by Eldad Tsabary 18 May '11

18 May '11

*Understanding**V**I**S**U**ALMusic 2011* *Hexagram-Concordia Centre for Research Creation in Media Arts and Technologies* *in collaboration with the Department of Music* *CONCORDIA UNIVERSITY* Montreal - Canada August 26th and 27th, 2011 ** CALL FOR PAPERS AND CREATIVE WORKS *_DESCRIPTION_* A two-day conference focused on developing an understanding of the practice of visual music, its definition, related creative and perceptual considerations, current trends, technological innovation, and possible future directions. The event will take place on *Friday the 26th and Saturday the 27th of August 2011* and will include paper sessions, roundtable discussions, and creative works presentations. We are inviting researchers to present studies that address visual music's multiple definitions and dimensions, questions around visual music aesthetics and meaning, hierarchy and correlation of sound and image in this context, and the audience's perception thereof. Artists are also invited to propose visual music presentations -- both live and fixed. Attendance is required in both cases. ** *_SUBMISSION PROCEDURES_* *Paper presentation*: please use the *online submission engine *at http://uvm2011.hexagram.ca/ to send: [1] an *abstract* (250 words or less)**and [2] a *short biography *ready for printing (250 words or less). Additionally send [3] *a 3-page CV as a PDF file *to uvm2011.concordia(a)gmail.com <mailto:uvm2011.concordia@gmail.com>. *Visual music presentation*: please use the *online submission engine *at http://uvm2011.hexagram.ca/ to send: [1] the title of your *piece, duration*, indication whether the presentation will be *live or fixed*, [2] a *short description* of the proposed piece (250 words or less), [3] a *short biography *ready for printing (250 words or less), and [4] *detailed technical needs*. Also include [5] *links to audiovisual sample material* hosted in a *non-expiring URL* (for this reason, please do not send your audio-visual material using /yousendit/ or any similar applications, and do NOT send your audio-visual material by email) and [6] send a *3-page CV as a PDF file* to uvm2011.concordia(a)gmail.com <mailto:uvm2011.concordia@gmail.com>. *_SESSION FORMATS_* *Paper presentations*: each paper will be presented in person by the author for approx. 20 minutes followed by 5-10 minutes of discussion. *Visual music presentations*: creative works presentations will take place in a visual music show that will conclude the colloquium and between paper sessions throughout the day. *Roundtable discussion[s]*: an hour-long open discussion on key issues related to the main theme of the colloquium. *_DATES_* - *Deadline *for reception of proposals: *June 18th, 2011* - *Notification* of acceptance: *June 30th, 2011* - *Confirmation of attendance* by artist/researchers: *July 20th, 2011* - *Colloquium* UVM2011: *August 26th-27th, 2011* *_UVM-2011 ORGANIZERS _* Ricardo Dal Farra (co-director) Eldad Tsabary (co-director) Luigi Allemano (collaborator) *_CONTACT, INFORMATION and ABSTRACTS:_* Email: uvm2011.concordia(a)gmail.com <mailto:uvm2011.concordia@gmail.com> UVM2011 website: http://uvm2011.hexagram.ca/ *Understanding**V**I**S**U**ALMusic 2011*

Re: [PD] four PS3 Eye on Mac Pro and Pd-ext and GEM
by news＠petervenus.de 18 May '11

Hello! i tried working with multiple ps3eye cams on OSX but did not succeed. it should work- maybe someone has a solution for that, i switched to linux in the end, where multiple cams of the same type aren't a problem at all :) maybe it works with osx when using multiple instances of pd...this was not an option for me. one thing you should take care of, at least, that is what i discovered: due to the bandwidth the cameras take, you can just run 2 cams on one USB2.0 controller at the same time, otherwise you will end up with a very jittered images. peter -----Ursprüngliche Nachricht----- Von: jack(a)rybn.org Gesendet: 18.05.2011 13:12:42 An: Pd-list(a)iem.at Betreff: [PD] four PS3 Eye on Mac Pro and Pd-ext and GEM Hello, I'm going to work on a Mac Pro with MacOsX.6.7 and the latest stable Pd-extended 0.42.5. I would like to connect four PS3 Eye on this computer and use GEM with pix_video to read these four devices in four instance of Pd (=> one camera per instance of pd). I will use Macam driver (or something else ?) Is it easy to get each camera working in the same time on this system ? Do you have experience in this area ? Thanx for help. ++ Jack _______________________________________________ Pd-list(a)iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list

