What is 360 degrees Circular Fisheye lens ?

 A fisheye lens is an ultra wide-angle lens that produces strong visual distortion intended to create a wide panoramic or hemispherical image; Fisheye lenses achieve extremely wide angles of view by forgoing producing images with straight lines of perspective (rectilinear images), opting instead for a special mapping (for example: equisolid angle), which gives images a characteristic convex non-rectilinear appearance.

the  VIVIBright 360 degrees Circular fisheye Fisheye lens Large aperture angles are difficult to design and lead to high prices. Fisheye lenses can have many different mapping functions:

With appropriate software, the curvilinear images produced by a fisheye lens can be remapped to a conventional rectilinear projection. Although this entails some loss of detail at the edges of the frame, the technique can produce an image with a field of view greater than that of a conventional rectilinear lens. This is particularly useful for creating panoramic images.All types of fisheye lens bend straight lines. Aperture angles of 180° or more are possible only with large amounts of barrel distortion.

Other applications:Some planetariums use a form of fisheye lens to project a two-dimensional film image of the night sky onto the interior of a dome. The Navitar HemiStar 6.75 mm Fisheye lens is used for dome projection.

Flight simulators and visual combat simulators use fisheye lenses like the Navitar HemiStar in order to create an immersive environment for pilots, air traffic controllers, or military personnel to train in. Similarly, the IMAX Dome (previously 'OMNIMAX') motion-picture format involves

Scientists and resource managers (e.g., biologists, foresters, and meteorologists) use fisheye lenses for hemispherical photography to calculate plant canopy indices and near-ground solar radiation. Applications include evaluation of forest health, characterization of monarch butterfly winter roosting sites, and management of vineyards.

Photographers and videographers use fisheye lenses so they can get the camera as close as possible for action shots whilst also capturing context, for example in skateboarding to focus on the board and still retain an image of the skater.

The first music video to be shot completely with fisheye lens was for the Beastie Boys song "Shake Your Rump" in 1989. In Computer Graphics, circular fisheye images can be used to create environment map from physical world. One complete 180-degree wide angle fisheye image will fit to half of cubic mapping space if proper algorithm applies on. Environment maps can be used to render 3D object and virtual panoramic scene.
