Dome Camera Attributes
Treat as VRay Dome Camera – Enables the options in the rollout.
Flip X – Flips the view around the X axis.
Flip Y – Flips the view around the Y axis.
FOV – Specifies the field of view for the VRayDomeCamera.
There are three types of FOV (field of view): horizontal, vertical and diagonal. Horizontal FoV depends on the film gate size, focal length, focus distance and zoom factor. In addition to those four parameters, the vertical and diagonal FOV depend on the image aspect ratio.
