take a 360deg panorama with a nadir shot
(Bottom shot, this example doesn't have one ,i was on a platform & images taken using a fisheye at the 4 corners of the platform - which is wht the bottom/center is so squished)

rotate 180deg
do a polar-2-rectangular conversion
& squeeze to taste (i left this oval..)

been bugging me for a while & i occurred to me yesterday ...
the originating image is roughly 4x18inches so 1:4 ratio

nadir shot is a image of the base of the panorama
if you don't have one & try to make a qtvr movie you get a hole at the bottom

"The nadir (from Arabic nazir, "opposite") is the astronomical term for the point in the sky directly below the observer, or more precisely, the point in the sky with an inclination of -90°.

Geometrically, it is the point on the celestial sphere intersected by a line drawn from the observer's location on the Earth's surface through the center of the Earth. The point opposite the nadir is the zenith.

By association, nadir is also used to mean the lowest point, or time of greatest adversity. In economics, nadir means a low in the price of products. In medicine, nadir can also be used to refer to the lowest blood count for a given patient in a given period of time (i.e., a patient's nadir ANC or absolute neutrophil count).

Nadir also refers to a downward-facing viewing angle of an orbiting satellite, such as is employed during remote sensing of the atmosphere."
