Hi. I trying to create 2 channel videomixer in pd/gem. And now have 2 questions- how i can make 2 gemwin's to use 1 as preview and other as output, and second- how i can make file list or grid of images to preview my videofiles and then load it's to pix_film. Big thx.
Hi.
About multiple gemwin at same time: I don't know if it's possible, but it would be very useful.
You can see some interesting objects in
http://hangar.org/wikis/lab/doku.php?id=start:puredata_pdvjtools
This objects are only available for Linux.
cheers,
Sergi.

Hi Sergi,
I've done stuff with two gemwins by running pd 2 times and have the two instances communicate over OSC. It worked quite well.

a while ago there was a multiple-Gemwin version of Gem around - I
tried out the binary that was available and it worked fine (I think
on OSX but possibly Linux?) but I used the 2 pd method instead for my
project.
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. 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!
Is the multiple window patch still working? (preferably on Linux, but
also on OSX?)
Or is there a better way to try this?

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.

a window across two screens works fine for me on OSX, I guess it
would depend on drivers, Xorg setup and graphics card on linux but
should be quite achievable, does a preview ok but still it does not
give me 2 viewpoints/camera angles on 1 3D world!
I'll check the other references as well .... thanks

I woudlnt recommend that (gemwin overlapping two windows) at least on my laptop, Nvidia non-free Linux drivers,as I tried this it slowed everything down: I guess it's because the laptop's flat panel and the VGA output dont have the same refresh rate and the X server messes evrything up
It rocks :-)
I've been using the two PD instances communicating over OSC way since a year now and It's fine. Never tried the mutiple Gemwin Gem lib though.
Bye,

i would recommend to try it out. it is highly hardware dependent whether you will have hardware acceleration on both heads for your gfx-card or not.
to discourage people from using it, is similar to discourage people from using full-duplex audio, just because my crappy soundcard/driver does only provide half-duplex (these days seem to be gone thankfully; but then: i would not recommend to use a microphone, since the one in my laptop sounds terrible :-))

Load the same 3D space in the two pd's and relate the control data in some way ?

without textures and lots of pix work this is fine - but I'm wanting
to use plenty of movies and largish graphics as textures, which would
be present from a different point of view in each of the windows.
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.

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.

that seems just what I need, I'll explore ... thanks
