added me as a developer
by Hans-Christoph Steiner 13 Sep '07

13 Sep '07

Hey, I just talked with IOhannes about getting added to the pd-gem sourceforge project as a developer. He told me to post here in the same style as pd-dev. For anyone who might not know me, I've been using Pd since 2000, I was a lurker for a couple years, then 2002 starting posting and working on Pd itself. I am currently the main developer of the Pd- extended package, and am working USB HID and arduino interfaces, as well as the mapping library. I would like to be added as a gem dev so that I can update and maintain the Gem help and example patches. I could also fix very minor bugs, like a couple I recently submitted, but I have no plans to start writing Gem objects or extensions since my OpenGL knowledge is theory only, no practice. So now... it's lazy consensus time! .hc ------------------------------------------------------------------------ ---- Mistrust authority - promote decentralization. - the hacker ethic

texunit and framebuffer
by cyrille henry 09 Sep '07

09 Sep '07

hello Chris, would it be possible to add a texunit message to the frambuffer in order to use them in a multiple texture environement? this would be very usefull in order to compute images bigger than the screen, or to have a generic multi-pass, multi-texture engine. (without using pix_snap2tex) thanks Cyrille

gem : using texture for vertex position
by cyrille henry 09 Sep '07

09 Sep '07

hello, i'm tring to do more physics on the GPU, and i'm facing some problems. simulation results can be compute on texture (just like the wave example i send month ago), so now i'd like to use this texture to move vertex. if i acces to a texture with a vertex shader just like on a fragment shader, then it's very slow. (cpu is at 100%) i found that : "vertex textures must be 32-bit-per-component textures, floating point, and they can't use any filtering mode except nearest filtering." i tryed "quality 0" to pix_texture in order to have the nearest filtering mode, but i'm not sure about the 32 bit per component texture. is it the default on Gem? if no, is it possible to change it? anyone already have an exemple how to use a texture to displace vertex? thanks cyrille

I can test ATI+GNU/Linux bug
by Hans-Christoph Steiner 09 Sep '07

So I have an ATI X1600 machine running Ubuntu Studio until Monday (maybe longer). I'll happily work with someone on the ATI CPU pegging bug sometime, if anyone is available.

pix_video bug
by matteo sisti sette 04 Sep '07

04 Sep '07

Hi, When you send an [open( message to a [pix_video] object, even if the open fails (for example because the device is already open by another pix_video or another application, or even if there is NO device to open at all), it always outputs the message: "opened device <n>" (after outputting the appropriate error messages). It shouldn't say "opened device" unless the device has really been opened succesfully. By the way, is the SourceForge bug tracker for project "GEM: Graphics Environment for Multimedia" the right place where to report bugs? I ask this because there are only 4 bugs in the tracker (and 2 in the GEM category of Pure Data bug tracker) while I don't believe that GEM has only 4 known bugs. Thanks Matteo Sisti Sette
