multiblob tracking in Gem while objects keep their IDs
by Max 16 Jun '13

16 Jun '13

hi list, a student of mine, Jakob Gomoll, did solve how to track multiple blobs while every blob keeps its ID. Here is where i scratch my head: It works fine until you render the output of the multiblob tracker to a rectangle. I'd like to understand why this is. Is it a bug or a feature? connect the tracker to the pix_texture (where the red line is) and it will mess up the result:

[PD-announce] library template v1.0.14 released!
by Hans-Christoph Steiner 15 Jun '13

15 Jun '13

I just posted v1.0.14 of the Library Template that fixes some build issues on recent Mac OS X and Android: https://puredata.info/downloads/template If you are starting a library or want to port your existing library to multiple platforms, then the Library Template will make things much easier for you. Libraries in this format are very easy to install and they integrate tightly with Pd, providing things like namespace support, meta data for the search function, a listing in the Help Browser, etc. It handles building on all supported platforms (currently GNU/Linux, GNU/Hurd, GNU/kFreeBSD, Mac OS X/Universal, Windows/MinGW, Windows/Cygwin, Android, Apple iOS). Using this template makes it trivially easy to package your library for Debian, Ubuntu, Fedora, Gentoo, etc. Find out all about it here: https://puredata.info/docs/developer/LibraryTemplate .hc _______________________________________________ Pd-announce mailing list Pd-announce(a)iem.at http://lists.puredata.info/listinfo/pd-announce

"pd: exiting" on RPi running arch
by James Dunn 15 Jun '13

15 Jun '13

Hi, I have installed Arch linux on my Raspberry Pi and am logging in with ssh -Y raspberrypi.local. I can run xterm fine over the connection but pd fails with no information other than: $ pd priority 6 scheduling enabled. priority 8 scheduling enabled. watchdog: signaling pd... pd: exiting If I set the debug level to 5 I get the following information: $ pd -d 5 set pd_whichmidiapi 2 priority 6 scheduling enabled. priority 8 scheduling enabled. pdtk_watchdog set ::tmp_path {} set ::sys_searchpath $::tmp_path set ::tmp_path {} lappend ::tmp_path {/home/james/pd-externals} lappend ::tmp_path {/usr/local/lib/pd-externals} lappend ::tmp_path {/usr/lib/pd/extra} set ::sys_staticpath $::tmp_path set ::startup_flags {} set ::startup_libraries {} pdtk_pd_startup 0 43 4 {} { {OSS 2} {ALSA 1} {jack 5} } { {default-MIDI 2} {ALSA-MIDI 1} } {DejaVu Sans Mono} bold set pd_whichmidiapi 2 pd: exiting Any ideas why pd can't run over the ssh connection? It runs fine with the -nogui option. James

Fwd: Sensors GPIO Raspberry Pi Pd
by Julian Brooks 05 Jun '13

Message resent for thread archives with smaller picture size. Julian ---------- Forwarded message ---------- From: Julian Brooks <jbeezez(a)gmail.com> Date: 11 April 2013 19:24 Subject: Re: [PD] Sensors GPIO Raspberry Pi Pd To: Martin Peach <martin.peach(a)sympatico.ca> Cc: PD List <pd-list(a)iem.at> Hey Martin / list, Finally got all the stuff and ... It’s not working! We spent the day soldering cables and connecting stuff up as per the Omron ‘App Note 01’ spec sheet. Started off super-conservative using the I2C level converter (case 3 page 4) http://www.adafruit.com/products/757#Blog/Flickr We tried resistors on both sides (being super paranoid!) and then we took the low (Pi) side ones off. We then moved on to case 2 page 3 of this same document… At each stage we checked with “I2Cdetect –Y 1” and nothing was visible. The grid shows no attached devices every time we run it. We re-booted at every stage following the various online tutorials/methods of setting up I2C GPIO on the Pi (checked & double checked). As you can see we’re using a pi protoplate: https://www.adafruit.com/products/801 In the photo I’ve attached the cables are coded as follows: Orange GND Yellow 5v Blue SCL Green SDA The white is also 5v for the pull up resistors. The resistor values are 4.7k btw. We have tested the cable that terminates at the sensor and all that is OK. I put a multimeter on the GND and SDA solder points on the sensor itself and got 3.7v… I put a multimeter on the GND and SCL solder points on the sensor itself and got 0.0v… Don’t know if this means anything or could be useful to know! Stuck and frustrated now but hey, 3 weeks ago I knew absolutely bugger all about any of this and now I do (sort of). I'm thinking we could do with the most basic i2c sensor we can find as we have nothing to compare. Tonight I'm going to d/l a fresh raspbian and start from scratch to check that end. Feel like if we can't get past the 'i2c-tools' tests we're screwed - never mind getting it in and out of Pd. Any thoughts/pointers/options from anyone will be really appreciated? Cheers, Julian

linux best for pd? / "best linux" for Pd? / On a Mac?
by Alexandre Torres Porres 04 Jun '13

