attached is what i found in my archive from last year. sorry there is some pdmtl code in there it looks like. otherwise the camera_para.dat and patt.hiro have to sit at "/" looks like there was some "cube" code in there too... i never got a chance to get it going though. pd-extended 41.4 release on osx 10.6.2 im on BTW Thanks! m --- On Sat, 11/21/09, Martin Schied <crinimal(a)gmx.net> wrote: > From: Martin Schied <crinimal(a)gmx.net> > Subject: Re: [PD] pix_artoolkit example > To: mgrimm(a)syr.edu > Cc: "pd_list Listserve" <pd-list(a)iem.at> > Date: Saturday, November 21, 2009, 1:18 PM > mark edward grimm wrote: > > Hello, > > > > Been a while since I messed around with pix_artoolkit. > A student of mine is really interested and I wanted to give > her an example but I don't have time to write a patch.... > > > > Does anyone have an example that replaces the marker > with a 3d model and tracking it across the gem win? > Wow, that's good news - i never figured out how to get it > recognize a marker.

Gem movies size
by colet.patrice＠free.fr 21 Nov '09

21 Nov '09

Hello, a large format video that takes 5% cpu with quicktime is almost impossible to play on gem, because it takes more than 100%, like if Gem has problems with hardware accelerated video decoding, any hint?

Re: [PD] is there a way to get symbol length?
by Matt Barber 21 Nov '09

Here's a vanilla approach using the .n sprintf function of makefilename. Not completely tested...

noob: the next step?
by Andrew Faraday 20 Nov '09

20 Nov '09

Hey Guys >From a relative noob, I've started to get a bit stale on using PD. Tho I have done some work build around new objects I've found (e.g. a patch to react to [time] and [date] objects). Can anyone suggest objects to get me interested, particularly in generating/importing data or sound manipulation.

I go from song to song by closing the current patch and loading the next. I haven't abstracted the playlist functionality yet, but I have made the patch open and close abstraction ... [rc-openclose]. The playlist is basically just a wrapper for a [coll] object. Transitions are rough (may cause clicks/dropouts), if anyone has a way to do a smooth transition when opening and closing a patch while audio is playing, please let me know.

pduino digital read problems
by altern 20 Nov '09

20 Nov '09

hi i am doing this small example to read a digital sensor with pduino. i test it with an arduino program that reads pin 2 and writes it to pin 13 and this works fine, i get a LED light on and off with my infrared sensor. however when i try this very same setup in PD i dont get it to work. i am starting up arduino object to the right COM port, i can write manually to pin 13 and the LED flashes, but i dont get anything from pin 2. I have not used digital sensors for ages with PD so i dont remember the right way to set them up. I send this message to arduino pinMode 2 0 i also tried sending before digitalIns 1 but nothing comes from comport outlet. so i am not sure what i am doing wrong please help! enrike

midi-out problem in jack/alsa
by Raphael Raccuia 20 Nov '09

20 Nov '09

Hi, I'm new on the list, and working with PD from a couple of years... I'm on linux, Ubuntu Studio 9.10 and Fedora 10 / planet CCRMA I have some troubles on latest vanilla version in repos (0.41): All the midi-out objects do the same: no problem to set midi channel and CC or Note number, but for each value change, I get in jack: ALSA: connection graph change and the buttons in alsa-midi tab flash shortly... but 128 time if I push up a CC fader for example! Some precisions: -no problem with midi-in objects -happens in my two systems (US and CCRMA) (don't know in earlier version, maybe I didn't noticed) -other alsa clients doesn't make any problem -happens when PD is connected or not in alsa-midi -but only when pd dsp is on -same with alsa audio drivers or FFADO (firewire) -other person seems to have the same problem: http://puredata.hurleur.com/sujet-3479-midi-note-leads-connection-graph-cha… Something else: PD seems to eat a lot of CPU when connected with jack/FFADO (~25%), and very few with jack/alsa, even with DSP off!?! -I noticed some bugs (or will be enhancement?): when closing a patch (ctrl+w or mouse), dialog opens behind others (top of PD main)... When 10 (sub)patches are opened it's something boring... -when PD opens, it connects everything in jack, not just I/O, same in midi-connections... Maybe it's too much? Thank's for your help cheers r

Pd Scene Change?
by Pagano, Patrick 19 Nov '09

19 Nov '09

Hi Is there a way to make Pd behave similar to Isadora/SFX type products by having it "step" through different patches sequentially? Isadora uses "jumps" that are usually triggered by keyboard mappings, like space bar etc.. SFX uses a "GO" button which pretty much does the same thing stepping through CUEs when clicked. I would like to see if we could have 4 different pd patches and step through them with a keyboard or some external/HID input Has anyone done this already? I am assuming qlist, but I would love to see a working example before I try to reinvent the wheel. I have seen theatreMAX but that seemed more related to complex DMX lighting cues Thanks in advance pp
