Help with OSX App minefield
by Jonathan Wilkes 06 Nov '13

06 Nov '13

Hello, I'm hoping some MacOSX gurus can help me traverse this mine-field. What I'm trying to do: Port Pd-l2ork (quick-and-dirty) to MacOSX in the form of a Pd-l2ork.app Minefields: * Pd-l2ork uses tkpath, which is built to work with Carbon and not Cocoa. So I must use tcl/tk Framework that uses Carbon instead of Cocoa. That should be ok because Pd-extended.app is currently set up to use Carbon. * Pd-l2ork uses the old pd.tk framework instead of the newer stuff from the gui-rewrite What I've done so far: * updated the configure file successfully * made a workaround for statbuf from stat.h not existing on OSX (in s_main.c) * made a workaround for RTLD not existing after ./configure and trying to make (s_loader.c) * successfully compiled Pd-l2ork * checked that tkpath actually works on OSX. It seems to work, using tcl/tk w/Carbon instead of Cocoa. * used otool and install_name_tool to change libPdTcl.dylib libraries to point at the App's Framework directory instead of system directories * changed AppMain.tcl to launch pd.tk instead of pd-gui (which it does successfully) What crashes so far: * inside pd.tk, I'm trying to do this: load $pd_guidir/bin/libPdTcl.dylib It finds the dylib fine but then it crashes, with the crash report referencing the first line of the following function of t_tkcmd.c in the backtrace: int Pdtcl_Init(Tcl_Interp *interp) { const char *argv = Tcl_GetVar(interp, "argv", 0); *** Any ideas where to begin to debug this? Is there some code I can add to Pdtcl_Init to print out some info I can use to tell where it's going wrong? I put the full error log here: http://pastebin.com/duHdRrsY Any suggestions appreciated. -Jonathan

strategy to apply shaders/motion blur to pmpd in a 1900x800 rectangular gemwin
by Marco Donnarumma 05 Nov '13

05 Nov '13

Hi all, I have a 1900 x 800 gemwin. I render a few geos on a big [sphere] and a pmpd system on top of it. I'd need some cpu-friendly motion blur and glow effects on everything rendered in the gemwin. My strategy so far has been to split the final rendering into two 800x800 squares. That is: I have two [snap2tex] snapping two separate [gemwin -1] onto two [square]. One [snap2tex] has 0 0 offset, and the other has 800 0 offset. Then, by modulating the opacity of [colorRGB] for the 2 squares I can get motion blur effect. This works fine, but the same splitting strategy doesn't work for shaders. If I apply a shader to the two [square] the coordinate of the texture are all mixed up. Also, when applying the shaders the cpu go up +30%, whereas [snap2 tex] takes way less resources. is that normal? What's the best way to go here? thanks! best, -- Marco Donnarumma New Media + Sonic Arts Practitioner, Performer, Teacher, Director. Embodied Audio-Visual Interaction Research Team.

There is already libpd and I don't see a bunch of elegant and efficient Pd frontends sprouting up because of that. (Though I'm sure there are a lot of projects that do cool things with it.) The main reason for this is that we haven't pulled out the gui elements yet. There isn't yet an interface in libpd to edit the object graph and I'm not sure where the plans are on that. Once it's there I'm sure we could see some interesting things. I imagine I could add patch editing to PdParty using Objective-C in about a week or two if I had such an interface. I agree with both Han's point that a long term goal of cleanly separating the gui from the dsp is what we want. At the same time, I agree with Jonathan in that we shouldn't abandon/neglect what's already here and working. The overall plan, as far as I know, is once there is a clean separation the dsp core from the gui, the pd tcl/tk app would then be updated to use libpd. As for when that would happen, who knows? Anyone want to hire Jonathan, Hans, me, etc at a research lab to do it? I'll be available in the spring :D -------- Dan Wilcox @danomatika danomatika.com robotcowboy.com

Japanese PD books
by Pagano, Patrick 03 Nov '13

03 Nov '13

Hello I was browsing on Amazon and I found quite a few books in Japanese written about pure data. I am wondering if there are any translations of these out there? I am currently reading the multimedia programming with pd and it seems nice so far but I am hoping and wondering if there is a more GEM focused book out there? Also, I wanted to pose/ask this question again regarding sequential patch playback. Peter and Marian's extended view toolkit kind of do this a little bit but I am wondering again if there is any way to configure or program pd to play a patch and then transition to another patch so that pd may be used for theatrical performances. I currently use Isadora for this but I still wish I could use pd for this purpose. I have fashioned playlist- but i would love to go from one Gem scene to the next with timed fades. I kind of can achieve to with pd & syphon on Mac but my main theatre computer right now is a windows box. Does anyone share this desire with me?

[path] external
by Ivica Ico Bukvic 02 Nov '13

02 Nov '13

Does anyone know where is the [path] external's source located (the one that has a help file in 5.reference/path-help.pd)? The PD_META suggests it is an internal object but I could not find any trace of a gensym("path") in the source (or in the externals folder for that matter). Any help that can resolve this mystery is greatly appreciated! -- Ivica Ico Bukvic, D.M.A Composition, Music Technology Director, DISIS Interactive Sound & Intermedia Studio Director, L2Ork Linux Laptop Orchestra Head, ICAT IMPACT Studio Virginia Tech Department of Music Blacksburg, VA 24061-0240 (540) 231-6139 (540) 231-5034 (fax) disis.music.vt.edu l2ork.music.vt.edu ico.bukvic.net

[PD-announce] DMT - Donnarumma, Michalakos, Tanaka tonight at Watermans Digital Weekender
by Marco Donnarumma 02 Nov '13

02 Nov '13

apologies for x-post ~~~ DMT live ~~~ FREE TONIGHT, Saturday 2 Nov, Bar 19.00 Watermans Arts Center, Downstairs Bar Brentford, London DMT is Marco Donnarumma, Christos Michalakos, and Atau Tanaka, a trio of visceral electronic musicians that interface corporeal gesture and physical gesture with pulsing electronic noise. Donnarumma plays the Xth Sense biophysical muscle sensor system to sonify the performer's body. Tanaka runs granular synthesis algorithms on the iPhone, and Michalakos plays the Augmented Drum-Kit, a bespoke electroacoustic instrument based on the acoustic drum-kit. Together they create a wall of sound that is live technological thrill. http://www.watermans.org.uk/exhibitions/exhibitions/digital-art--performanc… Hope to see some of you there, -- Marco Donnarumma New Media + Sonic Arts Practitioner, Performer, Teacher, Director.
