Footage from the 1979 film 'Stalker' by Andrei Tarkovsky is analysed for feature detail and parallax movement. Tracking markers near the camera will move more than those further away, allowing the software to deduce a cloud of 3D points in space. The 3D point cloud is joined to form a wireframe 3D mesh. This 3D shape is a simplified but accurate representation of the environment featured in the film clip. This landscape is then recreated in the real world in full scale sections.
