I am trying to use UE4 to make an interactive projection mapping installation. Projection mapping has been around for a while and software like Resolume, Madmapper, and VPT have made projection mapping very very easy and accessible. However, they are not ideal for creating truly interactive projection mapping experiences. How feasible is it to use Unreal for a large projection mapping project (I will be mapping on to a bridge) and I will require about 4 projectors. My idea is to recreate a 3D replica of the bridge and then import it into Unreal where I can make the magic happen. A few issues I see and some questions I have are:
- How does Unreal deal with multiple outputs (4 projectors) ideally output from these four projectors should be stitched together
- Will I still have to use a projection mapping software like Resolume or can I do the whole thing in Unreal. If I have to use a projection mapping software how can I get real-time output from Unreal into Resolume. I am running Windows but I believe there is an application called Syphon that does this for Mac.
I would really appreciate any feedback, advice, and ideas. I think this is definitely a discussion worth having.
