LIGHTfaktor's Atolla Chandelier for Top Golf

This decorative chandelier located in the lobby stairwell of Top Golf Flagship in Las Vegas, NV at the MGM Grand, consist of 26 suspended LED Rings (white light LED's) with 17 strands of RGB LED pixel hanging through the LED rings.

The fixture is over 32 feet tall and is meant to provide more than just ambient lighting, as its equipped with 5 motion sensing sonar cameras and a direct audio feed, making it capable of interactive motion and audio effects. The fixture and system was designed by Wes Lane and fabricated by his team at LIGHTfaktor. TouchDesigner programming and sensor integration was handled by team member Daniel Schafer.

The fixture uses 6 universes of DMX and is controlled via Artnet by a remote rack mount server running a combination of TouchDesigner and Madrix. Madrix controls the pixels and the audio animation of the pixels. TouchDesigner interfaces with the sonar sensors, audio, and controls the performance of LED rings as well as the audio and motion response effects of the rings.

Through midi commands, TouchDesigner tells Madrix how to respond to motion data collected from the sonar sensors. The fixture has user selectable modes of operation, accessed via iPad, using the TouchOSC app. Basically we give the user the ability to control both the pixels and the rings by triggering cue list and scenes.

The cuelist are differentiated by the type of cues they contain. There are three basic types:

  • Ambient - ambient color effects (pixels) / static and subtle fades (rings).
  • Sound - audio responsive color and pixel animation effects (pixels) / audio responsive sweeps, pulsing, and fading of the 4 zones of rings.
  • Motion - motion sensing people detection of the 5 sonar cameras allows motion responsive pixel effects (pixels) / motion responsive pulsing, and fading of the 4 zones of rings.
