A method for producing an interactive virtual movie which simulates the walking of a user within a real site and exploring the same. A scanning apparatus defines minimal conditions for the capturing of a new photograph, including one or more of: (i) displacement of the apparatus by a distance D; (ii) change of the apparatus orientation by an angle Δ°; or (iii) change of the orientation of the camera with respect to the apparatus by an angle of δ°. A photograph is captured each time the apparatus exceeds one of the predefined minimal conditions, wherein the measurements of the variables is reset after each capturing. The method also includes storing the captured photographs and forming open chains of those photographs captured during a common route photographing session, and forming closed chains, of photographs captured during a common junction photographing. For each of those first and last from among the closed chain photographs relating to the junction, a corresponding similar photograph is found meeting one of the criteria of highest correlation or having the closest field of view direction, and connecting between them.
