We *do not* want to do that yet. I’ve found that on TK 8.5, there are a number of issues that need to be addressed, including the object creation hot keys being triggered twice. I’ve been working on updating the build system so I can finally build Pd on new Mac OSXs (almost there) and then I’ll look into TK 8.5 support. Probably not in time for this release -------- Dan Wilcox @danomatika <https://twitter.com/danomatika> danomatika.com <http://danomatika.com/> robotcowboy.com <http://robotcowboy.com/> > On Apr 25, 2016, at 7:32 AM, pd-list-request(a)lists.iem.at wrote: > > From: "me.grimm" <megrimm(a)gmail.com <mailto:megrimm@gmail.com>> > Subject: Re: [PD] [PD-announce] pd 0.47-0 test 1 released > Date: April 25, 2016 at 6:56:43 AM MDT > To: pd_list Listserve <pd-list(a)iem.at <mailto:pd-list@iem.at>> > Cc: pd-announce <pd-announce(a)iem.at <mailto:pd-announce@iem.at>> > > > hi miller, > > any plan to update Tk from version 8.4 to 8.5 (osx)? > > thanks > m

pix_opencv shape recognition
by stéfan piat 26 Apr '16

26 Apr '16

hello, I try to figure out how to use [pix_opencv_matchshape] with [pix_opencv_contours]. (also [pix_opencv_knear]) but I don't really understand how to use them (from help patchs). this is to compare a bunch of preloaded images with shapes from a live video to trigger differents events maybe someone knows where to find some nice example patchs ? thanks stéfan

send message from Pd patch directly to tcl/tk
by David Kent 26 Apr '16

26 Apr '16

The Pd Vanilla 0.46-7 Windows distribution includes tcl/tk 8.5 and a widget demo. The demo can be opened with the message exec wish85.exe $::sys_libdir/lib/tk8.5/demos/widget pasted into the "tcl prompt:" + <enter> Initially I am trying to find a way to send a message directly to that prompt from a patch, in a similar manner to [; pd( That seems to have been expressly omitted from the console build. There is a widget editor available (vtcl) which makes widget building more accessible for noobs like myself. If an object or objects exist, or could be compiled for Pure Data, that could open a widget and receive variables from user interaction with that widget then a patch could call widgets in -nogui mode (or not) and present a simple user interface to a "user" of the patch. I have implemented (badly- but I am learning fast) an additional menu item for the Pd window which can communicate with tcl/tk (working for windows os) http://forum.pdpatchrepo.info/topic/9991/woof-a-new-window-menu-for-vanilla- tcl Please let me know if I am "breaking" the license, and of course I will stop. But for now I am stuck anyway. David. _____ No snowden found in this message. Checked by AVG - www.avg.com Version: 2016.0.7163 / Virus Database: 4563/12106 - Release Date: 04/26/16

Re: [PD] [PD-announce] pd 0.47-0 test 1 released
by Pierre Guillot 25 Apr '16

Hi, The clone is really great ! I think there is a bug, the two first copies seem to have the instance number 0. And if the first inlet in the abstraction is a signal inlet, you can't use it to pass message to the object (like vis). I think this is because the clone uses the flag "CLASS_NOINLET" but perhaps that even if the abstraction doesn't have any inlet, the clone object could have a minimum of 1 inlet (just to use the visible message). Anyway thanks !

[PD-announce] pd 0.47-0 test 1 released
by Miller Puckette 25 Apr '16

25 Apr '16

To Pd-announce: Pd version 0.47-0 test 1 is available on http://msp.ucsd.edu/software.htm or via git from sourceforge: git clone git://git.code.sf.net/p/pure-data/pure-data I'm still fixing bugs but the major changes are in place: a "clone" object for making voice banks etc., and a "zoom" feature for people whose high-resolution displays make Pd's windows microscopically small. (Also, setting the Pd window font size now extends to menus and dialogs). cheers Miller _______________________________________________ Pd-announce mailing list Pd-announce(a)lists.iem.at https://lists.puredata.info/listinfo/pd-announce

I don't know, I have a huge soft spot for [list-drip]. I think it's the paradigmatic example of how to do a recursive function in Pd (naive approaches to which usually die with a stack overflow). It makes sense to have a built-in iteration method for [list], but I'd kind of selfishly hate to obsolete [list-drip]. It's great for teaching because it makes students think a lot about how things are implemented. On Sun, Apr 24, 2016 at 7:49 AM, Christof Ressi <christof.ressi(a)gmx.at> wrote: > Thanks a lot!

Sample accurate (audio) triggering of vline~
by Wilfred de Zoete 25 Apr '16

25 Apr '16

In a complex waveshaping environment I'm using arrays as wave tables. There is one [phasor~] that runs the patch and I use [+~] to change phase of reading out the arrays. Now one of those arrays consists of only one pulse. I want to use that to trigger a [vline~] in sample-accurate time. But how can I use the pulse in the array as a trigger for [vline~]? I would prefer not to use [snapshot~] as it's not very accurate since that needs to be triggered itself by a metro and it isn't precize enough. The [phasor~] I'm using is constantly pitch changed, ranging from almost zero to 250 Hz max. The [vline~] has random ramp up, delay and ramp down, that's why I don't use an array to make an envelope. Cheers, Wilf

I am teaching two sessions of an Introduction to Pd workshop in Cairo for people with no prior experience at this event: http://www.cairotronica.com/ The workshops will be May 5 and May 6 from 5:00-8:00 PM. I will also have a project in the exhibition that was created, in part,with Pd and will give a lecture about it.

Dear list, did anyone try to compile GEM on the RPi 3 with activated OpenGL on it? I am curious if it can handle 3D graphics with the [model] object and lights. Best: Popesz

GEM blurring
by jma＠jeanmarie-adrien.net 22 Apr '16

22 Apr '16

Hello list I need to blur a little portion of an animated image with GEM to achieve dynamically a good visual continuity between foreground and background : means blurring the edge between foreground and background. This edge is not moving in the frame, just the content of the background varies. What would be the object(s) for doing this ? tks a lot JM
