Re: [PD] Re: [PD-dev] Pure Data for Solaris?
by Jarbas Jacome 06 Dec '06

Yes, brother... thanx, but anyway the workshop was very good! The people become really surprised with the possiblities PD can offer. It was just a very introductory workshop and it worked very well. As it was part of a visual art event, I tried to focus on audiovisual. I translated the summary if you want to know the topics we discussed: http://www.cin.ufpe.br/~jjoj/oficina_pd_english.pdf Thanx everybody! j.jR.

a simple, user friendly place to post and link to patches, externals, libraries, etc.
by hard off 06 Dec '06

06 Dec '06

i'm sorry i have really no idea about how to go about doing stuff on the internet, or otherwise i'd try to set something up by myself, but we REALLY need a place where any pd users can upload their works. i know there is a wiki thing on the iiem site. but barely anyone uses it. i think the main reason being that it's a bit of a headache for simple people such as myself. so i just thought i'd open the doors for some discussion of this topic. what are your ideas? i think we really just need something where people can upload a patch or zip file with one click, and then write a description of it.

Send array values through OSC
by Jerome Tuncer 05 Dec '06

05 Dec '06

Hi everyone, In the process of building some kind of audio oscilloscope in Gem I'm trying to send values from a table/array from one computer's PD to another's through OSC. At the moment, my chosen solution is to have a counter scan the table, then pack the values (X & Y) and send them through a: [send /OSC/Whatever/The/Name $1 $2( Anyway, I do have this feeling that this is not a smart solution. Anyone has ever done it before (send array values through OSC)/has a cleverer idea ? Danke, Jérôme

diff between graph and array?
by derek holzer 05 Dec '06

05 Dec '06

Writing docs sure makes you question the simple things again! Like this: Why is there both "graph" and "array" in the Put menu? Seems like the "graph" option is kind of a crippled "array" insofar as it doesn't actually even have a name to address it. At least *I* never use it when I need to put an array/table somewhere, but maybe somebody has a clever use for it. Is "graph" some sort of evolutionary holdover, or does it have a distinct purpose? Miller's manual doesn't go into details here. best, d. -- derek holzer ::: http://www.umatic.nl ---Oblique Strategy # 4: "Abandon desire"

font to include in Pd-extended packages
by Hans-Christoph Steiner 05 Dec '06

05 Dec '06

I'd like to propose that we include a default font in the Pd-extended packages and that anything that uses fonts use the included font. I know that the aesthetics of fonts are generally very contentious, I would like to avoid that issue entirely. Instead this is an issue of usability. People can use and learn much quicker if there is a default font setup that's easy to use. So we need a font that is compatible with the GPLv2, since Pd- extended is distributed under that license. I found Gentium, which is released under the Open Font License, which is a free license (FSF and DFSG approved). Using Gentium as a default font would not prevent people from using whatever font they wanted, it would just be the default so that font things "just work" when you try them. Also Gentium has very good support for as many languages as possible. http://scripts.sil.org/cms/scripts/page.php?site_id=nrsi&item_id=Gentium Including it in the package is easy. I am posting this email in the hopes that I can get the developers of Gem, Gridflow, PDP, PiDiP and whatever else uses fonts to use this as the default. .hc ------------------------------------------------------------------------ Looking at things from a more basic level, you can come up with a more direct solution... It may sound small in theory, but it in practice, it can change entire economies. - Amy Smith

gem2pdp compilation | once again
by Patrick 05 Dec '06

05 Dec '06

hi everybody i just catched the cvs-externals and compiled pdp, and the cvs-gem sucessfully. now i tried to compile the gem2pdp: #autoconf #./configure --with-gemdir=../../src/Gem/ --with-pddir=../../ --with-pdpdir=../pdp #make clean #make i tried also with the pdp-0.12-4 version ( ./configure --with-pddir=../../../pdp-0.12.4 ) and i get only: cat ../pdp/include/pdp.h | grep -v m_pd > pdp-light.h g++ -DPD -O2 -funroll-loops -fomit-frame-pointer -ffast-math -Wall -W -Wno-unused -Wno-parentheses -Wno-switch -DGEM2PDP_VERSION=\"0.6\" -g -I../..//src -I. -I../pdp/include -I../../src/Gem//src -o gem2pdp.o -c gem2pdp.cpp gem2pdp.cpp: In static member function ‘static void gem2pdp::obj_setupCallback(_class*)’: gem2pdp.cpp:142: error: cannot call member function ‘void CPPExtern::post(const char*, ...)’ without object make: *** [gem2pdp.o] Error 1 what could be the problem? i also tried with #make CC=gcc-3.4 but... the same... greetings.

pdp crop?
by metafor 05 Dec '06

05 Dec '06

hi list i wonder if this might be possible with pdp. i have to do some heavy image processing (filters and colordetection) on 4 videostreams in realtime, which is a overload for my cpu. all frame manipulations like gain/saturation/stresh/cheby are applied on the whole resolution 320x240. but actually i just need to calculate a part of the image where i do the tracking. therefore it would be great if i could crop a region of the stream and start working just with this part of the image which would reduce the data to process drastically. would this be possible within pdp. i think there is no object around yet, but would the concept and structure of pdp allow this kind of operation? any ideas? best marc

Newbie: output~ couldn't create
by Ismael Valladolid Torres 05 Dec '06

05 Dec '06

I am doing my first tries with pd. I am specially interested in learning building my own synths. I've followed this interesting tutorial. [1]O'Reilly -- Make Your Own Music Software with Pure Data 1. http://digitalmedia.oreilly.com/2005/04/27/pd.html However when loading the provided example Simple Synth.pd I get this error in the output window. output~ ... couldn't create Obviously I get no sound. Any ideas welcome! Cordially, Ismael -- Ismael Valladolid Torres http://lamediahostia.blogspot.com/ m. +34679156321 http://www.flickr.com/photos/ivalladt j. ivalladt(a)jabberes.org

[gem] conflicting with [pidip]
by Roman Haefeli 05 Dec '06

05 Dec '06

hi all after having solved all my gem problems (thank you all, shift8, chris clepper and mccormick, cyrille and maybe others, for your patience) and after having written the rule 'do not load multiple externals, when testing externals!' (very important rule!!!! i cannot say that loud enough) on my forehead, i found out, that - besides 3dp, which is obvious - also pidip is conflicting with gem. is that a known issue? when i load both, gem and pidip (no matter, in which order) and i send [create( to [gemwin], i get a message 'fglrx: failed to map depth buffer' to stderr and gem-window freezes showing the background (desktop and/or x-windows). it is not a real problem for me, though. i am just wondering. roman ___________________________________________________________ Der frühe Vogel fängt den Wurm.
