Hi all, Jean noel montagne from artsensitif, french NGO, submit the idea of pdpedia a while ago which reach the discussion we had during Pd conf about documentation http://pdpedia.dreamhosters.com/index.php?title=Main_Page maybe this can help... on another side, I would like to ask for funds to the french ministry of culture in 2008 to improve in a collaborative way Pd documentation (in french) and high level patches (in Pd), considering the great job that has already been done by Pdmtl team, hans, frank, jérome...and many others, in order to allow as many artists as possible to get into Pd.... not sure at all about the answer + many thanks to Montreal Pd conv team for this great meeting/event Benjamin - labomedia.net Alexandre Quessy a écrit : > Hi Marius, Tom and all ! > > 2007/8/29, marius schebella <marius.schebella(a)gmail.com>: >> thanks, >> atm I don't know how that works. otoh, can we use the index.txt? that >> seems to contain most of the information. >> that's a great library! >> marius. > > In Pd Montreal Abstractions, it is a patch that parses help file > patches (using pd objects and externals) to look for tags (such as > "Author: ") at the beginning of comments. > > :) > > More people are going to contribute to the PdMtl Abstractions in the > next few months.

multiple platform usb video capture cards (again)
by |||__||| 05 Sep '07

05 Sep '07

hi, i'm trying to find a usb capture card to capture analog signal from a IR camera in order to provide a signal for a video tracking patch. the card shoudn't cost more than 300€. i have a intel mac mini for the installation and because pdp more or less requires linux, i'm looking for a usb capture card that supports linux & osx drivers. because of my research untli now i think it's quite unlikely to find somthing like that outside there, so i was hoping - could anybody tell me some of his experience with usb video capture cards for video tracking? - did anyone run the pinacle studio movie box on pd/linux? - does anyone know of a capture card that supports win/linux/osx drivers? i found some threads about capture cards in the archive but none of them had a hardware advice in this price range. thank you for your help in advance, emanuel

hid[io] and CUI
by Echo Ho 05 Sep '07

05 Sep '07

Hi Hans and all, we hookes up a bunch of sensors&switches to a CUI device (http:// www.create.ucsb.edu/~dano/CUI/) and are now trying to get it read by PD. While it basically does work, we are stuck with 2 issues: using the HID Object, it keeps posting messages of this kind: output this: DESKTOP DESKTOP64 83 prev 83 output this: DESKTOP DESKTOP64 88 prev 83 output this: DESKTOP DESKTOP66 235 prev 235 output this: DESKTOP DESKTOP65 5 prev 11 output this: DESKTOP DESKTOP64 90 prev 83 ... which is not more than annoying for the debug process. How is it possible to switch this off? The other issue is how to find the correct names for the different analog inputs. they enumerate as follows in PD/HID: > [hid] opened device 5: Overtone CUI IN v1.0 > [hid] storing absolute axis to poll Miscellaneous Input, X-Axis > (0x0001 0x0030) > logical min 0 max 1023 > [hid] storing absolute axis to poll Miscellaneous Input, Y-Axis > (0x0001 0x0031) > [hid] could not dequeue element > logical min 0 max 1023 > [hid] storing absolute axis to poll Miscellaneous Input, Z-Axis > (0x0001 0x0032) > [hid] could not dequeue element > logical min 0 max 1023 > [hid] storing absolute axis to poll Miscellaneous Input, X-Rotation > (0x0001 0x0033) > [hid] could not dequeue element > logical min 0 max 1023 > [hid] storing absolute axis to poll Miscellaneous Input, Y-Rotation > (0x0001 0x0034) > [hid] could not dequeue element > logical min 0 max 1023 > [hid] storing absolute axis to poll Miscellaneous Input, Z-Rotation > (0x0001 0x0035) > [hid] could not dequeue element > logical min 0 max 1023 > [hid] storing absolute axis to poll Miscellaneous Input, Slider > (0x0001 0x0036) > [hid] could not dequeue element > logical min 0 max 1023 > [hid] storing absolute axis to poll Miscellaneous Input, Dial > (0x0001 0x0037) > [hid] could not dequeue element and like this in SuperCollider/HidDeviceService: > [ Overtone, CUI IN v1.0, 2341, 4761, 1024458752 ] > [ Collection, GamePad, 1, 0, 0 ] > [ Miscellaneous Input, X-Axis, 2, 0, 1023 ] > [ Miscellaneous Input, Y-Axis, 3, 0, 1023 ] > [ Miscellaneous Input, Z-Axis, 4, 0, 1023 ] > [ Miscellaneous Input, X-Rotation, 5, 0, 1023 ] > [ Miscellaneous Input, Y-Rotation, 6, 0, 1023 ] > [ Miscellaneous Input, Z-Rotation, 7, 0, 1023 ] > [ Miscellaneous Input, Slider, 8, 0, 1023 ] > [ Miscellaneous Input, Dial, 9, 0, 1023 ] > [ Miscellaneous Input, X-Velocity, 10, 0, 1023 ] > [ Miscellaneous Input, Y-Velocity, 11, 0, 1023 ] > [ Miscellaneous Input, Z-Velocity, 12, 0, 1023 ] > [ Miscellaneous Input, X-Rotation Velocity, 13, 0, 1023 ] > [ Miscellaneous Input, Y-Rotation Velocity, 14, 0, 1023 ] > [ Miscellaneous Input, Z-Rotation Velocity, 15, 0, 1023 ] > [ Output, Joystick, 16, 0, 255 ] > [ Output, Joystick, 17, 0, 255 ] > [ Output, Joystick, 18, 0, 255 ] > [ Feature, GamePad, 19, 0, 255 ] > [ Feature, GamePad, 20, 0, 255 ] > [ Feature, GamePad, 21, 0, 255 ] things like abs_x abs_y abs_z abs_rx abs_ry abs_rz do work, but for 'Sliders' and 'Dials' I dont know the name used in HID. I wasnt able to find sufficient documentation on the object, so now I need some help from the pros. (\ /) [- . - 猫earweego_sonicvision www.earweego.net

