ABSTRACT:
Method for producing an interactive virtual movie, which simulates walking of a user within a real site, comprising: (a) Defining first minimal conditions: (b) Defining second minimal conditions; (c) Moving a scanning apparatus along routes within the site, measuring the x,y, displacement, and angular orientation of the scanning apparatus at any given time, and creating a new node at least whenever such first minimal conditions are met; (d) Obtaining an image data at each node location reflecting a camera unit field of view, and associating the image data and its orientation with the x,y. coordinates of the present node; (e) Finding and registering neighborhood links between pairs of nodes, each link satisfies at least said second minimal conditions; and (f) Further associating with each created link an exit angular orientation and entry angular orientation to nodes of each pair.
