Virtual Reality : The computer-generated simulation of a three-dimensional image or environment that can be interacted with in a seemingly real or physical way by a person using special electronic equipment, such as the Oculus Rift.
Augmented Reality (AR) : Augmented Reality is a technology that superimposes a computer-generated image, video or 3D model on a user’s view of the real world. Augmented Reality employs device cameras or sensors to map and identify the external environment.

Computed tomography : Non-destructive specialized analysis for acquiring information about an object. It is thus possible to define the internal structures of the object, its manufacture process and / or its successive manipulations and which materials have been used.
CAVE : a CAVE (cave automatic virtual environment) is a virtual reality environment made up of between three and six walls that form a room-sized cube. Projectors display a virtual world onto the interior walls of the CAVE and are then controlled by the movement of an experiencer from within the CAVE.
Multimedia projection: Video images projected onto a wall or other media from a computer or a USB flash drive.
Projection Mapping : Projection Mapping uses everyday video projectors, but instead of projecting on a flat screen (e.g. to display a PowerPoint), light is mapped onto any surface, turning common objects of any 3D shape into interactive displays. More formally, projection mapping is “the display of an image on a non-flat or non-white surface”.
It’s a technique for creating animations designed to be projected onto a surface with irregular relief, and generally seeking to cause optical illusions. This multimedia technology allows you to project light or videos on volumes, recreate large images on structures in relief, such as monuments, or recreate 360 ° universes.
3D modeling: Computer graphics technique that aims to create (by specialized software) objects in three dimensions from real objects or not.
3D printing : Creating 3D objects using a 3D printer, a digital file, and some materials (resin, plastic, etc.). This impression can serve as a mold in order to reproduce the object in other materials (tin, aluminum, gold, etc.).
