However LGPL programs/libraries can be linked to from any program, unlike GPL code which does not allow distribution unless all the sources including that of any code which links to it are also distributed with compatible rights but not necessarily obligations. Distributing an LGPL binary you must still distribute its source as well (in one of the ways described in the license). Then you may distribute it under the LGPL license. Apple does not allow GPL software on its appstore. To distribute a program on the appstore you must give Apple a license to distribute it, in return they collect license fees and pay you part of what they collect, but they are not willing to agree to the GPL and are not willing to agree to make the sources available under those conditions. You are not in a position to give Apple any license to distribute expr except the LGPL, and certainly cannot give them the right to distribute it without them agreeing to the obligations regarding expr source code, which would seem to put it in the same situation as GPL programs. But is expr part of libpd??

Re: [PD] need help with gem and glsl feedback
first thanks both for your help.
i was tired yesterday evening.
jack , i have a problem with your patch.
i had already similar problems before, that's why i wanted to use some
shader in the feedback chain .
it works ok BUT with very long feedback ( 0.999 alpha ) values i get a
ghost image,
the point never diseappears( because perhaps of a bad approximation in
opengl ) .
ie : color 1 1 1 0.995
leaves traces
is that a problem with my graphics card ? i don't think so .
i join a clumsy correction test , with makes things flicker a bit too much .
do you have a better workaround?

Re: [PD] LED on the Cheap
I guess some microprocessor like Arduino will be needed for that. Plus shift registers since you'll be using lots of LEDs. Do you wanna use RGB LEDs? How do you want to use Pd in that? Will the panels react to some or image, or something like that?

Hello Patrice,
I just added a line at the begining and an other one at the end of
fractalFeedback.frag to change the alpha for the feedback.
I also change the texunit ID backbuffer to 0 in the patch.
You can change alpha feedback with the number box i added in the patch.
Hope it helps.

It depends heavily on whether your want still images or animation. If you want animation, the difficulty grows with the fps rate. Ie if you want 1 fixed picture per 10 seconds, you can hack something out of an arduino + i2c adressable led strips (check on hackaday.com for hardware sources ; have a look at the peggy 2.0 board). If you want video, ask Chinese factories that make video displays with LED curtains. Then you can hook up a VGA signal into your LED display. It's rather hard to DIY and certaintly not a beginner project.

If the license change was done with the authors consent, it wasn't done properly because, as I said before, the headers in vexpr.c, vexpr_fun.c, and vexpr_if.c are GPL and it prints a GPL load message. The LGPL license is in the LICENSE.txt file: https://github.com/libpd/libpd/tree/master/pure-data/extra/expr~ I could just go in and change them, but I don't know the authors nor have their consent, so I figure this should be done at the source.

Re: [PD] LED on the Cheap
On the topic of arduino controllers--I recently listened to a presentation at the Kansas City Open Hardware Group meeting about Motate. It's an arduino library (and someday a board). https://github.com/giseburt/Motate The author was motivated to write the library for motor control, but it's still applicable to bit-banging in general. He said that his code could reduce the number of clock cycles it takes to toggle an I/O (paraphrased). I haven't dived in too deep, or figured out a test for it--but I thought I'd bring it up, regarding the difficulty with higher fps rates.

It depends heavily on whether your want still images or animation. If you want animation, the difficulty grows with the fps rate. Ie if you want 1 fixed picture per 10 seconds, you can hack something out of an arduino + i2c adressable led strips (check on hackaday.com for hardware sources ; have a look at the peggy 2.0 board). If you want video, ask Chinese factories that make video displays with LED curtains. Then you can hook up a VGA signal into your LED display. It's rather hard to DIY and certaintly not a beginner project.

Re: [PD] LED on the Cheap
I helped build this wall: http://blog.x37v.info/2012/10/10/led-wall Controlled with video. It was not cheap but relative to commercial solutions, not bad at all. For a smaller section like you're talking, it wouldn't be too bad. It is quite bright. My partner posted some of the build details here: http://dorkbotpdx.org/blog/armatronix/led_video_wall These LED strips are much nicer to deal with than trying to build up your own panels with individual LEDs. There are some other LED strips out there too, some that are probably even less dense and likely less expensive if you don't need the resolution. -Alex On Thu, Oct 3, 2013 at 1:58 AM, Alvin Google alvin.os...@gmail.com wrote: I am writing a proposal to use Pure-Data to control LED panels that would light part of a rock quarry.

Re: [PD] [biquad~] as cyclone's [allpass~]?
i hope i guess i figured it out on how to implement it with delay lines. see attachment. And I realize you can't do this with [fexpr~] or [biquad~] because the sample delay length is kinda big for that, right? cheers 2013/10/3 Alexandre Torres Porres por...@gmail.com cool, but do you know how to implement cyclone's [allpass~] with it? It's really unclear to me what is the relation of this pass filter with the one you can generate with biquad coefficients, or with raw poles/zeros objects for that matter. Well, one way or another, it's also unclear to me how to do it with delay lines. seems that it is related to a comb filter, right? cheers 2013/10/2 Chris Clepper cgclep...@gmail.com Allpass for reverb is easy to do with delwrite~ and vd~. I used 32 of them today to recreate a famous 'deep space' reverb.

If your using libpd, you can simple remove the pure-data/extra/expr~ folder and com[ile it without expr. On Oct 3, 2013, at 10:58 PM, Tony Hillerson tony.hiller...@gmail.com wrote: Ok, great.