04 Jun '13

Hi there, correct me if I'm wrong, but it seems Pd runs smoother in Linux than in any other OS, is that right? Perhaps some of you have run benchmarks for it with the same machine and diferente Operational Systems. I was curious to try myself. Now, is there a "best linux" for Pd? Maybe one that allows you to tweak in a little more to have insanely low latencies? Yeah, the whole point and interest is to try and reach an absurdly optimized latency and CPU load. Now that I got myself a Raspberry Pi (my first linux) I wanna enjoy the opportunity/motivation to broaden my linux usage to my regular laptops. I use macs by the way. Don't know if that is an issue. Like being next to an impossible task to install a nice hardcore ("the best one") linux distribution in it. I've seen that recently Linux has been able to work (poorly at least) with Thunderbolt. I have an RME Multiface that seems to works well on linux. Since newer macbooks lost the PCI slot, all that I'm missing is that my thunderbolt to PCI slot adapter works in Linux. That'd be cool, to run it on my macbook air, on linux... but I digress. Thanks Cheers

first exercise with data structures
by Roman Haefeli 03 Jun '13

03 Jun '13

Hi all Finally an attempt to dive into data structures. I read Frank Barknecht's still excellent DS tutorial and, of course, section 4 of Pd's help written by Miller Puckette, which is a bit more demanding, but definitely very interesting. Though I can somewhat follow the simpler example patches, the fundamental concepts are still a bit nebulous. Here's my problem. I found how to use [filledpolygon] to draw a rectangle whose width can be changed by mouse interaction. When using the same [struct] as the element of an array, I can draw many rectangles which can be grabbed and moved by the mouse (x-y-array). However, when it is used as an element, the ability to change the width dynamically with the mouse is lost. When it is not part of an array, it cannot be moved easily (without going into edit mode). How can I have both at the same time? Is it even possible at all? Attached is an example that illustrates both cases. Roman

cool, so it seems I dont need to bother with "hardcore configuring" using a "not so easy one" like slackware? I'll give this Shumamis a try, but I don't see ardour there though.

ANN: New Pd-L2Ork x86_64 and Raspberry Pi release now available together with comprehensive how-to
by Ivica Ico Bukvic 31 May '13

