Paris Expo Porte de Versailles
"LightAct's features and the level of support you get, make it our preferred solution for advanced lighting installations."
Philippe Mussard
Director, Epic Lighting
Paris Expo, Porte de Versailles is a permanent lighting installation in the center of Paris Expo Porte de Versailles, designed by a Parisian lighting design agency Seulsoleil.
Lighting designers François Gaunand, Benjamin Cardonnel and Mélina Votadoro were looking for a reliable system that would be able to control 60 DMX universes of Traxon’s Media Tubes based on traffic conditions on the main ring road around Paris, Boulevard Périphérique.
LightAct was chosen because it offered 24/7 reliability combined with a wide variety of programming options including a possibility of integrating custom-built computer-vision plug-ins.
One reActor X1 (predecessor to current reActors) was used. It pulls video feeds from 2 IP cameras installed on the Périphérique and, using a custom plugin, extracts velocity and driving lane for each vehicle in camera view. Based on these parameters a custom-built visual effect generates colored blobs (magenta on the north side of the road and orange on the south) which blink according to the traffic density on their respective side of the road.
"Thanks a lot for your very good job!"

Director, Seulsoleil
LightAct outputs a DVI video signal to Video Micro Converters by eCUE, which map the video signal to the media tubes. LightAct Manager software was set-up to automatically start running the project on system boot-up and re-start it in case of a system crash.
