physical modeling objects for pd
by Cyrille Henry 02 Dec '03

02 Dec '03

hello, I have made a serie of objects for physical modeling with pd. The object send Data but NO AUDIO. the aim is to generate data for the control of an audio synthesis and/or video synthesis... it's just like http://www.sodaplay.com/ for pd. I upload sources + object for windows and linux + exemples here : http://drpichon.free.fr/pure-data/physical-modeling/ you nead all the object for testing the exemples. (I'll make a lib later...) I'll be very happy if someone can compile them on OSX (sould be easy : no dependancy) any question / comment / etc are welcome. cyrille

controlling relays from parport
by derek holzer 02 Dec '03

02 Dec '03

hi all, I am trying to use the parport to drive a set of relays, much like in the famous Linux coffee-maker tutorial [thx 2 Johannes Taelman for pointing this one out!] http://www.tldp.org/HOWTO/Coffee.html I have looked at Norbert Math and Iohannes Zmoelnig's 'lp' object, but I see already that it is for writing characters, not sending simple binary signals. Is there another object which might work, or a way to hack 'lp' to do this? Thanks, D.

proper alpha channels in GEM?
by doktorp 01 Dec '03

01 Dec '03

Hi Ive been casually playing around with GEM and pix_image. I cant seem to get it to display an pix with an alpha channel properly. Is there something special I must do> Ive been making images in photoshop and adding an alpha channel manually, and then exporting them in various formats (all powers of 2). The image usually loads fine, but with no alpha. I am of course enabling alpha blending with the [alpha] object. any hints? thanks! -dok

watersurface
by marius schebella 01 Dec '03

hi boys and girls, letÅ½s say i want to render a watersurface with GEM or pdp (opengl) or gridflow. and use the mouse to click onto it and produce some waves. has someone already produced similar things and can give me some hints? Are there some general algorithms for that, or do I have to calculate lightreflections of tons of small squares and rectangles... marius.

PD + Gentoo
by derek holzer 30 Nov '03

30 Nov '03

So.... my search for a Linux distro that will allow me to use my HDSP with minimal hassles has led me to Gentoo, and a whole new set of problems: i.e. that I don't think they look after their audio ebuilds very well. [Or maybe the excellent service of Planet CCRMA spoiled me!] Anyway, I wanted to ask the list three things about PD + Gentoo: 1) Has anybody actually built Gentoo's PD 0.37 ebuild? Jack breaks the compile of it on my machine, and when Jack support is removed, then it breaks because of gcc 3.3. Both of these are documented bugs. 2) Has anybody else compiled PD manually on Gentoo, only to find that it doesn't start up with ALSA [although it runs with Jack fine?]. With the HDSP, PD will open the GUI, but will not connect to the sound card. Also, no files can be opened or started in this state. Something to do with non-interleaved mode. 3) [As a sidenote:] does anybody else find Gentoo's ALSA packages incomplete? Mine are missing Alsaconf, hdspconf, hdsploader and probably some other odds and ends. grrrrrr........ D.

running PD for video work in panther
by Gon Zifroni 30 Nov '03

30 Nov '03

thx to Yves and Adam for suggestions, I actually have installed the 0.37 from Hans's page (after removing manually the 0.36 with thinker tool -allows to browse invisble files-) I followed the end of the instructions for the osx install of PiDiP for changing the pd.command text.. 4. install the present package in /usr/local/lib/pd/pdp_pidip_osx 5. modify the Pd.command textfile to read like this /usr/local/bin/pd -rt -path /usr/local/lib/pd/extra:/usr/local/lib/pd/pdp_pidip_osx/abstractions -lib /usr/local/lib/pd/pdp_pidip_osx/pdp_pidip I even changed the one contained within the app itself this was according to the INSTALL_NOTES file contained in pdp_pidip_osx.tar (also here: http://ydegoyon.free.fr/pidip-for-osx.txt) result when trying to open an example patch is that it doesn't even recognise basic objects and says: " pdp_glx ... couldn't create pdp_v4l ... couldn't create pdp_agc 0.5 ... couldn't create pdp_contrast 0.5 ... couldn't create pdp_saturation 0.5 ... couldn't create example14.pd 2 0 6 0 (text->text) connection failed example14.pd 3 0 2 0 (metro->text) connection failed example14.pd 4 0 2 0 (message->text) connection failed" etc.... I haven't done this yet : "It also requires the installation of Image Magick, imlib2, and ffmpeg." is it even possible in osx? is this the issue? yves, the samples u put there seem real cool especially the tracking and the live shape recognition..not to mention effecttv (real phat shiit, phat=cool, shiit=stuff) do u think this is set-able on my system? thx allot Gon _________________________________________________________________ Talk with your online friends with MSN Messenger http://messenger.msn.nl/

comport
by justin c. rounds 30 Nov '03

30 Nov '03

has anyone had any experience using the comport object on a win2k machine to send data? i'm actually trying to send commands to a lego mindstorms rcx via the ir tower (in case there are any mindstorm users out there), but any related comport advice/patches would be greatly appreciated. one specific question: how should i send data to the object? i've been using messages with bytes (as decimal and hex) separated by spaces, but so far with minimal results. some info on the protocol can be found at http://graphics.stanford.edu/~kekoa/rcx/protocol.html -- thanks! ___________________________ justin c. rounds {multimedia audiovisualist} __ d..b /[]\ /\ [(o)\][:+:][(o)\] --------------- http://justincrounds.org/ ___________________________
