problem to start gem
by bastien beliah 04 Nov '04

04 Nov '04

Hello I'm a pd user (especially for real-time audio) and I want to turn on to new stuff with video. I've recently downloaded gem 0.90 but I really can't open it!!! Every time that I try to open the GEM_INSTALL command I have an error message: "I belive I'm in the wrong directory I thought that the pd-executable would be C:/programme/pd/bin/pd.exe please edit this file and set the PDPATH-variable appropriatly" I don't know exactly what to do. If someone could help me that would be really nice; thanks ps: I'm on pc (win XP) w/pd 0.37-3

GEM: pix_image reloading image already loaded
by Etienne Desautels 29 Oct '04

29 Oct '04

Hi all, I did for an interactive video installation a pd-GEM patch, a kind of video sequencer. I'm on mac os 10.3.5 with pd 0.37 and GEM 0.90. I use pix_image to load images on a rectangle and I have 2 problems with it. First, pix_image have a system to keep each loaded image in the computer memory for using it later if you reload the _exact_ same image. But if you load a lot, say hundreds, of images, that will use a lot of memory. I'd like to know if there's a way to avoid this, a way to release this memory ? Secondly, I think there's a bug in pix_image (and pix_multiimage also). It's suppose to use the data image in the cache if you reload the _exact_ same image, but it doesn't seem to work. That make my first problem even worst because each time you reload the same image, gem will put it another time in memory, so the memory will grow indefinitely. I did the test with pix_image and pix_multiimage and on 2 different computers (powerbook 667 with an ATI and a dual G4 1GHz with an nVidia). Each time I reload the same image, I can see the memory usage of pd growing. The only way to release the memory is to quit pd. It's not an acceptable solution for me because my installation is running all day long and at some point PD hang because there's no more memory and swap. You could try it by using the help patch of pix_image and keep reloading the same image and watching the memory usage of pd in top. Thank you for your help. Etienne

by Tim Blechmann 28 Oct '04

hi all ... just a short newbie question ... how is the structure of the image data in the pixes? my guess is from the top left to the bottom right ... is this correct? cheers ... tim -- mailto:TimBlechmann@gmx.de ICQ: 96771783 http://www.mokabar.tk After one look at this planet any visitor from outer space would say "I want to see the manager."

quick cvs question
by James Tittle II 21 Oct '04

21 Oct '04

...if I have a cvs checkout that is already using a particular tag, do I have to do anything different when committing a new file to it? in other words, do I have to specify explicitly that I'm committing to the tag? ...in specific, I have a copy of the vertex_array branch, and I want to add somethings to it :-) So, do I just "cvs add" and "cvs commit", or do I have to somehow specify to add/commit to the branch tag? thanx, james

Can't create 1024x1024 gemwin? (OSX)
by B. Bogart 20 Oct '04

20 Oct '04

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hey all, I'm trying to create a 1024x1024 gemwindow and I cannot get it to render! The window gets created but it remains totally white and never renders any objects. When I lower to 1000x1000 it seems to work fine black background with objects rendered. I took a little walk through the code and did not see anything limiting a resolution to 1000x1000... I have no idea what is up. 1001x 1001 also does not work... looks like everything over 1000 is no go.

[GEM] pix_coordinate in OS X
by Mirko Petrovich 20 Oct '04

20 Oct '04

Hi all I noticed [pix_coordinate] behaves different in os x and linux. In patch 02.TexCoord, the texture is repeated in Linux and in osx it looks clipped. I wonder if this object is broken or there is a new syntax for the values ? Saludos Mirko

Compiling Vertex Array stuff under OSX
by B. Bogart 19 Oct '04

19 Oct '04

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hey all, I'm trying to compile the vertex branch on OSX. I've simply added the src/vertex files to the project and compile when without errors. Upon loading Gem I get the following unresolved symbols: __ZN9GemVertex11setModifiedEv __ZN9GemVertexC2Ev __ZN9GemVertexD2Ev _glBindBufferARB _glBufferDataARB _glDeleteBuffersARB _glGenBuffersARB I'm using OSX on 10.3.2 (Because I tried getting Gem to work on a french 1GHz powerbook and I could not get pix_video to work, only sending a green texture. It works fine in other applications though. Also I can't get pix_film to load a animation compressed QT. It just send a green texture. QT opens it fine directly. These last two issues are based on the gem binary on taproot.dyndns.org/~cgc Thanks all Ben -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.2 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://enigmail.mozdev.org iD8DBQFBbrMcjbOsMZSA25cRAjV9AKCg211G8XwEVsrtjwTdD13YA1nZrQCfQlYW qQgaB9gc2olYM8mT//fDPJU= =Bzkh -----END PGP SIGNATURE-----

Image processing

Hi, I was wondering if anyone knew if it was possible to analyze an image in GEM? Something like what color pixels are and at what location? Thanks Jay
