Some pictures, for which the zenith and nadir display is not required (for example, landscapes, city scenes and the other open spaces), can be produced in the form of the cylindrical panoramas. The cylindrical panorama, just as the spherical panorama, has the 360° horizontal angular scale. But its vertical angular scale is smaller, that’s why one can’t view the “overhead and underfoot” spaces, which are called zenith and nadir, in the cylindrical type of panorama. That is the only difference of the cylindrical panorama from spherical. All the other capabilities of the spherical panorama (the virtual tour production, animation and sound addition, etc.) can be applied to cylindrical panoramas also. The cylindrical panorama viewers are the same as for the spherical ones.
The equiangular projection of the cylindrical panorama with 360°х 68° angular scale.
In commercial projects deadlines and costs play an important role, and some customers just prefer to use cylindrical panoramas. The production of them requires less time than the production of spherical panoramas. You can view a virtual tour made from cylindrical panoramas with viewing angle of 360x150 degrees in the example below.
An example of virtual tour based on the cylindrical panoramas:
