Re: [PD] higher math
by Jonathan Wilkes 08 Sep '09

08 Sep '09

I made a bug report about this back in February: http://sourceforge.net/tracker/index.php?func=detail&aid=2583821&group_id=5… But I didn't address that [exp~] is missing a right inlet (or that the help file is wrong). So I just added that as a comment for this bug. -Jonathan --- On Tue, 9/8/09, Hans Roels <hans.roels(a)base.be> wrote: > From: Hans Roels <hans.roels(a)base.be> > Subject: [PD] higher math > To: pd-list(a)iem.at > Date: Tuesday, September 8, 2009, 11:29 AM > Hello, > > I noticed some strange behaviour of some higher math > objects in Pd vanilla (0.42-4): > 'log~' has a right inlet and according to the help file a > 'optional creation argument initializes right inlet (the > base of the logarithm)' but this doesn't work.

art installation using pd/pix_opencv/firmata
by olsen 08 Sep '09

08 Sep '09

buenas i wanted to let you know about an art installation i did recently. the installation is using pd pix_opencv and firmata on 2 ubuntu boxes - it's running since ~3 month 6 days a week so far almost flawlessly. a video can be found : http://www.vimeo.com/5836740 if anyone interested in or around zürich - the show is up until the 4. october at the museum of design in zürich. i would also like to thank pd-people for help & providing these nice pieces of software! thanks & greets olsen -- ETs DNA will not be televised

higher math
by Hans Roels 08 Sep '09

08 Sep '09

Hello, I noticed some strange behaviour of some higher math objects in Pd vanilla (0.42-4): 'log~' has a right inlet and according to the help file a 'optional creation argument initializes right inlet (the base of the logarithm)' but this doesn't work. If I create a 'log~ 10' object it still computes the logarithm base e; after I send a number 10 to its right inlet, it does. The same for 'pow~', the initialisation argument doesn't work. the 'exp~' help file talks about a right inlet but there is no right inlet (I guess this is a wrong help file...). The non-audio object 'log' doesn't have a right inlet, so changing the base is impossible? hans r

[pix_video] with v4l
by Miha Tomšič 08 Sep '09

08 Sep '09

Hello! On Linux using Gem 0.92 from SVN I am using [pix_video] with Logitech QuickCam 4000 and v4l driver but the red and blue colours are swapped. Is there a way to instruct [pix_video] to use different colorspace (BGR instead of RGB)? If not what is the cheapest way to convert from one colorspace to the other. How can I get any additional information from pix_video (framerate, resolution ...)? Thanks and take care, Miha

i'm sorry, you never reported that seriously, which plugin ? when ? at what time of the day? was the sun shining? there are many reason why a frei0r plugin crash, i don't get your point.

fft and store lists
by Andres Ferrari 08 Sep '09

08 Sep '09

hello, Is it possible (in pd of course) to capture the frequencies and amplitudes by fft and save to a text file?...like a sdif file "made in home" using fiddle is easy...but using fft objects i don't know how to do... any idea?...any suggestions? thanks a lot!!!

ola, after lots of useless discussions, let's get back to work... before the workshop that will take place in Baltan Labs, Eindhoven, from 21th to 17th of September, in collaboration with Piksel ( http://www.baltanlaboratories.org/?p=1038 ), we just released the version 0.2 of the OpenCV bindings for PD : pdp_opencv / pix_opencv. you can find the source code and compiling instructions there: http://www.hangar.org/wikis/lab/doku.php?id=start:puredata_opencv we would really appreciate dome people to beta-test it and report us the problems they encounter ( especially on osx which i don't use )...or the features they would like to add. saludos, sevy
