trouble with PiDiP
by stotz 11 Apr '03

11 Apr '03

hi list, yves i tried to install PiDiP v.0.11 on my Debian system with pd 0.36. i succeeded in configuring and compiling without any error messages and i load the library after PDP , as it is stated in the INSTALL file. still, when i run pd, i get the following error messages: /usr/local/pd/externals/pidip.pd_linux: /usr/local/pd/externals/pidip.pd_linux: undefined symbol: ang_d /usr/local/pd/externals/pidip: can't load library any ideas ? oliver ------------------------------------------------- This mail sent through IMP: http://horde.org/imp/

making a transposable triggered sampler
by Mark Khemma 11 Apr '03

11 Apr '03

Hello, I've been trying to create an abstraction where it is simply a sample to be triggered that can be transposed as well. I looked at the help-docs (sampler.transpose) and I'm still clueless on how to create one (i'm still quite confused on how to use tabread4~. The example doesn't exactly fit my needs b/c it simply loops/transposes as oppose to bang/transpose So, I was wondering if anyone out there can send me an .pd file where all it does it allow me to bang the sample and be able to transpose that banged sample whenever I wish. I really appeciate it. or of someone made an external specifically for this situation, even better. send me a link. A 1000 Thanks, Mark .k

Updating help files
by Nick Colvin 11 Apr '03

11 Apr '03

Hi, I'm a newbie. As I pore over the help patches, I frequently come across small typos, inconsistencies, mistakes, etc. I'm not trying to be critical, but my anal retentive ass has this uncontrollable urge to fix them, and in doing so make the journey to Pd land that much easier for future newbs. So my questions are, if and when I edit the help patches, to whom should I send them (I assume Miller, but want to be sure) and would they be welcome? Nicholas.

I've had no problems doing video out using the nv drivers and my geForce2MX under linux... I was just using the suggested twinview settings in the nv documentation, have worked with version 1??? 2??? and 4??? (I can't remember the exact numbers)! "connectedDisplay" does not look like a familiar NV flag...

GEM: how to help myself
by Brad Kligerman 11 Apr '03

11 Apr '03

Hi- I'm trying to figure out how to use the GEM object pix_blur. I don't believe that it is documented. So my question is both specific and general--- 1- What are the right inputs for the pix_blur object? 2- And more importantly, where can I find this information?... ie. by looking in a uncompiled file to figure it all out for myself. Thanks for any help. brad. -- Bradley KLIGERMAN architecture + mÃ©dia Ecole d'architecture de la ville & des territoires Ã Marne-la-VallÃ©e 10-12, avenue Blaise-Pascal 77420 Champs-sur-Marne France

Forgot to say that this is on a PentiumII350, so perhaps thid is one point with regard to the 60msec ASIO latency...but don't know for sure..

I tried to do this but all i gor was an empty image... is it >possible >> to do masking with videos? And videos and images? yes this is possible using alpha channels and pix_composite or you can try pix_chroma_key which doesn't require the setting of an alpha channel (it also works with YUV images). pix_chroma_key takes a message for the "value" of the color to key with and a "range" which is a +/- offset to make keying a bit easier. in the case of the dancer you would make the key value equivalent to white and give a small range to cover any pixel value differences and that should make the other image pop through the white part of the dancer image, with the black part masking out the rest of the image, > And finally, do the two >> sources need to have the same size (like 400x300)? yes. there is no auto-scaling built into any of the objects. the reasoning behind this comes from the idea that GEM gives up a bit of convenience for performance. also that most people would 'tune' their patches to use the same image sizes to avoid the built-in scaling anyway. pix_resize currently resizes an image to the next highest power of two, but could probably be made to work with arbitrary image sizes as well. cgc

Ed, here is the reply again, this time to the correct list. You use the expr object, I am not sure but I think it is included in the main distro, anyway it is a C-like expression evaluation object, if it is not with the main distro you can check it out at http://crca.ucsd.edu/~syadegar/expr.html > > --- Edward George <ed(a)suppose.co.uk> wrote: > Hi > > Max > > > Try... > > > [moses value] eg [moses 10] > > > then right click on it and select help to see > more > > > information. > > > > > > Cheers > > > Ed > > > -----Original Message----- > > > From: pd-list-admin(a)iem.kug.ac.at > > > [mailto:pd-list-admin@iem.kug.ac.at] > > > On Behalf Of max Min > > > Sent: 03 April 2003 11:27 > > > To: pd-list(a)iem.kug.ac.at > > > Subject: [PD] if-function > > > > > > hi list! > > > > > > just beginning, so maybe this is a silly > question: > > > > > > i want to make something like a simple > > > "if"-function. so if a number is > > > bigger than a certain value it should be passed > > on, > > > otherwise a zero > > > should > > > be passed on. > > > anyone know how to do this? > > > > > > thanks for any help. > > > max. > > > > > > > > > > > > ________ > > > max Min | www.maxmin.ws > > > look at www.os3000.org > > > > > > > > > > > > _______________________________________________ > > > PD-list mailing list > > > PD-list(a)iem.kug.ac.at > > > > > > http://iem.kug.ac.at/cgi-bin/mailman/listinfo/pd-list > > > > > > > > > _______________________________________________ > > > PD-list mailing list > > > PD-list(a)iem.kug.ac.at > > > > > > http://iem.kug.ac.at/cgi-bin/mailman/listinfo/pd-list > > > > > > __________________________________________________ > > Yahoo!

Compiling on RH 9
by Timothy Rolls 10 Apr '03

10 Apr '03

Greetings, I have just gone from Red Hat 7.2 to Red Hat 9. When I tried to compile PD 0.36 on 9, it seems to compile fine. but when I run it, the little window that pops up takes up the entire screen. I had no trouble with this on 7.2. Is anyone else using RH9 yet? I'd like to know if I'm the only one with this problem and if anything can be done about it. It happens both on my laptop and my desktop (I had hoped it was an issue with my laptop). Thanks in advance.

Re: [PD] wacom usb tablet as controller ?
by bbogart＠ryerson.ca 10 Apr '03

I think the more generic object makes more sense, the most flexible that works with multiple devices. For the end user experience (wanting each axis come out of a different outlet) Then a a set of abstractions for those devies using the generic object could be made. Still have a "tablet" object, acts just the same way, but can easy be changed (at the patch level) to a mouse object... my 2 cents.
