1. A system for compositing an augmented reality (AR) scene, the system comprising: (a) an extraction component, operationally connected to a sensing device for capturing a real-world image, configured for: (i) extracting at least one object from said real-world image into a memory of a data-processing machine; (ii) geometrically reconstructing at least one virtual model from said at least one object; and (iii) compositing AR content from said at least one virtual model in order to augment said AR content on said real-world image, thereby creating the AR scene.