Anyone in the Dallas area using Pd and GEM? There is some paying work that needs to be done on a large installation there. Knowledge of Macs, HD cams, Plasma screens would be helpful. Chris

trouble compiling pd
by eric labelle 05 Sep '07

05 Sep '07

Sorry to bother with this but I'm trying to compile Pd from the CVS and it keeps failing and something that caught my attention at the end of the configure process is this: checking for special C compiler options needed for large files... no checking for _FILE_OFFSET_BITS value needed for large files... no checking for _LARGE_FILES value needed for large files... no configure: creating ./config.status config.status: creating makefile config.status: WARNING: makefile.in seems to ignore the --datarootdir setting Could it be possible that not having support for large files is causing the problem and if so can anyone indicate how to turn it on? (am using gcc under openSUSE) Thanks for your time helping out a Newbie! Cheers Eric

If you have #include "m_pd.h" then m_pd.h has to be in the same directory as the source file. Martin

Do [singleton]s get loadbangs?
by Phil Stone 05 Sep '07

05 Sep '07

Hello all, I'm trying to figure out how to use [singleton] from [sssad] so that I can instantiate some lookup tables once and only once for use in multiple patches. The [singleton] help patch is a bit cryptic, but I've so far guessed that I can wrap the table-creating object like so: [singleton WTAB waveTables] It appears that the tables are correctly allocated by this, but they are not initialized; i.e. the arrays are created, but the code that fills them in is not triggered, even though there is a [loadbang] in [waveTables] that's supposed to trigger it. So my question is first, am I even close to using [singleton] correctly? and secondly, do objects created by [singleton] get a loadbang? Phil Stone http://pkstonemusic.com

documentation material for Pd related grants, funds, and prizes
by marius schebella 05 Sep '07

05 Sep '07

Hi, the "money for Pd" topic was already discussed often; pd licenses for universities, several other ways to support the development of pd like conventions, google summer of code and so on. although it never lead to results... I was thinking of funds or prizes like the ars electronica festival. I am still not sure if Pd will fit in one of the categories, but I know that you have to send a DVD about the project/community. maybe the pdconv would be a good place for some interviews and shoot good footage. one principle question for me with submissions is, if someone should be in charge of the pd community? like an official speaker, or a table of people. honestly I think no, but without that it will be more difficult to access some of the money. (does pd development need money at all???...) the more tanglible question is, if there is someone who wants to help getting this done, filming, interviewing, cutting, writing, research. marius.
