A Panorama is any wide-angle view of a physical space or view whether in painting, drawing, photography, film/video, or a three-dimensional model. It is an aspect of illusion, immersed in a winding 360 degree panorama and given the impression of standing in a new environment. Panoramic photography became the most common method for creating wide views in the 19th century. There are several types of panoramic projections used to map the full or partial 3D scene onto a 2 dimensional print or screen. These projections are also divided into two (2) formats: Full Spherical Formats and Partial Formats. Full spherical formats include Equirectangular, Cubic and Stereographic –commonly known as “Little Planets” – projections, while Cylindrical, Arc formed, Rectilinear and Partial Spherical projections make up the Partial Formats .
