SDL for cygwin
by Reini Urban 25 Oct '04

25 Oct '04

I've made a big progress for gem. SDL for cygwin compiles fine now. http://article.gmane.org/gmane.os.cygwin/55876 I just have to fix some minor issues with the DLL building, then I will publish this SDL build and then start building pd with gem on cygwin. (native GUI, no X at first) probably some libtool issues will arive. -- Reini Urban http://xarch.tu-graz.ac.at/home/rurban/

Random method in noise~ question....
by chun lee 25 Oct '04

25 Oct '04

Hi there: Out of curiosity, I thought I will take a look at how [noise~] is implemented. While knowing just enough C to write little externals, I am a bit puzzled at the method in which the random number is obtained in here as I only know of rand() method in ANSI C. I also looked at the code for [random] and they look similar. Homebrew? I wonder if anyone could provide some comments on the code or explain a little so that I can know how it works. static t_int *noise_perform(t_int *w) { t_float *out = (t_float *)(w[1]); int *vp = (int *)(w[2]); int n = (int)(w[3]); int val = *vp; while (n--) { *out++ = ((float)((val & 0x7fffffff) - 0x40000000)) * (float)(1.0 / 0x40000000); val = val * 435898247 + 382842987; } *vp = val; return (w+4); } Many thanks Yours CHUN

Pd's RNG.....
by chun lee 25 Oct '04

25 Oct '04

Hi there: Following my previous post "Random method in noise~ question....", I did a bit of research on simple RNG methods. Just wondering, does the methods used in Pd's [noise~] and [random] the implementation of minimal standard/Lehmer RNG method? Or something similar? Apologies if this is off topic, let me know and I will stop hassling you guys;) Many thanks Yorus chun

FW: help-my_canvas.pd update
by Anton Woldhek 25 Oct '04

25 Oct '04

-----Original Message----- From: Anton Woldhek [mailto:anton@woldhek.nl] Sent: zaterdag 23 oktober 2004 23:15 To: 'pd-dev(a)iem.at' Subject: help-my_canvas.pd update Hello everybody, this is my first post to pd-dev, so sorry if this isnt the right forum for this. Anyways, I thought it might be good if the canvas help file included a tip on how to set the canvas in the background. So that you can for example, put a comment on top of it. (You have to cut and then paste everything besides the canvas). How would i go about this, would i change the original help file by Thomas Musil? Or some other way of going about this? Cheers Anton

Re: [PD-dev] PD.app 38-test 7
by B. Bogart 24 Oct '04

24 Oct '04

Ok, I'll try this thanks for the hint. I don't use pdrc because I use multiple versions of PD and externals i development, different Gem branches etc. One configuration does not do enough for me, I would be happy with support for multiple pdrc files, then I would use it! With your method I'll simply configure it with my most often used external versions etc.. (ie stable-ish) Can I add a -helppath with the PD.app?

an idea for Pd structure
by Hans-Christoph Steiner 24 Oct '04

24 Oct '04

So all of the ideas from the pd~conference are still swirling around my head and slowly distilling out. One idea which I think emerged from the conference about how Pd should ideally be structured: - high level objects for rapid programming and beginners - high level objects would be written in Pd so that the user can easily get inside it - Pd should provide a broad set of the lowest level of operators, whether they be for audio, messages, video, etc. One key thing for this idea to work is that objects written in Pd should behave the same as those written in C, C++, etc. Things are already headed in this direction, with such new features as help patches for abstractions, etc. I think this idea should be broadly applied in Pd and there are already a number of examples of this. A set of toxy widget abstractions would be a great solution for GUI objects, and I think the video/graphics packages already provide low level operations, it would be good to see more high level, reusable abstractions for video/graphics. I am currently in the process of implementing a set of cross-platform objects for general access to Human Interface Devices within Pd and this idea is a central inspiration. I am implementing a HID event object then I am making objects written in Pd for higher level access, like [mouse], [joystick], [tablet], etc. That's my two bits, I'd love to hear what others think. .hc ________________________________________________________________________ ____ "Information wants to be free." -Stewart Brand

PD.app 38-test 7
by B. Bogart 23 Oct '04

23 Oct '04

Hey all, I can't figure out how to get the PD.app to load my externals/libs. I can add the paths easily enough but when I try and put anything into the "startup" setup pd can't find it. I've tried absolute paths, relative paths, paths relative to pd paths... still can't get it to load my stuff. It can't seem to find my abstractions either so I guess -path options are not working either. for example my Gem is installed in: /Users/admin/work/libs/cgc/Gem.pd_darwin And console reports: tried /Users/admin/work/libs/cgc/Gem .pd_darwin and failed tried /Users/admin/work/libs/cgc/Gem //Users/admin/work/libs/cgc/Gem .pd_darwin and failed /Users/admin/work/libs/cgc/Gem : can't load library Where are these options stored? I could try editing the file manually to get things moving (maybe) Any other way to supply PD with commandline args with the pd.app (other than .pdrc)?. I start my old pd-0.37-1 with: ~/work/pd/bin/pd -rt -helppath ~/work/abstractions-tot-help -path ~/work/extra -path ~/work/libs -path ~/work/abstractions-v -path ~/work/abstractions-tot -nosound -lib cgc/Gem:pmpd:OSC:zexy:pool (Oh and in the console I get error: .printout.text: no such object) which is caused by Apple-C to copy the console buffer. Thanks B.

Tracker to Mailing List interface
by guenter geiger 22 Oct '04

22 Oct '04

Hi, I was thinking about sending the tracker information to a mailinglist, so that we all can monitor them, look at the bug reports, etc. etc. IMO there are two options. One is to send all the tracker info to the pd-dev list, the other is to have separate lists like pd-bugs, pd-feature, pd-patches or one pd-tracker .... (well, its three options already). Anyhow, in either case I think it would be best if the lists would be hosted by IEM (speaking set up by Johannes) just like the others. In case of using pd-dev directly, this list would have to be opened to noreply(a)sourceforge.net (thats where the tracker notification will be sent from). Please let me know what you think about it.

Pdplay?
by Nicola Bernardini 21 Oct '04

21 Oct '04

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Dear all, at the SOb project (http://www.soundobject.org) we're writing some really cool physical model objects which we are soon going to package and propose to the pure-data externals repository (they are GNU/GPL). However, we now have a problem that we want to solve soon: we need standalone versions of some demo applications (possibly running griPD etc.) we did. It would be nice to have a sort of MaxPlay type of thing (how about PdPlay?). I have some ideas on how to do it and it could be trivial, and therefore it is very probable that someone has already done it somewhere. If no one has done it, I'll hack up one solution and report back to the list as soon as it is done (it is going to be GNU/GPL anyway :). Thank you in advance for all the help you will want to give. nicb +--------------------------------------------------------------------+ |Nicola Bernardini | |E-mail: nicb(a)centrotemporeale.it | |GPG Fingerprint = 6AE6 AF21 E160 D9B3 396E EBAC 906C CFAE 4D65 D910| |Neither MS-Word nor MS-PowerPoint attachments please: | |http://www.fsf.org/philosophy/no-word-attachments.html | +--------------------------------------------------------------------+ -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.0 (GNU/Linux) Comment: Made with pgp4pine 1.75-6 iD8DBQE9mf2qkGzPrk1l2RARAqi/AJ92NXY9HoDWlMbRcu59RkUQNH8E7gCeLU07 +ocbGJWYRzzrrdQO/cG0BcM= =TT6i -----END PGP SIGNATURE-----
