Computer Vision is currently acquiring a growing relevance in the field of
interactive arts. From Myron Krueger’s pioneering artwork in the 1970s to the
present day, many artists have used Computer Vision techniques in their works,
extending its field of traditional applications (medical, military, industrial,
etc.) to interactive artistic practices. It might be visible in an interactive
installation or hidden/embedded when used, for example, in gesture-driven
musical instruments.
The purpose of this workshop is to introduce some computer vision techniques
that form the basis of the actual OpenCV library for Pure Data; a set of
objects, utilities and examples to use those techniques in an Open Source /
FLOSS environment for one the very first times. At the same time we will
introduce some practical examples of possible use cases of this technology,
working on thematic research in the different domains of application:
Interactive Installation, Augmented Reality, Learning Interfaces, Interactive
Instruments, etc. This list will be extended depending on the interest and
focus of the participants.
This workshop forms part of a collaboration between BALTAN Laboratories and
Piksel. As part of BALTAN’s Blueprint research programme investigating the
roles and forms of the art and technology laboratory of the future, BALTAN and
Piksel are collaborating to explore the relationship between hard and software
developers working on free and open source tools for artistic production, and
the artistic use and development of these tools in a laboratory setting. The
workshop is both open to the public as well as part of a collaborative
research residency (for which we now have an open call).
Participation in the workshop is flexible. Days 1-4 involve acquiring basic
knowledge and set the groundwork for working further with the technology. Days
5-7 will be dedicated to group work on specific projects. All participants are
required to join the workshop on days 1 and 2 for the basic theory and
practice. Attendance for the remaining days of the workshop is flexible but
participants are asked to indicate when registering what days they will
definitely be present.
To register: please send an email with your bio, technical experience and a
short motivation indicating why you would like to join the workshop to
angela[AT]baltanlaboratories.org. Please also be sure to indicate the days you
intend to be present during the workshop week.
Note: Participants are asked to bring their own machine and video devices. All
machines will be configured so that participants will be able to keep working
on their project after the end of the workshop.
We will configure the machines as needed by OpenCV :
ppc mac-intoshes : apple’s osx with gem
intel mac-intoshes : apple’s osx with gem
or ubuntu with pdp/pidip and gem
pc’s : ubuntu with pdp/pidip and gem

Hi all,
I've updated the metastudio packages with the old svf~ external in the drumsynths (clinok~, clinoker~ and fmf_perc~) and svf_fl~.
The bsaylor/svf~ external has problems - denormals cause the filter to max out the CPU and will crash any patch mid-preformance. I also found this problem with moog~ (in moog_fl~) so watch out for it crashing your patch! If it does, I recommend switching to svf_fl~ for a dynamic filter.
This is a critical update, so if you're using metastudio then head over to
http://sharktracks.co.uk/puredata
And save yourself some future embarrassment!
Enjoy!
Ed
Hi All,
I finally finished the help file for trigseq.pd, so there is an updated version of metastudio 3 for download at
http://sharktracks.co.uk/puredata/metastudio-0.3.zip
By the way, it runs much better if pd is not in -rt mode. An rt metastudio will be available once I've finished making nogui versions of all the objects. Modpatch is still a little flakey - for the next update. Watch this space!
I've split it off from the metaVJ:

enjoy!

