Hi All, I found that there is a Pd library called pix_opencv in the pd- extended source folder, but I can't load (red dot line box) the externals with the already compiled app that I found here : http://puredata.info/downloads/ Mac OS X Intel (Mac Pro, MacBook, all Intel Macs) http://downloads.sourceforge.net/pure-data/Pd-0.40.3-extended-macosx104-i38… does that mean that it is not working yet? or just that it's not yet in the official distribution? (I tried to compile it myself and now they compile and load but they don't do anything...) please help, loic

[GEM] gemwin attribute
by Jaime Oliver 23 Jan '09

23 Jan '09

Hi all, I remember there being a message to 'draw' whatever gl-shape was in the gemwin so that if you turned that shape off, it would stay recorded in the gemwin, but I can't find it in the help file. Could anyone refresh this for me? best, Jaime -- Jaime E Oliver LR joliverl(a)ucsd.edu www.realidadvisual.org/jaimeoliver www-crca.ucsd.edu/ www.realidadvisual.org 858 202 1522 9168 Regents Rd. Apt.

reading encrypted files - gpg agent is not available in this session
by Ingo Scherzinger 23 Jan '09

23 Jan '09

Hi everyone, I need to be able to read some GPG encrypted files within pd. I can unpack the file using a command line with [shell]. However I get an error message (appearing only in "nogui") saying: "gpg agent is not available in this session". So the file gets copied to the destination file but is still encrypted. Both, in the graphical and nogui system. Doing the same thing with the same command lines in Ubuntu 8.04 using the console I don't get any errors. Any ideas if GPG has to be enabled for pd? If yes, how? Well, the problem may also be sending the password. I simply delayed a second message to send the password to [shell] after sending the decrypting message. Thanx for any ideas, Ingo

Re: [PD] PD extended very slow loading patches
by Hans-Christoph Steiner 23 Jan '09

23 Jan '09

Hey, Let's keep this on the list so that everyone can benefit. The problem is caused by the [zexy] object in labelslider. If you change that to [import zexy] or whatever the same thing is with [declare] (I think its [declare -stdlib zexy]), then the problem will go away. .hc On Jan 21, 2009, at 4:49 AM, kristof lauwers wrote: > hi Hans, > > Sorry for replying late. i've been working with vanilla pd in the > mean time because i had some things that had to be done urgently.. > Now i installed the extended 0.40.3 again. > Actually the loading goes slow every time with most of my patches, > especially the ones with several gop absractions, which usually > takes some minutes. > Attached is a more simple patch (gm_filestretch.pd - it uses the > labelslider abstration i also attach) that also takes more than a > minute..

gemlist/spline_path issues
by Jeff Siegel 23 Jan '09

23 Jan '09

Hi guys. So I'm relatively new to PD, and right now I'm trying to make a set number of discrete objects (20 of them) created along a spline path. In the cityscape1 subpatch in the patch below, I've set up an array to be randomly populated on a bang from the main patch screen. I'd like the objects in the gemlist in the cityscape1 subpatch to use that array, via spline_path, to generate each object's y-axis value. Obviously, how I've set it up is simply creating a straight line of evenly placed circles, rather than conforming to the path as set. What am I doing wrong, or is there another way to do this? Thanks. ----Attachment---- #N canvas 1282 113 450 300 10; #X obj 60 185 gemwin; #X msg 45 159 create; #X msg 103 159 destroy; #X msg 83 124 dimen 1024 768; #X obj 25 189 tgl 15 0 empty empty empty 17 7 0 10 -262144 -1 -1 1 1; #X msg 43 93 lighting 1; #X msg 50 67 lighting 0; #N canvas 0 22 450 300 letterbox 0; #X obj 26 34 gemhead; #X obj 26 59 color 0 0 0; #X obj 26 85 translate 0 5 0; #X obj 26 112 rectangle 9 2; #X obj 136 85 translate 0 -5 0; #X obj 135 112 rectangle 9 2; #X connect 0 0 1 0; #X connect 1 0 2 0; #X connect 1 0 4 0; #X connect 2 0 3 0; #X connect 4 0 5 0; #X restore 201 76 pd letterbox; #N canvas 1252 399 602 414 cityscape1 1; #X obj 31 24 inlet; #X obj 320 -3 inlet; #X obj 31 51 alpha; #N canvas 802 631 450 300 lightarray 1; #X obj 19 13 inlet; #X obj 20 147 randomF 1; #X obj 20 69 f; #X obj 55 68 + 1; #X obj 19 39 metro 100; #X msg 20 120 stop; #N canvas 0 22 450 300 (subpatch) 0; #X array lightarray 8 float 5; #A 0 0.954794 0.628871 0.729569 0.513401 0.95223 0.916195 0.635712 0.717297; #X coords 0 1 7 0 200 140 1; #X restore 178 23 graph; #X obj 21 200 tabwrite lightarray; #X msg 87 67 0; #X obj 55 94 - 1; #X obj 55 120 sel 7; #X obj 20 172 moses 0.5; #X obj 87 172 * 2; #X connect 0 0 4 0; #X connect 0 0 8 0; #X connect 1 0 11 0; #X connect 2 0 3 0; #X connect 3 0 2 1; #X connect 3 0 9 0; #X connect 4 0 2 0; #X connect 4 0 1 0; #X connect 5 0 4 0; #X connect 8 0 2 1; #X connect 9 0 10 0; #X connect 9 0 7 1; #X connect 10 0 5 0; #X connect 11 0 12 0; #X connect 11 1 7 0; #X connect 12 0 7 0; #X restore 320 25 pd lightarray; #X obj 31 73 t b a; #X msg 31 96 20; #X obj 31 119 until; #X obj 31 143 gemlist; #X obj 31 166 circle 0.1; #X obj 32 214 gemlist_info; #X obj 103 240 unpack f f f; #X floatatom 102 268 5 0 0 0 - - -; #X floatatom 139 268 5 0 0 0 - - -; #X floatatom 175 268 5 0 0 0 - - -; #X obj 217 268 spline_path lightarray; #X obj 32 190 translateXYZ 0.1 0 0; #X connect 0 0 2 0; #X connect 1 0 3 0; #X connect 2 0 4 0; #X connect 4 0 5 0; #X connect 4 1 7 1; #X connect 5 0 6 0; #X connect 6 0 7 0; #X connect 7 0 8 0; #X connect 8 0 15 0; #X connect 9 4 10 0; #X connect 10 0 11 0; #X connect 10 1 12 0; #X connect 10 2 13 0; #X connect 12 0 14 0; #X connect 14 0 15 2; #X connect 15 0 9 0; #X restore 203 210 pd cityscape1; #X obj 202 111 gemhead; #X obj 203 135 rotateXYZ 0 0 0; #X obj 203 160 translateXYZ 0 0 0; #X obj 278 184 bng 15 250 50 0 empty empty empty 17 7 0 10 -262144 -1 -1; #X connect 1 0 0 0; #X connect 2 0 0 0; #X connect 3 0 0 0; #X connect 4 0 0 0; #X connect 4 0 12 0; #X connect 5 0 0 0; #X connect 6 0 0 0; #X connect 9 0 10 0; #X connect 10 0 11 0; #X connect 11 0 8 0; #X connect 12 0 8 1;

