? Any ideas/hints would be welcome. cheers pablo
The extraction is easy with GridFlow (for example, [#export_list]), and the 3D could be done with Gem.
Hi. I'm not having any luck finding GridFlow, or any documentation. I found a few dead links... anyone have a live one?

Thank you for the answer, i'll try each of the solution to see which one fits best my needs. By experience will one of them be faster and more stable? By the way I compiled gridflow from cvs , but I can't load it:
./gridflow.pd_linux: ./gridflow.pd_linux: undefined symbol: _ZN9CPPExtern10m_holdnameE gridflow: can't load library
I've tried with gcc4.1 and 3.4, on an ubuntu32 system. Sould I use the 8.4 release instead of the CVS one or am I missing something ( config is fine and find everything it needs) ...

you need to load Gem before loading gridflow with the gridflow<->gem bridge

"open some_image.jpg" -> [#in] -> [#rgb_to_greyscale] -> [#export_list] -> [print]

I'm running the latest cvs on such a system and everything look ok. Maybe we can troubleshoot your installation on #dataflow (irc.freenode.net)?
Cheers,
