pix_snap example?
by Peter Worth 02 Sep '06

02 Sep '06

hi again. following on from a similar topic i posted yesterday, can anyone give me an example patch with pix_snap in? the help patch for it seems to be not very helpful to beginners.. is the rendering order important when doing this? where can i read more about this type of thing in general? (why wont pix_convolve work on textures is another thing i want to understand) thanks for any info.

gem: storing pix_snap2tex's in a pix_buffer?
by Thoralf Schulze 02 Sep '06

02 Sep '06

hi there, for the purpose of creating visual feedback, i just had a quick shot at storing the result of a pix_snap2tex in a pix_buffer. but somehow these two don't get along very well: i don't get the snapshot into the buffer, while pix_snap2texes help patch ("will take a snapshot of the current render buffer and immediately texture it to any _geometric_ object attached ...") makes me fear that i'm trying to do something impossible here ... tia, thoralf. ___________________________________________________________ Copy addresses and emails from any email account to Yahoo!

Hi List, Is anyone out there using netpd? I am trying to figure out P-ADmin, when I noticed that the load buttons shown on the picture seem to be missing in the patch that I downloaded? Does anyone have a version that works? or know what the problem could be, and how to fix it. http://www.netpd.org/Pad -- B~ www.cypod.co.nr

It's the other way around: ALSA's OSS emulation is a simplified way to access the ALSA devices. To directly access the ALSA devices, the application, Pd, needs to do a bit more configuration, which seems to be broken somewhat in Pd. > while we're at it, another question regarding midi: > you wrote a while ago > (http://lists.puredata.info/pipermail/pd-list/2005-10/031793.html) > that it is possible to get data from an usb midi > controller into pd by using the /dev/midi* files.

I don't remember what distribution you're on, but on Debian based systems you can just add your soundcard modules to /etc/modules. They will get loaded in the order they appear there. So add your normal soundcard module there and then snd-usb-audio at the end there to make the USB midi device show up as the last device. You may also want to load "snd-seq-midi" there, and make sure, "snd-rawmidi" is loaded as well, but I guess, it is already. Regarding the midi devices: If you start Pd with "-mididev 2" it will try to open /dev/midi1, if you start with "-mididev 1,2" it will look for /dev/midi0 and /dev/midi1. It's always the -mididev number minus 1. Another example: -mididev 33 will search /dev/midi32 Do you have more than one USB sound/midi card? Then I could also tell you some more tricks how to configure these to a specific order involving the "pid=" and "vid=" module options for snd-usb-audio. Just make sure you don't load the old OSS modules (add audio usb-midi to /etc/hotplug/blacklist Regarding the midi problem: Here I would say, using -alsamidi should be the preferred way. Pd's alsamidi support is quite good, but it's missing one crucial feature: autoconnect to devices on startup. Hopefully it will get this one fine day, then the hassle with OSS midi will be over.

Soft Rock EP
by Paris Treantafeles 01 Sep '06

01 Sep '06

Hi Claude, I finally have downloaded and watched your Soft Rock EP and wow... great stuff! I may be biased because it's quite similar to some of my own work - even without the GridFlow abstraction that you shared :-) If you don't mind can you tell us how you captured the visuals? They look very good - were you writing to disk (say from Gridflow to Gem?) or sending video out to another machine to capture. Thanks for sharing! p

messing with help-patches
by Roman Haefeli 01 Sep '06

01 Sep '06

hi all bravely i tried to clean the mess i have with all the help-patches lying in different places and came to the conclusion, that there is no obvious way to do it right now. although i use pd for at least two years now, several things are still unclear to me (and maybe to others, too): - what is the 'offical' (non-deprecated) naming-scheme for help-patches: help-<name>.pd, <name>-help.pd or just <name>.pd (the last seems not to work, but i found some helppatches named after this scheme) since pd's own helppatches are named after <name>-help.pd, i assume this the 'official' one. - where are they supposed to be? i found helppatches in the following locations (i didn't place them by myself, they all have been put there by their installers) * pd/extra/ * pd/extra/<lib>/ * pd/doc/5.reference/ * pd/doc/5.reference/<lib>/ * pd/doc/<lib>/ * pd/doc/<lib>/<blablablabl>/<blablabl>/ since the helppatches cannot be reached from the helpbrowser, when they are located in pd/extra, i'd say this is not the way to go. it's handy to have an overview of all objects of a certain lib. also would it be nice to have the helppatches of the libs separated from pd's own helppatches. from the users point of view the following points would make life easy: -all helppatches are named after <name>-help.pd, which makes browsing easier - pd's own helppatches are located in pd/doc/5.reference (as it is now) - helppatches of the libs are located in pd/doc/5.refernece/<lib> the only problem i see here, is that one has to add an extra -helppath for each lib. it would be nice, if that could be avoided by searching pd/doc/5.reference recursively. i didn't find any documentation about this topic and i intentionally did not search the archives, since i'd like to have this discussion come to a final conclusion. the above can be considered just as a starting point. roman ___________________________________________________________ Telefonate ohne weitere Kosten vom PC zum PC: http://messenger.yahoo.de

using pix objects on rendered graphics in gem
by Peter Worth 01 Sep '06

01 Sep '06

hello. i havent used gem much before, sorry for asking this but i cant find any answers in documentation. i've got some geos being rendered to the screen, and i want to apply a convolution to the entire result.. can i use pix_convolve for this in some way, or can it only be used for image files and textures etc? and is there a better or cheaper way to do this than use convolution? i just want to blur everything (a soften effect not a motion blur). thanks. pete.
