film Mad Max (1979).

      A LIDAR Scanner generates a point cloud by emitting rapidly pulsing (or continuous) laser beams towards objects. As it is doing this, the scanner also rotates around its vertical axis. Simultaneously, a mirror moves the scanner up and down. By turning on its horizontal axis, the scanner systematically runs a three dimensional sweep of its setting. When the laser beam detects it has hit a surface, energy is bounced back to the scanner and a timer records how long this has taken. From this information, a distance can then be calculated to record the location of a single point.2

      This process is repeated thousands of times; points are recorded and fed back to the scanning technology to generate a cloud of relative positions in space. Each of these points is accompanied by an RGB reading, produced from a series of photographs taken by the device’s inbuilt camera. This technology creates a highly accurate, fast and detailed three dimensional image of the scanner’s visible physical environment. This data and accompanying process of generating digital feedback holds countless possibilities.
