Edgeblend with 4 screens

November 14, 2010 | 7:46 am

Hi all.
I work on an installation which need 4 projector.
I would like to know if some of you have experimented such a thing with jitter…
Does matrox could do this job ?
Do you think the edgeblend should be done with a hardware, or jitter could do it correctly (without lag).

have a look at Zachary Seldess quadFlyingSim patch here

its for 4 projector in a 360 room

hope it helps

You can do it with Jitter as long as you have a powerful enough machine. The matrox dual and triplehead2go devices can give you multiple display outputs but they won’t process edge blending onto the data.

how jitter can use TripleHead2Go ?
I mean, is it the TripleHead2Go driver that "emulates" 3 cards mappable to jitter?

any infos would be VERY appreciated :)

TripleHead2Go enables you to set up an extended desktop which the hardware can split in 3. For example, I have set up an extended desktop of 2400×600 and I put my jitter window onto it which the hardware splits into three. Therefore, splitting your image and doing edge blending and geometry correction need to be done in the jitter window.

ok I got it.
in my case, I need to use it for a big system with 3 big screens.
so, if I need to display 3 differents video, I have to use, for instance, 3 jit.pwindow in presentation mode with the correct offset.

thanks a lot for your information!

or better have one jit.window in fulllscreen with the TH2G

then use 3 and a

check the Jitter movie playback optimizations from vade

thanks a lot.
the optimization part is very important, even at the beginning of the architecture making of!
