My company is developing an exhibit which uses projection mapping rendered from vvvv. I am trying to determine the best hardware to use as the exhibit machine.
The patch I’m running has to output to three projectors at 1280X720 each stacking vertically for a total coverage of 1280X2160. Give or take a bit for overlap and blending the edges. I also have a flash UI running outside vvvv in a 4th output which sends commands to determine content projected. I have three file streams for content; two video and one audio.
In General: The best option I think from research.
Single GPU capable of required resolution and triple switch: This seems like my best bet since I can treat the three projectors as one device and thus avoid problems like ensuring multiple file streams are in sync when seeking. Also, have experimented with boygrouping, but trying to keep the budget lower than two machines and two vvvv licenses.
However I haven’t worked with triple heads before so I was hopping for some general feedback. Thanks in advance for any experience or advice.
How easy is it to setup edge blending when using a triple head?
Is there any added difficulty when stacking outputs vertically with a triple head as opposed to the more conventional horizontal like the multi-monitor setups these devices are designed for?
Any GPU recommendations from experience would be great as well.
