Dear list,
is it possible to create a media server with Gem, so I can create on the server a resolution of [dimen 7680x3240(, and through network send to each client one part of the Gem window, so I can have a resolution on a 4x3 matrix video wall with fullHD for each display.
Thanks in advance!

yes it is, BUT the bottleneck will be the -- as often -- the readback. Once you create a 7680x3240px texture you need to read it back from the GPU to the host memory to send it to other. There are several ways to do that and without GPU texture compression I'm pretty sure you can't achieve more than 1 fps at this resolution even with the more expensive graphic card you can use gem with. Concerning hardware texture compression, you may be interested in HAP codec (though I don't know if live encoding is available) and nvenc technology. I think there is an embryonal external for the former but don't know any work in Pd with the latter.
so yes it is possible (like everything) but it's a huge challenge and I'll be happy to read how you achieve it :-)

well, the aim is not to render the image on the server and distribute part on the client, but to distribute the openGL rendering on the many client.
maybe somthing like chromium could help : http://chromium.sourceforge.net/ but i never tried it, I have no idea of how texture sharing, or multi pass rendering can be created with this kind of system.
An other solution is to render exactlly le same pacth on every client. the only diference is a "camera" message to the gemwin.

one other solution which comes to my mind is VirtualGL [1] I use it to display OpenGL content on remote computer. It sounds like what Csaba tries to do, but I don't know it's resolution limitation.

hello,
yes, i think a good GPU can perform better rendering a 7k x 3K pixel image than most laptop rendering a fullHD image.
you don't need 6 dual head2go, 4 triple head 2 go is enough.

I'm not very learned when it comes to apple, so I cannot give an authorative answer your question.
anyhow: the number of cores are probably not very relevant here, as most of the work is done by the GPU. a resolution of 7680x3240 does not seem very high for nowadays standards.
the maximum texture size (which is the relevant spec here) for modern cards should be at least 8192x8192 pixels (e.g. my intel gfx-card on my lenovo x230 supports 8192x8192; my quite old (~10 years) nvidia GeForce 7800GTX would support only 4096x4096; what i here from the new nvidia GTX980 it should have a maximum texture size of 65536x65536 pixels).

Dear list,
just wanted to inform you that I managed to have 2x12 fullHD screens connected and controlled by GEM. With 2 Mac Pro and 6 Datapath x4 4K external graphic cards works smooth. It is not visible from the picture, but these squares are cubes, which revolves when someone gets into interaction with the motion sensors. The result is in the attachment:
[image: Inline image 1]
No upscaling, no additional processor between the computer and the video wall. Just smooth 15840x3240 real time rendered pixels. Thanks for your ideas and help during the process.

I'm not very learned when it comes to apple, so I cannot give an authorative answer your question.
anyhow: the number of cores are probably not very relevant here, as most of the work is done by the GPU. a resolution of 7680x3240 does not seem very high for nowadays standards.
the maximum texture size (which is the relevant spec here) for modern cards should be at least 8192x8192 pixels (e.g. my intel gfx-card on my lenovo x230 supports 8192x8192; my quite old (~10 years) nvidia GeForce 7800GTX would support only 4096x4096; what i here from the new nvidia GTX980 it should have a maximum texture size of 65536x65536 pixels).

Thanks Py.
Now it is 30fps, and works smooth. Wanted to have antialiasing but that was already too much for the processors. Latency, hmm I do not know. Let me know how I could measure it.

hello,
no need for a client/server for this kind of resolutions : the most simple solution is to use 2 or 3 powerfull GPU on a single PC.
1 single hi end GPU is able to control 3 UHD monitor (so about 12K x 3K pixels)

Dear list,
is it possible to create a media server with Gem, so I can create on the server a resolution of [dimen 7680x3240(, and through network send to each client one part of the Gem window, so I can have a resolution on a 4x3 matrix video wall with fullHD for each display.
Thanks in advance!

I'm interested in your project--I hadn't considered Gem to serve out video to each display of a video wall. I have been working on setting up a SAGE cluster (scalable adaptive graphics environment) to setup a video wall.
SAGE provides a VNC client plugin that runs on the head node in the cluster and handles breaking up the displays and sending data over the network. My plan is to have a high-res desktop from a VNC server instance on my laptop displayed on the wall. This approach would let me run any media on the laptop I can, with another process handling the synchronization and network traffic.
Not sure about the VNC plugin yet (haven't gotten to it yet). I hope that I can re-compile with TurboVNC to make good use of compression on such large sizes.
