Re: [PD] [GEM] pix_video error on Athlon64
by Drew Browning 07 Nov '05

Tom, It's encouraging to hear you are using GEM on an Athlon 64. I'm using Pd version 0.39 TEST 4 and GEM: ver: 0.90 - I got them both from IEM. Yes, I can view both the the DV cam and Webcam in other apps. When no cameras are connected I get: error: pix_videoDS: No video capture devices found! error: pix_videoDS: COM has not been initialized. Thanks for taking the time to help.

Re: [PD] Pd tutorials!

I have one thing to add in reference to hiding all the guts. Often, just when I think I'm on the verge of understanding a patch, I click on 2 or 3 objects and discover that there's far more than I thought. The hardest thing is remembering which input or output is sending which piece of data. It's all okay, except when I open a subpatch and find another one inside it, and another inside that, and 2 or 3 different copies of another one. Of course, when building a patch for use, then whatever works, but in tutorials I kind of like to be able to see most of what's going on at once. Maybe, if there are abstractions that are used often, they could be explained first in the line of tutorials, so by the time you get to pretty complex stuff, some of the hidden parts are already familiar. -Chuckk Date: Sun, 6 Nov 2005 14:05:54 -0500 From: Hans-Christoph Steiner <hans(a)eds.org> Subject: Re: [PD] Pd tutorials!

[Gem] smoothing of polygons with ATI cards on OS X
by Max Neupert 07 Nov '05

07 Nov '05

(did not go through the 1st time to the list? because of the images as PNG?? now trying JPG..) Hi list, i just found out how to change the behaviour of the ATI graphic card on OS X. the display looks much better now! this is how it looks normally this is how it looks with the antialiasing on the gfx card. the [polygon_smooth] object does not do anything on my system, so i installed the ati driver https://support.ati.com/ics/support/default.asp? deptID=894&task=knowledge&folderID=299 were you can change the settings on the ati card for each app separately. selecting the pd.app does not do the trick. to enable the setting for gem you need to open the package content, navigate to Contents/Resources/ then open the ati control panel go to the 3d settings (openGL priority) click on the add button, a file chooser window pops up. drag the bin directory of the package content into the file chooser window. the bin directory will show up in the drop down menue. select the pd application in the bin directory. this only works with the pd++ package of tigital, unfortunately not with HCSteiners package. hope it helps somebody. m.

Yeah sorry about [pddp_print], I am probably going to remove that object. These are currently just sketches. Before gathering them all into a proper tutorial, standard GUI elements will need to be defined, including standard ways of displaying results. I am not a big fan of [print] because it means that you have to go back and forth between windows. And since its possible to have everything on one patch, I think that is the preferred way. It really demonstrates the always-running, patch-is-the-program idea. .hc On Nov 4, 2005, at 11:13 AM, Samuel Burt wrote: > Hans, > > I think its a great idea to expand the basic tutorials to include some > of the most basic concepts that Pd users need.

Re: [PD] [GEM] pix_video error on Athlon64
by Thomas Ouellet Fredericks 06 Nov '05

Weird. I have an Athlon 64 and windows MCE and never had any problems with Gem. Maybe it has to do with a firewall issue(doubt it). Did you try the latest version of PD? Where did you get your copy of Gem? Can you view the DV and webcam input in other programs? When no camera is connected, do you get the following "proper" error messages: error: pix_videoDS: No video capture devices found! error: pix_videoDS: Could not open device: 0 opened device 0 Tom On 11/5/05, Drew Browning <drew(a)uic.edu> wrote: > No. Installed version is 6.5.1. > > At 06:11 PM 11/5/2005, you wrote: > >Di you install a new version of quicktime? > > > >On 11/5/05, Drew Browning <drew(a)uic.edu> wrote: > > > Hi, > > > > > > I've just installed PD/GEM on an AMD Athlon 64 machine (WinXP) and I'm > > > getting the following error when trying to use pix_video: > > > error: pix_video: could not initialise COM. > > > I'm using > > > Pd version 0.39 TEST 4 > > > GEM: ver: 0.90 > > > The error occurs with earlier versions of PD and GEM too.

Re: [PD] Building a counter problem
by Chuckk Hubbard 06 Nov '05

06 Nov '05

Hi, Brad. The problem is depth-first message passing. And, in PD, if one outlet connects to two things, the messages are sent in the order the connections were made... which you can't tell by looking. If you insert a [print] object after your [+ 1] object, you will see that it always outputs 0 before outputting another number. This is because it first sends its output to the [route], which follows its chain of messages through all the way to the [-1( message, BEFORE sending the same output to the [float] object. So after 4, it outputs 0 and 5, then 0 and 6, etc. It sends its result twice, and the second one replaces the -1 message to the float. Solving it would be as simple as deleting the connection to the [route] object and reconnecting it, so that that message is sent last. Also, I don't know if it matters, but the loadbang means that a 0 is sent on opening. You could just make the float object -1 instead of 0, and delete the loadbang, unless you want an initial 0 output on opening. -Chuckk Date: Sat, 5 Nov 2005 20:36:20 +0100 > From: Brad Kligerman <bkligerman(a)gmail.com> > Subject: [PD] Building a counter problem > To: pd-list(a)iem.at > Message-ID: > <9afc437d0511051136x2bdf06bi50fe74584f14651d(a)mail.gmail.com> > Content-Type: text/plain; charset="iso-8859-1" > > Skipped content of type multipart/alternative-------------- next part > -------------- > A non-text attachment was scrubbed... > Name: counter-1.pd > Type: application/octet-stream > Size: 1186 bytes > Desc: not available > Url : > http://lists.puredata.info/pipermail/pd-list/attachments/20051105/adc49dff/… > >

pd eating memory
by Enrique Erne 06 Nov '05

06 Nov '05

now something I'm little bit more concerned: I've seen (activity monitor) that pd needs more and more memory. it starts about 2.7 MB and without doing anything it just increases about 20kb/second . after two hours it took about 150 MB memory and was still increasing. this happens on osx 10.3.9 using miller's pd without any patches or libs is this a bug ? do you have the same behavior ? thanks Enrique

[GEM] pix_video error on Athlon64
by Drew Browning 05 Nov '05

05 Nov '05

Hi, I've just installed PD/GEM on an AMD Athlon 64 machine (WinXP) and I'm getting the following error when trying to use pix_video: error: pix_video: could not initialise COM. I'm using Pd version 0.39 TEST 4 GEM: ver: 0.90 The error occurs with earlier versions of PD and GEM too. I've tried both USB web cam and DV cam but both give the same error. It works fine on a Pentium 4. Is this an AMD problem? Drew
