Re: [PD] pd/gem as vj mixer at win (Vadim Smahtin)
On OSX and Linux pix_share_write and pix_share_read use shared memory between applications to pass pix_ frames. The setup requires giving the shared memory a numeric id, width, height and bits per pixel of the frame. After this frames written by one pd instance can be read from any other pd. OSX will require changing shm defaults in /etc/rc in order to use HD size textures.

It would be better to only read from the drive once, then decode using the CPU a single time, and to only transfer one copy to the graphics card - so it seems either 2 windows in a single pd or a way to pass references to textures already loaded between 2 different pd's is what I'm looking for, but I'll fall back on one machine per projector if required. simon ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list

maybe using gemviewport from pdmtl: http://www.workinprogress.ca/pd/pdmtl/gemviewport.ogg scenario : dual screen, 1280x1024 and 800x600 for your projection. you make a gemwin 1120 width, offset 960 and put your preview in the window that appear in your screen. never tried it myself since i never did a performance. http://wiki.dataflow.ws/PdMtlAbstractions pat - Original Message - From: "simon wise" <[EMAIL PROTECTED]> To: "Sergi Lario" <[EMAIL PROTECTED]> Cc: "PD list" Sent: Monday, February 18, 2008 9:08 PM Subject: Re: [PD] pd/gem as vj mixer at win (Vadim Smahtin) > > On 19 Feb 2008, at 12:06 AM, tim wrote: > >> Sergi Lario wrote: >>> >>> Hi.

My idea was rather to simply sync the messages so that the same video file is loaded by the two pd's separately. I wasn't using any texturing with this setup though, so I don't know if it would work. > Soon I want to try 2 camera views of the same 3D space, I think that > would be much easier in a single instance of pd with two windows! Load the same 3D space in the two pd's and relate the control data in some way ? Tim ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list

I don't know if it is possible for one pd to use textures or buffers created in the other, that would make the preview idea work well with two pd instances.
