I built a website that you can bring up in multiple browser windows, or on multiple adjacent monitors attached to independent computers. Each browser displays a unique QR code. A user can navigate to a second webpage, activate their camera, and point their camera at the QR codes. Each QR code will switch to a unique AR code, then the user can project a single continuous image across all the monitors. It mostly works but I’m missing some 3d math to make the image line up perfect when the angles are weird.
