valid FSAA levels
by Hans-Christoph Steiner 25 Mar '09

25 Mar '09

I am documenting the FSAA message to the [gemwin]. It seems to me that it only takes the values 0,2,4,8. There is a check in the C++ code, but its currently a little bit useless: void gemwin :: fsaaMess(int value) { if (value == 2 || value == 4 || value == 8){ GemMan :: fsaa = value; } else{ GemMan :: fsaa = value; } } It seems to me that it should issue a warning if 'value' is not a useful value. Also, [FSAA 0( would be an intuitive way to turn off FSAA, it seems to work. .hc ---------------------------------------------------------------------------- I have the audacity to believe that peoples everywhere can have three meals a day for their bodies, education and culture for their minds, and dignity, equality and freedom for their spirits. - Martin Luther King, Jr.

help files gemgl*
by Hans-Christoph Steiner 25 Mar '09

25 Mar '09

I am just looking at some of the GEMgl stuff, and noticed there are no helpfiles for any of them. It seems that it would be quite useful to make a help template for these functions, then generate them automatically, since the objects themselves were auto-generated. It would be very nice to have these help patches already generated from the OpenGL reference, and also included a link, perhaps. I just committed GLdefine-help.pd as a start. Any thoughts on that? .hc ---------------------------------------------------------------------------- As we enjoy great advantages from inventions of others, we should be glad of an opportunity to serve others by any invention of ours; and this we should do freely and generously. - Benjamin Franklin

Fwd: Re: msd library crash..
by dmotd 24 Mar '09

24 Mar '09

this seems to be relevant to gem folks too.. ---------- Forwarded Message ---------- Subject: [flext] Re: msd library crash.. Date: Tuesday 24 March 2009 From: dmotd <dmotd(a)gmx.net> To: Thomas Grill <gr(a)grrrr.org> CC: Nicolas Montgermont <nicolas_montgermont(a)yahoo.fr> hi thomas, okay, a little more investigation leads me to believe that this hanging behaviour is a conflict with Gem. i can reproduce this every time by loading Gem at start with a '-lib Gem' and using -path to specify the msd lib location. opening any patch with a msd/msd2D or msd3D object crashes obviously when the lib initializes and then it must be Gem calling the backtrace? also calling -lib msd:msd2D:msd3D before -lib Gem causes Gem startup to hang and pd hard locks.. if however, i run msd without Gem then the objects load fine, except i am not sure if they work as all the examples use Gem.. the one that doesn't (01_msdtest) will react to a force message, but the links themselves don't seem to be active and an error message is reported: 'error: msd - link : Index not found' gem is from svn rev:2708 thanks, dmotd On Tuesday 24 March 2009 07:25:37 Thomas Grill wrote: > Hi, > can you give any instructions for successful reproduction? > gr~~~ > > Am 18.03.2009 um 15:24 schrieb dmotd: > > hi folks, > > > > i have just tried to run the msd series of objects, which hangs pd- > > gui and > > politely dumps a backtrace to stderr.. > > > > i am using: > > pd/0.42 (pd svn build) > > msd (pd-externals svn build) > > flext (grill svn build) > > > > the system is an ubuntu/64bit hardy heron (64studio) > > > > i'm not sure if this is related to the 64bit architecture or > > inconsistencies > > between flext releases.. anyhow the output is attached.. > > > > if you need any extra information please don't hesitate to ask.. > > > > thanks, > > > > dmotd > > > > <msd-backtrace.txt>

gem and init to 0
by Hans-Christoph Steiner 23 Mar '09

23 Mar '09

So it seems that gem objects are initing everything to zero, things like colorRGB and translateXYZ don't work if you specify less than three values. It seems to me that those missing values should be set to zero, since that is how Pd generally works, for example: .hc ---------------------------------------------------------------------------- ¡El pueblo unido jamás será vencido!

pix_buffer "save" changes colourspace of slot?
by B. Bogart 23 Mar '09

23 Mar '09

Hey all, I've switched my pix_buffers to YUV in order to save memory. I would like to save these slots in JPEG files once and a while. I noticed that the memory used by PD increases dramatically if I save the images. If I don't PD uses the same amount of memory. My theory is that the slots are converted from YUV to RGB in order to be saved. Is there no way to save JPEGs in YUV format, so that the memory use stays low? I can fit around 6000 images as YUV, more like 2000 in RGB(A). But I would still like to be able to save the images in the slots without crashing PD. I'm currently using imagemagick, but would happy switch to libtiff/libjpeg considering the libgphoto/imagemagick conflicts. Thanks, .b.

pix_video grabs with wrong resolution (again)
by adrian goya 22 Mar '09

22 Mar '09

Hello. I found this old thread while searching for a solution to my problem. http://lists.puredata.info/pipermail/gem-dev/2008-11/003729.html I have the same behavior> pix_video displays only a portion of the image, like it was zoomed in. The difference from what Max had back then is that I am using a Fire-i camera with IOXperts driver. If I send a dialog message to pix_video I see two different cameras (only one is actually connected though): "Unibrain FIre-i" and "mycamera". They are the same camera, "mycamera" is just the name given when registering the "Unibrain Fire-i" with IOXperts. When the dialog box appears "mycamera" is selected and the preview is only the top left fraction of the image. I then click on "Unibrain Fire-i" and the images gets fixed: the whole frame is displayed. I then choose "mycamera" and is fixed aswell. I can then work normally. I need to setup an installation that needs to automatically turn on everyday and just work, so this manual setting is unacceptable. I suppose that if I send a device message to pix_video to select "Unibrain Fire-i" and then another selecting "mycamera" from within the pd patch, a similar behavior would ensure and the problem would be fixed. how do device messages in osx work? I get this in pd console with pix_video: [pix_videoDarwin]: pix_videoDarwin: SG channnel Device List count 8 index 6 [pix_videoDarwin]: pix_videoDarwin: SG channnel Device List DV Video [pix_videoDarwin]: pix_videoDarwin: SG channnel Device List DVCPRO HD (1080i50) [pix_videoDarwin]: pix_videoDarwin: SG channnel Device List DVCPRO HD (1080i60) [pix_videoDarwin]: pix_videoDarwin: SG channnel Device List DVCPRO HD (720p25/50) [pix_videoDarwin]: pix_videoDarwin: SG channnel Device List DVCPRO HD (720p60) [pix_videoDarwin]: pix_videoDarwin: SG channnel Device List IIDC FireWire Video [pix_videoDarwin]: pix_videoDarwin: SG channnel Device List mycamera [pix_videoDarwin]: pix_videoDarwin: SG channnel Device List USB Video Class Video [pix_videoDarwin]: pix_videoDarwin: SGSetChannelDevice trying DVCPRO HD (720p60) [pix_videoDarwin]: pix_videoDarwin: SGSetChannelDevice returned error 704 [pix_videoDarwin]: pix_videoDarwin : vdigName is r2 I tried using [device 0, input 0, dimen 640 480( as suggested here http://www.mail-archive.com/pd-list@iem.at/msg15811.html using different device numbers but had no success. any help would be appreciated. I do not know what else to do. Thankyou all.
