debugging Graph-On-Parent
by Hans-Christoph Steiner 18 Jan '10

18 Jan '10

Hey all, Since talking with Ico, Luke, Ed, and others it seems to me that fully debugging the GOP GUI stuff should be a big priority for the 0.42.5 release of Pd-extended. This would also fit in well with the wrapping up of pd-gui-rewrite. So for all you deep into GUIs with Pd, please report bugs and make example patches so we can get to the bottom of this. Ico's is a good example: .hc ---------------------------------------------------------------------------- News is what people want to keep hidden and everything else is publicity. - Bill Moyers

Hi list, here is a simple patch I'd like to share with you. If you print the attached .pdf and hold the patterns in front of the camera you can make interesting sounds.

pix_mulitblob and matrix
by olsen 05 Jan '10

05 Jan '10

hi thanks to IOhannes indications i'm feeding my pix_mulitblob output into the iemmatrix now. as long as there're enough blobs in the picture it works pretty nice. but as soon as there're less blobs than given in the argument to pix_multiblob i get: error: $43: argument number out of range error: $44: argument number out of range ... for all the arguments of undetected blobs. and as soon as there's no blob in the picture the pd-shell reports: matrix : corrupt matrix passed do i do something wrong? i was using the attached patch thanks for help & hints olsen -- ETs DNA will not be televised

msgfile doesn't print a full stop after a number..?
by James Dunn 02 Jan '10

02 Jan '10

Hi, I've noticed that that msgfile doesn't seem to print a full stop (period) after a number. I'm using Pd version 0.42.5-extended-20091228 on Ubuntu 9.10 and am sending the message [read filename.txt cr (. The console reports msgfile as "[msgfile] part of zexy-2.2.3 (compiled: Dec 28 2009)" Is this normal? For the time being, I've added a ¬ character after the number (which isn't printed) to enable the full stop to be printed. thanks James

using the same shader in multiple places
by Matteo Sisti Sette 01 Jan '10

01 Jan '10

Hi, Is it legal to load the same shader (i.e. the same .vert and .frag files) multiple times? I.e. have an abstraction with a [glsl_vertex], a [glsl_fragment] and a [glsl_program], and multiple instances of this abstraction? I ask this because I did this and pd crashes as soon as I open the gemwin. I had some trivial errors in the shader files before, and I got the compiler error messages without crashes, but then I corrected the error and now it crashes. Obviously there may be a lot of other reasons for the crash but I have to guess. Is there another way to use the same shader in multiple places? For example, I see [glsl_program] outputs an id in its right outlet: can I perhaps use that ID to use that shader elsewhere? If so, how? In this case, would each "instance" of the shader have its own value of "uniform" parameters? By the way, I should probably ask a more basic question: is it legal to have more than one [glsl_program]s (meaning a [glsl_vertex] a [glsl_fragment] and a [glsl_program]), no matter whether with the same or different shader programs, "under" the same [gemhead], provided that they are in different "subchains" with [separator]s? Thanks m. -- Matteo Sisti Sette matteosistisette(a)gmail.com http://www.matteosistisette.com

Re: [PD] select audio & midi from patch
by mark edward grimm 01 Jan '10

01 Jan '10

... continuing this thread: http://lists.puredata.info/pipermail/pd-list/2008-09/064895.html maybe there is a thread more recent than Mon Sep 8 04:06:35 CEST 2008 on this? Anyway.... I am on OSX pd-extended 10.6.2. The attached patch seems to work 'ok'. BUT for some reason 1) I have to bang the message twice to load the midi settings in the dialog box and 2) I have to click "apply" and/or "OK" for these setting to take effect. I would like to automatically change the settings when the patch is loaded without banging twice and hitting 'ok' in the properties menu.... sorry. but i couldn't find more recent documentation on this.... Cheers! mark

compiling pd vanilla problems on OS X 10.6 Snow Leopard
by Rich E 31 Dec '09

31 Dec '09

Hi, I am having problems compiling pd from Miller's website in OS X Snow Leopard. Basically, Pd fell behind Apple's updates. Here are my problems, fixes where I found them: - the configure script automatically adds -isysroot blah blah for the 10.4 sdk, which doesn't work. this line is removed. - the included portaudio (and more importantly, its coreaudio components) with pd does not match the coreaudio framework included with Snow Leopard. There are lots of deprecations and finally undeclared methods. I tried just updating the source code from that in portaudio's svn, but this led to further undefined calls that I don't remember. - using '-disable-portaudio' doesn't do any good because it is automatically added if you are on OS X (I wanted to just use jack since portaudio is outdated). - I had to remove all '-arch' flags except i386 to get everything linked. Okay, after that, it compiled. whew. Still, pd's gui will not run because libPdTcl.dylib either isn't found or is the wrong architecture, I still can't tell: $ pd -jack Error in startup script: dlopen(/usr/local/lib/pd/bin/../bin/libPdTcl.dylib, 10): no suitable image found. Did find: /usr/local/lib/pd/bin/../bin/libPdTcl.dylib: mach-o, but wrong architecture while executing "load $pd_guidir/bin/libPdTcl.dylib" invoked from within "if {$pd_nt == 2} { # turn on James Tittle II's fast drawing set tk::mac::useCGDrawing 1 # anti-alias all lines that need it set tk::mac::CGAnt..." (file "/usr/local/lib/pd/bin/pd.tk" line 67) ^CPd: signal 2 It is there, they are all i386 and tcl/tk are universal binaries, so I don't know. Anyone else? Running pd with no gui and jack works. regards, Rich

Re: [PD] A present
by Matteo Sisti Sette 31 Dec '09

31 Dec '09

Hi, I still don't understand the game, but I can only move the "snake" within a very small rectangle (or square) approximately at the center of the screen. It disappears on one side and appears on the other one, but of a small square, and it looks like it is supposed to do the same on the whole window, or is that the expected behaviour? It seems impossible to avoid the red circle while being constrained within a small rectangle, but maybe I'm missing something... Apart from that, I get the error "click~: couldn't create": is that an object of PD Extended, or an abstraction that is missing? Thank you for sharing the patch. I love games :) m. -- Matteo Sisti Sette matteosistisette(a)gmail.com http://www.matteosistisette.com

How to use /dev/video2 virtual video device in GEM
by Bart Koppe 29 Dec '09

29 Dec '09

Hi, I use /dev/video2 to get a mjpeg live stream into PD. With pix_video I can open my webcam, but when I open the virtual video device (/dev/video2) i get an error, i guess todo with the fact that it's not a real webcam: error: Cannot open '/dev/video2': 25, Inappropriate ioctl for device GL: invalid enumerant-- Is there other ways to get it fixed in GEM? With pdp_v4l i can open the virtual device, but I want to try it in GEM, mostly because GEM is better documented, I need to add several jpeg/png pictures on both sides of that stream. Thanks..
