Patent ID: 7443402

Claim:
A method for producing an interactive virtual movie, which simulates the walking of a user within a real site and exploring the same, comprising: a. Defining first minimal conditions for the creation of a new node; b. Defining second minimal conditions for linking between nodes; c. Moving a scanning apparatus along routes within the site, measuring the x,y, displacement coordinates, 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 said image data and its orientation with the x,y, location coordinates of the node; e. Finding and registering neighborhood links between pairs of nodes to generally create chains of nodes, each link assignment connecting between any two nodes satisfies at least said second minimal conditions required for linking between nodes, wherein more than one link may be assigned to a node; f. Further associating and registering with each created link an exit angular orientation from a first node in the pair and entry angular orientation to the second node in the pair; wherein one of said first minimal conditions is a maximal predefined displacement D between two nodes sampled by the apparatus.
