To create the visual effect of objects being sliced by the hyperboloid beam, an original miniature filming technique was employed. Model elements intended to appear illuminated in red were coated with the highly reflective "Scotchlite" material, known for its directional reflection properties. A
half-transparent mirror was set at a 45° angle in front of the
motion picture camera PSK-29, reflecting light from a spotlight fitted with a red filter onto the model. This setup achieved red illumination only on specific parts of the model corresponding to the "beam cut," as other objects did not reflect the spotlight's beam. This method is similar to
front projection but differs in that no actors were present in the filmed space. ==Literature==
