Thanks for your nick work! How should I specify FOV if my horizontal FOV and vertical FOV are different?

Hi, We convert horizontal FoV to focal length and assume focal length is the same in the vertical and horizontal directions. With this assumption, vertical and horizontal FoVs will be different if the aspect ratio is not 1.