31 May '13

It is my great pleasure to announce immediate availability of the latest Pd-L2Ork, its K12 module, as well as the inaugural official version of Pd-L2Ork for the Raspberry Pi platform. The new release is accompanied by a comprehensive documentation on how to connect RPi to the computer as well as run and configure Pd-L2Ork (and its K12 module) for operation on RPi. In addition, as part of this release, the regular Pd-L2Ork install instructions have been also streamlined to make them easier to navigate. Special thanks to NewBlankets Inc. for the Satchmo SuitSup Award that made our RPi hacking efforts possible! For more info visit: http://l2ork.music.vt.edu/main/?page_id=56 (x86_64 version with updated how-to) http://l2ork.music.vt.edu/main/?page_id=2288 (Raspberry Pi version download and how-to) Changelog highlights: *Fixed bug http://sourceforge.net/tracker/index.php?func=detail&aid=2457992&group_id=55 736&atid=478070; hopefully also fixed incorrectly reported hit/selection boxes for nested structs (like the one reported in the previous bug report) *added ability for preset_hub to write/read presets or entire scenes from files. Improved documentation to reflect new additions and to improve existing. *added multi-connect option with 5 different modes: 1. shift-click manual multi-connect 2. two selected objects multiple outlets to multiple inlets 3. two or more selected objects connecting to one unselected one 4. one unselected connecting to multiple selected ones 5. multiple selected ones connecting to one's multiple inlets OR the other way around (determined on whichever mode gives more valid connections) Option 1 requires use of shift. Other options are based on what is selected at the time of making the first connection (others are automatically created based on conditions). Later consider adding special undo that undos all connections in one step, rather than multiple steps. For more info, please see Jonathan's recent email on the pd-list: http://lists.puredata.info/pipermail/pd-list/2013-05/102871.html *added ability for gop to intelligently detect when iemgui objects fit (or don't) inside gop window. the same also applies to dynamic changes to iemgui properties (size, font, label, delta, position, etc.) *selection box makes patch scroll when reaching patch window edge *Added support for multiline comments (with some help from Taylor O'Connor and Jean-Philippe Ouellet). *disis_wiimote 1.0.4 *added raspbian compile option *improved logic for freeing rtext that alleviates memory leak but also does not crash abstractions and gop objects (there are still memory leaks apparent in l2ork_output~ external which may be linked to individual objects having incomplete free functions). See http://sourceforge.net/tracker/?func=detail&aid=3605235&group_id=55736&atid= 478070 for more info *Fixed segfault bugs with ascseq and ascwave externals *fixed memory leak (see https://sourceforge.net/tracker/?func=detail&aid=3605235&group_id=55736&atid =478070) *bug fix http://sourceforge.net/tracker/?func=detail&aid=3605973&group_id=55736&atid= 478072 Complete changelog (without the highlights): *backported tcl updates to properly support updated pddplink *fixed segfault when closing array window/subpatch due to lack of checking of valid resize/move hook pointers *added example files for the expanded preset_hub documentation *fixed accelerated displace bug where nested structs did not get properly tagged/selected *fixed erroneous meta file generation script *numerous bug-fixes for mouse down/up and key press combos (e.g. shift-clicks for multiconnect and dragging within an object) *added accelerated displace to pddplink *Made pddplink color match pd-l2ork *cosmetic improvements to Scope~ and coll *improved nlet highlighting (integrated it into glist), fixed bug with multiselect with mixed objects (accelerated and legacy) *improved scrollbar color selection *reintroduced cleaned up version of tooltip arrows *cord inspector is hidden during font scaling *improved font scaling and made cord inspector appearance consistent with tooltips *improved font scaling for size 24 *fixed consistency check error for magicGlass (regression) *fixed k12 shortcuts where secondary menu did not invoke k12 mode *minor fixes to the K12 library *added automatic resize of arrays when adding/removing points via ctrl+click, fixed a bug where array is not properly redrawn after a new point is created *made sure that properties windows associated with a patcher that is being closed are also closed at that time. *added an article to the NaN error report text *improved pow logic to accept negative numbers and deal correctly with NaN situations *added proper getrect support for comment objects *made drag scrolling less cpu hungry and easier to control *cords in front after iemgui properties apply *more scrolling improvements *lowered rate of getscroll when pasting to minimize cpu overhead *fixed random shifting of scroll when duplicating an object *proper fix for the crash when closing one of the many concurrently open root patches *automated installer clean-up for flext *remaining clean-up and flext integration in the intel/rpi build process *dependencies update *updated postlude *improved shortcuts so that pd-l2ork auto-creates midi ports on start-up *support for flext and auto-building of fluid~ and disis_munger~ *fixed bug where select all did not work with Console window focused *fixed regression where windows were not properly raised *improved window placement logic of new pd windows *improvements to disis_wiimote to provide unsuccessful attempt at connecting with an explicit 0 from the connect outlet (version bump to 1.0.4) *fixed stray bugs that were introduced with drawsymbol and resizable fonts and made drawnumber font resizable as well *made drawsymbol a distinct object that properly opens its help file and also supports resizable fonts *added input highlighting ability like that of iemgui's number2 to gatom class *fixed text not getting displaced properly while dragging a scalar (due to incomplete accelerated displace implementation) *fixed segfault due to delayed freeing of bindlists (necessary to prevent a segfault for dynamically changed sends/receives) *improvements to the incremental install script *new/improved icons *fixed typo for the new -r option (RPi build) *Improvements to the disconnection logic to the disis_wiimote *made shortcuts more flexible in terms of startup (not forcing JACK, which will help on setups that don't want/need JACK backend), as well as providing intelligent menu shortcuts for ALSA and JACK *made disis_wiimote statically linked so that new installs do not require install of the custom cwiid library that potentially clashes with other deb-based versions. *fixed regression from IOhannes' proposed fix (see e7acc4796b655100b650f898bb10687fb9f7355d commit) that affects propagation of scalar pointers through the trigger object. Use scalar-help.pd to test. *hopefully improved libglew support due to unfortunately named libs that limit their flexible rollout across different versions of Ubuntu (and likely other distros as well) *hopefully fixed stray iemgui dialog error when returning from the custom color selection dialog *removed unnecessary canvas_vis consistency check *fixed erroneous undo behavior after cutting two objects in a row *updated moonlib to the latest version and made changes to mknob.c to support accelerated displacing with tag *fixed midi dialogs *added ability for select object to recognize bang events *improved IO Error button on/off handling *refinements to the memory leak fix that avoid tripping consistency check in the findrtext *further refined trigger mechanism to offer ability to convert anything->symbol *implemented improvement for empty lists as suggested by IOhannes http://lists.puredata.info/pipermail/pd-list/2013-02/101518.html *fixed remaining memory leaks when instantiating/deleting abstractions (see previous commit). *minor adjustments to the binary script-based installer for the pd~ external support. *fixed bug where pd-l2ork symlink for pd~ external did not get installed Best wishes, 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 Dept. of Music - 0240 Blacksburg, VA 24061 (540) 231-6139 (540) 231-5034 (fax) ico(a)vt.edu http://www.music.vt.edu/faculty/bukvic/
