1. A method for generating a depth map used to render objects comprising:
- establishing a virtual camera using camera data of a tracked camera which defines a viewpoint for a synthetic scene;
setting the field of view of the virtual camera to the field of view of the tracked camera;
positioning a synthetic tracked object in the scene according to position information of the tracked object; and
extracting depth information of the positioned synthetic tracked object to generate depth map.

Abstract
A method of extracting a depth map from known camera and tracking data is disclosed. The method includes the steps of positioning a virtual camera at the coordinates of the tracked camera, setting the field of view to that of the tracked camera, positioning and orienting a synthetic tracked object to the coordinates of the tracked object, clearing the depth buffer and rendering the tracked object as a depth map.
