la trente-cinquième rencontre du club d'utilisateurs de PureData de 
Montréal aura lieu à Vidéographe Production, 4550, rue Garnier (coin 
Mont-Royal) le samedi 22 mai 2010, de 13h00 à 17h00.

au programme :

1. la patch du projet Aether9
    presentée par Christiaan CRUZ et Audrey SAMSON

    Aether9 is developing a mobility contingent for its performances during 
a residency at Agence TOPO in Montréal. The aether9 collective has 
developed its own tool to stream remote performances from anywhere on the 
globe, which are concatenated and manifested on a web page (in combination 
with a live performance in front of an audience). This ability to stream 
audio/visual remotely has thus far depended on Max/MSP. During the 
residence two aether9 members have been writing and learning in Pure Data 
to create a PD patch that essentially captures webcam stream, manipulates 
the image and uploads it to a server. We propose to present our fumbling, 
our successes and frustrations with making this patch as well as how the 
project aether9 works.

2. Gem for data visualization
    by Peter LEE

    I will present preliminary work that uses GEM particle systems for data 
visualization in two projects, one a (possibly) scientific application, 
and the other for a theater performance. The first feeds data from a 
genetic study into GEM to visualize multiple variables associating at 
once. The second takes data generated live from biofeedback sensors to 
visualize physiologic signals of emotion. Both projects make use of the 
same interface for patching data to visualization parameters. The 
challenge is to find the mappings and scaling factors that enhance the 
viewer’s ability to detect differences in the data. I shall be interested 
in hearing ideas from the community on how to improve real-time rendering 
of particle systems to create images with greater nuance and expressivity.

3. Démonstration à choisir
    par Mathieu BOUCHARD

    Je vais donner une liste de mes nouvelles patchs de son, de vidéo,
    etc., et l'auditoire choisira parmi ces suggestions. J'improviserai
    alors deux courtes présentations.

     * prototype de jeu de Q*Bert.
     * prototype de jeu de Tic Tac Toe.
     * déformation temporelle des pixels sur un flux vidéo.
     * synthèse de cloches et de cordes sans oscillateur.
     * synthèse fait d'un filtre à pôle complexe et d'un gros rien.

4. Traduction
    (discussion de groupe)

    Ce sera une discussion informelle pour savoir qui est intéressé à
    participer à des efforts de traduction de la documentation de PureData.
    Nous parlerons de différentes sources de documentation et de diverses
    approches de traduction.

    Cette discussion a été proposée par Thomas-O. FREDERICKS, lequel sera
    absent ce samedi. Nous poursuivrons cette discussion lors d'une
    rencontre ultérieure.

5. temps libre
    (jusqu'à 17h00)
