Immersive 3D Visualization of Astronomical Data

International audienceThe immersive-3D visualization, or Virtual Reality in our study, was previously dedicated to specific uses (research, flight simulators, etc.) The investment in infrastructure and its cost was reserved to large laboratories or companies. Lately we saw the development of immersive-3D masks intended for wide distribution, for example the Oculus Rift and the Sony Morpheus projects. The usual reaction is to say that these tools are primarily intended for games since it is easy to imagine a player in a virtual environment and the added value to conventional 2D screens. Yet it is likely that there are many applications in the professional field if these tools are becoming common. Introducing this technology into existing applications or new developments makes sense only if interest is properly evaluated. The use in Astronomy is clear for education, it is easy to imagine mobile and light planetariums or to reproduce poorly accessible environments (e.g., large instruments). In contrast, in the field of professional astronomy the use is probably less obvious and it requires to conduct studies to determine the most appropriate ones and to assess the contributions compared to the other display modes