= Create reactive music scenes with the RjDj composer pack =
July 24th, 2009
http://more.rjdj.me/2009/07/24/composerpack/
For some time now the RjDj team has been hard at work creating a
library of tools to help everyone create scenes for RjDj (i.e. Pd patch
bundles). These have been available for a while, as RjLib, from the
RjDj website and wiki. However we have now consolidated these tools,
in addition to some others, into the RjDj composer pack.
It's available for download now here :
http://trac.rjdj.me/wiki/ComposersPack
The RjDj composer pack is a set of tools designed to help at all
stages of the scene creation process. It contains a series of folders:
1. Example Scenes - This is a series of examples for RjDj to
get you inspired.
2. Scene Template - This is a blank template for you to use to create
scenes. It contains temporary images in the correct size and also
contains the "rj" library in a subfolder. The rj library contains a
large number of Pure Data abstractions (vanilla!) we have developed which you can use
whilst creating your scenes. It features many types of tools you would
find in conventional music making, as well as many you certainly
wouldn't!
3. Rjutils - This folder contains a number of Pure Data tools for
working with scenes. They are useful for testing scenes whilst on your
computer.
4. Pd - This folder contains some essential custom Pd objects that are
not part of the usual Pd installations. You should add these to the Pd
installation on your computer (i.e. copy them to the 'extra' directory
or somewhere else in you Pd search path), but don't put these into
your Scene directory, as the RjDj mobile app includes them already.
6. Rjz server - This is a tool that lets you test your scene on your
iPhone or iPod Touch without jail-breaking it.
7. Doc - In this folder we are delighted to include, with kind
permission from Andy Farnell and his publisher, an excerpt from his
book "Designing Sound" which is an excellent introduction to Pure
Data.
Eventually we hope to incorporate a distribution of Pure Data within
the Composer Pack. In the meantime, please download Pd for your
platform here : http://crca.ucsd.edu/~msp/software.html rsp.
http://puredata.info/downloads (don't use Pd-extended, get the
'vanilla' versions on the bottom of the latter page.)
We are going to be continually updating this pack with new tools and
extended documentation and we have some very exciting things in the
pipeline for the composer community.

RjDj turns 1.000.000 and 100.000
July 23rd, 2009
http://more.rjdj.me/2009/07/23/1-000-000-and-100-000/
Wow. We just realized that RjDj passed two magic numbers!! RjDj Artists,
Producer, Fans, Freaks, Listeners, Team, Evangelist, Everyone get yourself a
drink and toast to the fact that we now have more than 100.000 scenes
downloaded through the RjDj app which also means that we have officially
surpassed more than 1.000.000 (ONE MILLION) distributed RjDj scenes.
About one year ago we started to do some hacking with a very, very small team
to prove the fact that reactive music is here to stay. In october 10, 2008 we
released the first version of RjDj and now, not even one year later we have
more than one million scenes out there. For the whole team here in RjDj land
this is a huge success. We are so proud about this that the first thing we did
is called our mum and dad to say thanks.
As RjDj scenes technically are Pd (vanilla) patches bundled with additional
resources this is big news for the Pd community. Who would have thought that
there will be one million Pd patches distributed to mobile phones within one
year? So the hugestest THANK YOU goes out to all the Pd patchers out there, to
the hackers attendig the Brazil Convention, that we sadly have to miss due to
bad timing on our side, and of course to Miller Puckette, without whom all this
wouldn't have been started the way it did.
This all really proves that releasing music as software is a very, very
powerful concept. We all have just started to grasp the potential of this and
let me tell you we are really busy pushing the boundaries. We will keep pushing
updates and new features and i hope we will also see amazing new scenes
released on RjDj during the next couple of month. Thanks again to all the
artists, producers, dj's and hackers releasing scenes on RjDj. And of course
thanks to all the listeners, who have managed not only to install a lot of
scenes but also to send us those 20.000 recordings. To celebrate, we just
switched one of the newest scenes from the kids on dsp to free. Go and get it :-)

For those wishing to consult the site of the previous convention, I have
the regret to announce that the name has been usurped by domain-snatchers,
and I have the pleasure to announce that we have a new name for it:
http://pure-data.artengine.ca/fr/http://pure-data.artengine.ca/en/
This is actually a copy of the old site, not just a new domain entry, so,
if you find anything that doesn't work anymore and that should, please
contact me.

I think they'll let non-Columbia people in if you ask nicely. Also,
if you have other NYC university IDs, they'll probably let you in
without a special pass. My NYU ID worked, for example.
