After reading your post having the need of 14 projectors 1920x1080 panoramic blended I look into WO and they are asking $cad $50,000 ... good for you, I can’t justify this expense at least for now. Tell me more if you can? Did you look into Vioso?
It wasn't that much. And correction, we needed to run 12 not 16 projectors.
We only needed 4 licenses of WO (3 x Display PC running 4 projectors each, and 1 x Production PC). And it was v5 pre-owned dongles for 50% off list. $1500 x 4 = $6000
However I believe you can achieve the same effect with Resolume. You don't need WO.
I am in the midst of trials but the concept is to have a master resolume sender for transmitting NDI signal to 3
resolume display PCs controlling 4 projectors each. At the receiver resolume, you simply manipulate the input slice and output transformation as needed.
The issue will be reliability of network gear (pc-end and network switches), sending 1080p30 signals through NDI eats up 150-200mbps of bandwidth per receiver from my quick trials.
Optimally you would need a dedicated heavy-duty gigabit switch for the NDI path. Better yet a 10gb lan card for the sender with a 10gb switch (4-5 NDI 1080p30 recipients will saturate the sender NIC @ 1gb).
