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.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.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 ?
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.
