I’m wondering how the Arnold spherical camera renders scenes? Is the the FOV or is the pixel grid that each ray is traced through being wrapped into a sphere somehow? I don’t think it works like real 360 cameras by using multiple cameras aiming in different directions? Can someone shed some light on this? I’d like to build my own version of it using either OSL or with a Arnold custom .dll plugin so I can experiment with it a bit more. Thanks.
