Re: [PD] Does GEM need X-Server to be running
Does GEM need X-Server to be running or does it connect directly to the graphic card? whether you need an X-server, depends on your platform. on windows, Gem uses platform dependend code to create windows and to establish an openGL context. on X-platforms (linux, bsd, irix,...) it will use X/glx, so you will need an X-server somewhere to display (not necessarily the machine you are running Pd on). on OSX it will use Carbon/AGL. on w32 it will use windows/wgl. i don't know of any program that directly connects to the graphics card and still wants to do more than copying pixels into some legacy buffer. Sorry, I forgot to mention that I'm on Linux (Ubuntu 10.04). I need to display the GEM window with the machine I'm running it on. So that means I basically have to keep the system graphics turned on I guess. Try pdp_xv or if its build pdp_sdl Would this allow me to turn the system graphics off and only display the GEM window?

Re: [PD] Does GEM need X-Server to be running
Hi IOhannes, maybe it would be good to know what you want to achieve (or workaround) in the first place. I only need to keep the resources as low as possible since I'm also running a very heavy audio pd patch in parallel with GEM in a hardware like environement. So I guess turning off all graphic processes using cpu will be the best solution. Since the other (audio) patch is running with the -nosleep flag I suppose the graphics cpu load will go to the other cpu anyway in the first place. While keeping GEM at fullscreen I guess the regular system can't be messed around with because there is no access to the regular desktop. That's completely ok with me. I simply wanted to figure out how to save the maximum amount of resources and if it was possible to eliminate X-Server completely. Thank you for the information!

In french only, sorry ! ++ Jack CENTRE DE RESSOURCES ART SENSITIF À MAINS D'ŒUVRES HTTP://WWW.CRASLAB.ORG JOURNÉE OFF PD Le samedi 15 mai Entrée libre Cet événement ouvert aux publics permet aux participants des cours du soir Pure data (formateurs et stagiaires) de cette année de présenter leurs réalisations, partager leurs savoirs-faire et expériences. *LES PRÉSENTATIONS* à partir de 14 H dans la salle Star Trek (2ème ét.) - Voix, accordéon, Pd, clavier de Pierre Mourles - Pure GPS de Jean-Baptiste Merland - Prime Time, avec Jacques Chevrel et Stéphane Privat - Patatas de goma, de Jérôme Abel - Technique mixte, de Farah Khelil, présenté par Sami Majri - VOST, de Jean-Marie Boyer - Pièce sonore pour montée de sève, du LAAB, présenté par Hugo Roger - Yroyto lost, de Elie Blanchard - Difraact de Grégoire Talon - Schwartzpeter et pure data pour une console lumière, de Joseph Jaouen et Hugo Roger *PDPÉDIA LA DOCUMENTATION FRANCOPHONE DE PD* À partir de 17H dans le restaurant de Mains d'Œuvres (Rez-de-chaussée) Avec Technique mixte, une installation interactive de Farah Khelil. Cet événement public est une discussion ouverte sur pdpédia et la documentation francophone du logiciel Pure Data en général. L'idée de cette discussion est de créer un lien entre les avis des experts et développeurs, et la réalité des jeunes utilisateurs de pd, pour que tous s'approprient la documentation de pure data. Ce logiciel est libre, il appartient à chacun de nous de le faire avancer en fonction de nos besoins. Des développeurs de la communauté francophone sont en discussion sur la mise en place d'outils de documentation de pd depuis longtemps, plusieurs pistes ont été proposées mais aucune décision n'est prise, les avis divergent, le sujet est complexe. Jérôme Abel et Jean-Marie Boyer vous proposent dans un premier temps de vous rapporter plusieurs avis contradictoires sur la question, de vous transmettre un maximum d'informations tirées des listes de discussion dédiées à Pure Data. À l'issue de cette présentation, nous vous proposons d'apporter vos propres avis à travers des petits jeux de prise de parole sur une problématique à la fois, liée à la forme et aux contenus que pourrait appréhender cette documentation. Nous rapporterons cette session de discussion à l'ensemble de la communauté pure data francophone. ___ Pd-announce mailing list pd-annou...@iem.at http://lists.puredata.info/listinfo/pd-announce ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Re: [PD] tabletool
Thanks for looking. The multiple object library vs. single multi-function object question is a good one. Personally, it just seems more tidy to me this way, and I don't believe there's any downside to having all the functions packed into one extern. All the memory is allocated per function, so if you only use the sum function, (I think) it shouldn't be significantly different than a separate extern for summing. There is definitely something more Pd-ish about the multiple objects though. I'm open to changing it... For now I'll start using it and see if I ever have a desire to make it the other way.

I'll update the helpfile for [pix_motion_sector] to include a subpatch that does the same thing with [pix_crop], [pix_movement], and [pix_dump]. I think I might also change the source and try taking the distance between current/previous frames using all RGB info instead of a greyscale approximation.

