270 deg field of view for a neuroscience virtual reality system

Camera & Cinematics Camera

So, this is a bit of an odd discussion/question. I’m in a neuroscience research lab, and I’m building a virtual reality system for use with mice (the mammals). The setup projects onto three monitors. One is in front and the other two are at 90 degree angles to that one. The mouse is in the middle and runs on a little treadmill in order to move through the environment. The problem I’m currently struggling with is trying to project a 270 deg field on view onto these three monitors so that the mouse gets realistic visual feedback. I know I need at least two cameras to accomplish this, but I was hoping for some advice on how I should set up the cameras. Should I try to span the three monitors (making it so the three cameras are split on a single display), or should I have each camera project onto a different display? So far I’ve mostly tried to split the cameras onto a single display, but this makes is so that the seams between cameras don’t line up with each other. Has anyone done anything similar and have some advice?

Thanks in advance.

Have you tried using the Multiple display system? Unity - Manual: Multi-display
You can then adjust each camera to match the real world display positions so they line up.

Just use three cameras all in the same position, but rotated at 90 degrees from each other. Unity’s Camera FOV is a vertical FOV, so you’ll need to calculate the appropriate FOV to use to get a ~90 degree horizontal FOV.

Then do the multi-display thing @karl_jones just linked to.
