Fw: Loop record using arrays?
by Ed Kelly 16 Nov '07

16 Nov '07

My solution was to have more than one buffer (e.g, 2), but if you're doing data storage and analysis this is a real pain, because you have some lists of data (e.g. from bonk|) you may want to access beginning at the end of one and continuing into another. The solution is to have a meta-table, storing the start and end-points of the tables in terms of data elements, and if you start in one and extend into aqnothe then the index is wrapped. E.g.: 254 to 286, table 1 extends to 263. table number is 1, so meta-table entry 1 always reads 263 (last entry of table 1). > output of meta-table for one is stored as right inlet of > object, routing values greater than 263 to table 2, and taking 264 away from the table index. The sequence is read using kalashinkov object, so overlap is not noticeable. With windowed audio, there has to be an unnoticable break between the two tables, but >~ and <~ can be fed to *~ objects (right inlet) to accomplish this. Will try to put a patch together, when my computer gets back here :) Lone Shark "Aviation" out now on http://www.pyramidtransmissions.com http://www.myspace.com/sharktracks ----- Original Message ---- From: Tim Flood <timflood23(a)hotmail.com> To: pd-list(a)iem.at Sent: Thursday, 15 November, 2007 8:36:38 PM Subject: [PD] Loop record using arrays? .hmmessage P { margin:0px;padding:0px;} body.hmmessage { FONT-SIZE:10pt;FONT-FAMILY:Tahoma;} Hello Everyone- I am working on a patch that uses several short sample buffers to record live audio input.

Thus it's just a matter of how we explain things to > ourselves. There is some evidence of time's asymmetry, and hence the "arrow of time" in particle physics. It is known as t non-invariance, and is the process by which a particular meson may be observed to decay into several other particles, but this process may not be reversed as in Feynmann's theory of opposite particles travelling in different directions in time. These processes are distinct to a particular subatomic particle, but nevertheless they indicate that there is some definite direction to time. Whereas most subatomic particles have an opposite number (electrons and positrons, protons and antiprotons) (t-invariance), T non-Invariance has been observed only in the weak decay of neutral kaons. ___________________________________________________________ Yahoo!

thanks both, i started to try changing the 'perspec' values, but with the explanations it makes more sense than doing it by intuition. the gemwin-helpfile i had read only explained five arguments with 'view' message, instead of nine which seems to be a different method. thanks a lot ! ----- Message d'origine ---- De : marius schebella <marius.schebella(a)gmail.com> À : reduzierer(a)yahoo.de Cc : Raphaël ILIAS <raphael.ilias(a)yahoo.fr>; pd-list <pd-list(a)iem.at> Envoyé le : Jeudi, 15 Novembre 2007, 2h25mn 10s Objet : Re: [PD] camera angle thanks, roman, I misunderstood the question and posted an unrelated answer, sorry. m.

Re : pix_video and repeat problem
by Raphaël ILIAS 15 Nov '07

15 Nov '07

hi i worked on linux and then find window$ better for gem (i didn't manage to get the dual screen on linux). but i also get "invalid GL enumerant" message. on my laptop i found that just sending [quality 0, mode 0( to every [pix_texture] object stopped the message. then i can set them back to 1 without having this message at every frame rendered (which is not very convenient for debugging with print !). this is not very interesting on a theoric view, but anyway, it works. my card is something like a "Intel Chipset 855GM". sorry my english is worse than ever tonight raphaël ----- Message d'origine ---- De : altern <altern2(a)gmail.com> À : the PureData - mailinglist <pd-list(a)iem.at> Envoyé le : Mercredi, 14 Novembre 2007, 22h04mn 56s Objet : [PD] pix_video and repeat problem hi I am displaying three times the image from the webcam in a GEM window. For this I am using pix_video then repeat 3 then separator for each of the textures that go into the rectangles. This was working fine in several machines with ATI and matrox cards. However I noticed that in some machines it does not work. I am not sure but it looks like the machines that cause error have integrated graphic cards. The error is just some thing like 'invalid GL enumerant' or similar. I dont have the computer with me now. After the repeat I just get the first webcam image shown, the two others just dont work, I get a white rect. any ideas why this is happening? enrike _______________________________________________ PD-list(a)iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list _____________________________________________________________________________ Ne gardez plus qu'une seule adresse mail !

Way of getting CPU load in PD
by B. Bogart 15 Nov '07

15 Nov '07

Hey all, Anyhow have an abstraction laying around that gives the current CPU load? I'm trying to track down a freeze in my long term installation, and so far I have no indication of why it froze. Perhaps an ever increasing CPU load could give me a suspect... Thanks, B. Bogart

bug fixes for Leopard
by Si Mills 15 Nov '07

15 Nov '07

Hi Thanks folks for the advice re: Pd in rosetta. I have tried it and it seems to work, although Jack no longer functions and a patch repeatedly crashed for some reason (worked fine in tiger PPC). Unfortunately Jack features quite heavily in my work at present. I read that some bugs had been fixed for Leopard (concerning the help menu). Any ideas on the timeframe for those fixes to filter through to the next release, and will it be on 0.39 or the Auto-build versions? many thanks Si

Different Users on the same machine...
by Mike McGonagle 15 Nov '07

15 Nov '07

Hello all, I am not quite certain what is happening, but I installed the latests auto build (1114), and when I start up PD under one user on my machine (that does not have a '.pdrc' file), none of the libraries will load. On another user (that has an EMPTY '.pdrc' file), it seems to boot up fine. I tried creating a blank .pdrc file for the user that didn't have one, but it does seem to change anything. Who, what, where, when, how, and why... What else should I check for on this?

camera angle

hi i'm working on a project with gem and i would really be glad if i knew how to change the "angle" of the viewpoint. i tried with [view a b c d e( msg to to the gemwin or with the [camera] object but got nothing like that. i searched in help-files, examples and the html manual but found nothing about it. In project there is a 3D-model that represents a building. I would like it to be impressive but with every camera position i tried, the building appears ridiculous, like a toy (because of perspective i think), or i go "underground" (i mean under the horizontal [square] that represents the ground), or i get a "fish-eye"-like impression. if i move the camera close to the model, it is cuted and we see the inside of the Geo. has anyone got an idea ? thanks raphaël _____________________________________________________________________________ Ne gardez plus qu'une seule adresse mail !
