Hi Iohannes,
I just wanted to ask if according to you this approach is feasible with such a gemwin dimension [dimen 7680x3240(.
And if a Mac Pro could handle it with 4-8 or 12 core processor.

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.
cheers

Gents,
what about a six thunderbolt output mac pro connected with 6 dualhead2go arranged in a 4x3 video matrix? Could it do the performance of 3d computing?
Just an idea.

Gents,
thanks for the ideas. Of course the topic is still opened, I just have to make some researches to find the best solutions.
Any news idea are more than welcome. And of course I will keep everyone updated.
Will be back soon:

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.

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.
cheers
