Cinéma en reliefLe cinéma en relief, cinéma en 3D (trois dimensions), ou cinéma stéréoscopique, permet d'enregistrer la réalité avec ses trois dimensions, qui sont la hauteur, la largeur et la profondeur. Les dispositifs mis en œuvre sont calqués sur le principe de la vision binoculaire naturelle de l'être humain. Dès l'invention de la photographie en 1839, des techniques de prise de vue en relief sont mises au point, et des visionneuses appelées stéréoscopes ont été créées pour les observer.
3D scanning3D scanner is the process of analyzing a real-world object or environment to collect three dimensional data of its shape and possibly its appearance (e.g. color). The collected data can then be used to construct digital 3D models. A 3D scanner can be based on many different technologies, each with its own limitations, advantages and costs. Many limitations in the kind of objects that can be digitised are still present. For example, optical technology may encounter many difficulties with dark, shiny, reflective or transparent objects.
Track and fieldTrack and field is a sport that includes athletic contests based on running, jumping, and throwing skills. The name is derived from where the sport takes place, a running track and a grass field for the throwing and some of the jumping events. Track and field is categorized under the umbrella sport of athletics, which also includes road running, cross country running and racewalking. The foot racing events, which include sprints, middle- and long-distance events, racewalking, and hurdling, are won by the athlete who completes it in the least time.
