Method for achieving roaming capabilities and performing interactive CGI implanting, and computer games using same

An article of manufacture including a computer usable medium having computer readable program code embodied therein for realistically implanting a non-floating Computer Graphic Image object into a real camera image sequence filmed scene, and for obtaining roaming capability therein, the computer readable program code in said article of manufacture including:

• (a) first computer readable program code for causing a computer to, in a first frame of a group of frames of the image sequence, use an area that is substantially close to infinity and therewith to model the picture into which the Computer Graphic Image object is to be implanted by creating therefor imaginary borders consisting of perpendicular planes and a floor;
• (b) tied to the first computer readable program codes second computer readable program code for causing the computer to provide a three-dimensional vector representing the movement of the camera between each frame;
• and
• (c) tied to the second computer readable program code, third computer readable program code for causing the computer expand said vector to a plane by calculating the movement of the camera to the left and to the right of the original location while maintaining its original angles;
• and therewith, to respectively use an imaginary camera to render a 3D object on a screen of a computer and to respectively coordinate the filming camera's angle with the imaginary camera for implanting the Computer Graphic Image object in the image sequence filmed scene;
• wherein the method is characterized by implementing angular noise from the filming camera's angle to the object rendered by the imaginary camera.