Yet more DS GUI excursions
by Luke Iannini 23 Jan '09

23 Jan '09

Here's another experiment with datastructure-based GUI replacements. As with Chris (with his recent excellent "expanding GUI" concept), I'm a big big fan of hiding complexity, and I also like keeping details and interaction "in context", as in, somehow connected to or growing from the control you're manipulating. Apple's doing this tons lately, e.g., the new iLife http://blog.cocoia.com/2009/01/07/iwork-ilife-09-ui-roundup/ ("HUD panel changes" is the only pic I can find, but there are many more examples in the new iMovie videos @ http://www.apple.com/ilife/imovie/). So, this is a simple context-bubble sketch: dragging the slider reveals a bubble with two different interpretations of the slider's value. With the new "click" message, these could me more than transient datalayers, and could graduate to being actual interactive controls. The biggest problem with this example is that the bounding box of the GOP needs to be bigger than the control to give room for the context popup to appear, meaning every control has a giant black rectangular halo. It would be really awesome if there was a way to hide that box, just like IOhannes added the option to hide the object name and arguments. Another really nice addition to DS would be variable opacity, so when I do a filledpolygon I can specify 9005 as the color to get a transparent red rather than just 900. That would be of great use for both these context bubbles as well as, say, a sample range selection box where you can still see the sample data under the selection. And as ever, a way to specify a persistent z-index for DS is pretty essential for any complex use. Okee, that's all for the moment Best Luke

[PD-announce] xxxxx_temporary_structure CTM 2009 friday 23 january
by Derek Holzer 22 Jan '09

22 Jan '09

xxxxx_temporary_structure CTM 2009 opens tomorrow, Friday 23 January, with an open lab and actions/performances from several of the participants beginning at 19:30 and running until 22:00. The laboratory will continue to be public every day until 31 January from 12:00-22:00 daily. There will be similar actions completing the lab cycle on the final day, Saturday 31 January, at 19:00. LOCATION KUNSTRAUM KREUZBERG BETHANIEN Mariannenplatz 2 10997 Berlin-Kreuzberg Public transport: U8 > Kottbusser Tor S3, S4, S8, S9 > S-BHF Ostbahnhof 10 minutes walking distance from MAO. http://www.kunstraumkreuzberg.de/ ABOUT xxxxx_temporary_structure CTM 2009 Tracing a clear line of development from both xxxxx_workshops: [in]tolerance during CTM 2008 examining the material basis of technology and a series of life coding events in Norway and Germany, xxxxx hosts an experimental nine day structure widening the scope of construction and constructivism to embrace the social and economic structures of production and performance. Public interface is to be made explicit, inviting participation, visit and conversation. xxxxx temporary structure presents the expansion of both known and less familiar constructive procedures and apparatus, for example software (Pure Data, Python) and hardware (waves, circuits, simulation) into novel territory. Software becomes script and social pragmatics, hardware expands into optics, architecture, graffiti, elaborate kinetics and novel interfaces to the world addressing biologic and physical processes; a play of light, resonance and transmission. The relationship between structure and system is playfully opened, with the modelling of systems as core activity within the temporary lab space; simulation within both code and analogue electronics, the embedding of an internal observer allowing for a play with agents and agency. A concern with materiality and construction forms the base for an energetic examination of all manner of diagrams, public interface (reading space, discussion), bio-computing (plant life, EEG), world interface (practical endophysics), everyday technologies (light, food), code, transitions and translations. Such disciplines branch out mushroom like, revealing instabilities and new structures across nine days, in one space, publicly accessible throughout. xxxxx temporary structure is inherently experimental and interdisciplinary, inviting practitioners and artists who are well able to prise open the gaps between reified disciplines to actively create new social and constructive apparatus within the xxxxx space. A playful laboratory is proposed which does not mark boundaries between forms and between disciplines - which rather exposes and opens up social and artistic structures for sublime experience.
