[PD-announce] Pd installation in Yamaguchi Japan
by michael fowler 22 Sep '08

22 Sep '08

The Akiyoshidai International Art Village (AIAV) will be hosting a performance/installation built with Pd based on a local Japanese garden, Sesshutei. A performance will take place on Sep. 25th, 6:30pm on the grounds of the AIAV and includes a collaboration with Yokohama audio firm and speaker manufacturer Taguchi (http://www.taguchi-mk.com/english/TopPage.html). The 8-channel installation is based on soundscape recordings collected from Sesshutei garden and uses the unique spatial predilections of the original garden as model for the sound diffusion. Composed and conceived by Australian artist Michael Fowler, the work also seeks to present the idea of the Otoniwashi (sound gardener) as a auditory manifestation of the Niwashi (Japanese garden designer). Details can be found in Japanese and English at: http://www.aiav.jp/programs/2008/michael_soundperform/ _________________________________________________________________ See how Windows connects the people, information, and fun that are part of your life. http://clk.atdmt.com/MRT/go/msnnkwxp1020093175mrt/direct/01/ _______________________________________________ Pd-announce mailing list Pd-announce(a)iem.at http://lists.puredata.info/listinfo/pd-announce

Gem video examples change my capture card settings
by eccn 21 Sep '08

21 Sep '08

(Hope this doesn't duplicate -- didn't seem to get posted) I just discovered pd-extended, and am now playing with live video via a PCI capture card. Very happy! But can anyone tell me why running any of the Gem video examples seems to change my video capture card's mode to some non-PAL setting? (My camera is PAL). Can I specify this as a default setting somehow? The OS here is Linux Ubuntu Studio (Hardy). I have a generic BT878-based tuner/capture card, which reports as follows after typing 'lspci': 00:0e.0 Multimedia video controller: Brooktree Corporation Bt878 Video Capture (rev 02) 00:0e.1 Multimedia controller: Brooktree Corporation Bt878 Audio Capture (rev 02) Many thanks in advance.

how pd refers to abstractions under OS X - example of "adsr" in vanilla version
by Lao Yu 21 Sep '08

21 Sep '08

Hi, I copied all of the examples out of the application package into another disk. everything is working fine. However when I was fiddling around I realized that pd would only open abstractions if they are exactly inside the folder that they were. For instance, the patch / 3.audio.examples/D02.adsr.pd would not work if it is opened from a different folder. I do not understand that. I'm not talking about an experimental patch that has stuff changed, the same patch just "saved as" doesn't work. I'd appreciate any advice. I tried to add the folder inside the application package to the startup path, but for some reasons that I don't understand the configuration is not updated (and I don't know if that would solve the problem in the first place). Best Jurgen

live input with GEM on OSX 10.5
by Orm Finnendahl 20 Sep '08

20 Sep '08

Hi all, is anybody successfully using Gem with live camera input on a Mac with OSX 10.5 and can provide information about the exact computer model and the versions of Gem/pd/OSX ? The systems here completly freeze when turning on live input with a DV Camera attached via firewire on a MacBook and a G5 Desktop Computer. Otherwise Gem and pd seem to be running fine on those machines and they didn't freeze with 10.4. In April Chris Clepper posted to this list concerning this issue in response to a question of IOhannes Zmoeling and mentioned it was working on his machine. I tried to contact him directly for information but didn't get a response so far. Any help is appreciated. Thanks, Orm

Recommendations for combining many images (256+)
by B. Bogart 20 Sep '08

20 Sep '08

Hey all, Any recommendations as to the best way to combine many images? What I'm after is a kind of long exposure where each image could be weighted differently in order to give it more emphasis. I did a quick test in Gem layering 100 images on 100 rects on top of one and other with 0.01 opacity. Problem it uses too much CPU (seems to be the GPU lagging). I can render all 100 easily on the same machine if they are not totally overlapping. Would gridflow be able to combine 256 640x480 images? CPU solutions (rather than GPU) are best, as I'm hoping for 640x480 resolution and many more images than will fit in graphics mem. Would something like this work: Every channel of every pixel of every image divided by the number of images (256) multiplied by a weight, where all the results are summed? All the images would be loaded into a pix_buffer. What is the best way to accomplish this? Thanks, .b.

Re: [PD] Newbie-ish Math Question
by Matt Barber 20 Sep '08

20 Sep '08

Hi, To truncate, simply use [int]. To round, add 0.5 to all the values before you truncate. If you need something statistically less biased (the above method of rounding will round everything with a fractional value of exactly 0.5 up to the nearest integer, which could cause some positive drift in certain circumstances) -- you can use [expr rint($f1)], which I think will round fractional values of 0.5 to the nearest even integer (5.5 -> 6; -122.5 -> -122, e.g.).
