François Quévillon’s Dérive

»This interactive installation invites to explore 3D models of spaces that are transformed according to environmental data collected in real time on the Web. A computer vision interface enables the public to interact with a representation which’s appearance and level of recognition are determined by information on local meteorological and astronomical phenomena. In addition to their visualization, the data transmited by remote environmental sensors are sonified.«


3D Point cloud of Montreal (Quebec, Canada)


SRTM (Shuttle Radar Topography Mission) data of the U.S. Geological Survey converted to a 3D point cloud. Rhône-Alpes region in France

»Dérive was initiated during the Géographies variables residency program in April 2010. Inspired by LiDAR datasets and the growing number of augmented mapping applications, models of distant locations were created by the use of photogrammetry, geomatic data and traditional modeling. These 3D point clouds provide fixed XYZ coordinates that are used in a changing virtual space which ressembles a dynamic particle system. The display and positions of the points and of the wireframe connecting them are determined by the following environmental information as a mean to evoke or simulate them.

Local time : Point size and brightness (relative to sunrise and sunset)
Temperature : Point color
Cloudiness : Point saturation and brightness
Wind : Point displacement reflecting speed and direction
Visibility : Intensity of a depth of field effect and transparency
Humidity : Depth of field focus distance and point sharpness
Precipitation : Random lines drawn from the sky are connected to the ground

The sound synthesis process uses these data and atmospheric pressure to generate an interactive sonic environment.«