We were hoping that the guy who did our particle system would do this, but he can't right now. Here's what Mitchel wrote to him. Zack and Mike thought you might know someone who could do this. Would you be oh so very kind and let me know? Thanks. Jordan Hi Reuben, After consulting with a PD expert, we're going to change your workplan slightly. Basically, you will not need to port your C++ code into PD Externals, as this might result in suboptimal CPU scheduling. Instead, you should use PD purely as an interface to control the particle system, which will be running in a different thread. The communication between the particle system and the PD interface should be done using Open Sound Control (OSC), which is an efficient UDP communication protocol. The idea is use OSC to send commands to the particle system (like changes in the parameters). This is fairly easy to do: you need to implement an OSC handler in your code that listens to incoming messages from the PD interface that you will design. I suggest you familiarize yourself with OSC before you get started on this ( http://opensoundcontrol.org/introduction-osc). Here is what our PD expert had to say: === So my suggestion for the particle system / Pd thing is: Don't make a pd external that contains an OpenGL rendering loop. It's suboptimal because you'll need a non-blocking polling and/or drawing mechanism. Pd expects to be in control of scheduling. If you draw GL in the same thread, you'll get blockage of DSP (clicky audio). If you draw GL in a separate thread, you'll need mutexes or condition variables to tell Pd when it's allowed to change the GL content (ie, between frames). This is tricky scheduling, and not necessary for what you're doing. A better solution is to provide an control interface via OpenSoundControl (OSC). ie, the particle system would be in a separate process with a socket that listens to control messages. You do a non-blocking poll of your sockets between frames. There are lots of libraries (eg, liblo or oscpack) that you can use for this. On the Pd side, I'd highly recommend using my [OSCrxtx] objects for sending messages:http://code.sat.qc.ca/pdsheefa/trunk/src/OSCrxtx/ _______________________________________________ Mumt_grad mailing list Mumt_grad(a)music.mcgill.ca http://music.mcgill.ca/mailman/listinfo/mumt_grad

P.s./off topic: I think you dont want to know how low is the minimum wage around here. Just open the news and you'll see how portugal is ina deep financial mess, somewhere in the line of what happened to greece or some other EU countries. I like that volunteer concept, seems fare.

Note that in practice, the check for reduced registration was quite lax, and as a result, very few people took full registration. I don't have figures of how many people paid full registration, how many people paid reduced registration, and how many people "volunteered" for 8 hours each instead. I know people who can answer those questions if it's good to know. BTW, 8 hours of "volunteering" in exchange of 50 $ fee equivalent is quite below minimum wage, which was 8,00 $ back then, I think (it's 9,65 $ now). BTW, 1 $ canadian was 0,69½ € back then, 0,72 € now. _______________________________________________________________________ | Mathieu Bouchard ---- t...

udpsend broadcast was Re: 0.43 should still be a test version

By the way, Though broadcasting does work with [udpsend], it only works with x.x.x.255 (where x.x.x is the address of the local network), but it does not work with 255.255.255.255. 2011/5/10 Martin <martin.peach(a)sympatico.ca>: >> I don't have any trouble with [udpsend] either.

hello, the latest build doesn't start, some changes in 0.43.1 seems to brake everything, I have to terminate pd from task manager, this happens on windows vista, I haven't tried to build this release yet. the 2011-04-30 release is still 0.43.0 and working good. -- Patrice Colet

hello, when starting several instances of pd-vanilla 0.43test3 it shows this message: Pd needs your machine to be configured with 'networking' turned on (see Pd's html doc for details.) this doesn't happen with pd-extended 0.43.0 -- Patrice Colet