The classification criteria were : 1. the basic computation should be the combination of one number with another number to give another number. 2. the input should be two grids, the output should be a grid of the same size as the left inlet's grid, and the basic computation will combine together the nth element of the left grid with the nth element of the right grid to produce the nth element of the output grid. (if the right-inlet grid is too small, then we loop through its data as many times as necessary) Any other kind of computation is to be put in a different objectclass. Some of them also have an argument of the same kind as [#], such that you have [#fold +] vs [#fold *] vs [#fold ] and so on, while you also have [#draw_image +], [#draw_polygon +], [#outer +], and nearly all imaginable variations on it : if [# ^] exists and [#draw_polygon] takes any $1 that [#] can take, then [#draw_polygon ^] exists. There is definitely something more Pd-ish about the multiple objects though. It depends. functionality such as sinesum is built into Pd as a method instead of a class. The fact is, a class-centric design is preferred for its ease of use, while a method-centric design is preferred for its ease of use, but it's not the same ease of use.

You can send sinesum write read const resize to a table, so there's already a history of methods there. Just because there is a precedent, doesn't mean that the precedent is good. I don't think that a precedent is automatically a worthwhile justification in designing things. But if you talking about whether there is a precedent in Pd (or whether something is Pd-like), then I can find a precedent like that. Now if you want to know what model I would favour, I tend to prefer having anonymous arrays flying around in messages as if they were lists or floats, and then have many classes rather than many methods, but use methods to configure the objects in order to maximise their flexibility, and remove unnecessary distinctions. _ _ __ ___ _ _ _ ... | Mathieu Bouchard, Montréal, Québec. téléphone: +1.514.383.3801___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

[PD] [PD-announce] High Spheres - Open air multi-channel participative concert @ Re-New Festival, Copenhagen, Denmark
Dear all, On 18th May at 19.30 I'll be performing 'High Spheres' a participative multi-channel concert for found objects and reactive generative music for the opening of Re-New Digital Arts Festival, Huset i Magstræde*, *Copenhagen, Denmark. I actually provide only the software and what the music will be like only depends on the people participating. The action takes place open air. No musical instruments are provided, but stones and leaves. Audience can use 6 microphones/loudspeakers to amplify any kind of sound they wish to produce. The whole sonic matter is managed by a Pd-based software, which interacts with the audience processing in real-time the sounds they produce, analyzing the input signals and generating new sounds out of the collected data. An endless sonic data flow which, once started, will live and grow beyond the time-space of the action. If you're in the city you're very welcome to join our self-organized orchestra... Further info: http://marcodonnarumma.com/works/high-spheres/ the audio excerpt there is quite old and was made in AudioMulch, the Pd patch I developed now sounds much more interesting, hope to record the session and post it here. http://re-new.org/program/ @ Thomas Grrr..

[PD] gameport joystick in pd-extended?
Do you mean, how do I connect an old 15-pin joystick to a new computer without a 15-pin joystick port? Get a USB to 15-pin joystick adapter, $5 and up.

Re: [PD] pix_motion_sector
I've updated the helpfile and source for pix_motion_sector. It now compares pixels using RGB vectors instead of just grayscale. Husk - if you're planning to use it, definitely update to this version: http://williambrent.conflations.com/pages/research.html#pix_motion_sector Hans, would you mind updating the version you're hosting as well?

Please correct me if I'm wrong, Doesn't having these as externals instead of abstractions, make it significantly faster/efficient? particularly if you have many of them? no not necessarily. the overhead for message communication between objects is usually quite small, compared to the pixel operations. you would only need [pix_crop]-[pix_movement] without the [pix_separator] (since the crop will have to allocate a new image anyhow), thus no need for the extra copying of data. the only speedup you could expect from pix_motion_sector (i haven't looked at the code), is that you wouldn't have to copy the data for cropping at all, but only use the pixels in the ROI. as for williams argument, that you need less objects, i would suggest looking into abstractions :-) it's definitely less lines of code (at a minimum 10 lines of Pd code) and still only a single object... mfgasdr IOhannes best, J _ _ __ ___ _ _ _ ... | Mathieu Bouchard, Montréal, Québec. téléphone: +1.514.383.3801 ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.10 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAkvtC0wACgkQkX2Xpv6ydvTVNwCgot+wBAkpacUIHBFR3Fg5OmWV xhAAoITZ7wN077ETVr58rSVE9iunYybB =jYk3 -END PGP SIGNATURE- ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list We have nothing to fear from love and commitment. - New York Senator Diane Savino, trying to convince the NY Senate to pass a gay marriage bill -- William Brent www.williambrent.com “Great minds flock together” Conflations: conversational idiom for the 21st century

Re: [PD] pix_motion_sector
Oops - the .zip with the space shouldn't have been up there - that was an earlier draft from today. Just trash anything you downloaded previously and get the current version via the link if you ever intend to use this. The distance between the two RGB pixels is Euclidean, and there's no weighting. I guess I could set up messages for weight arguments and distance metrics to let people fine tune.
