Light Barrier: A Dizzying Array of Projectors and Mirrors Creates Volumetric Drawings in Midair | Colossal

In this third edition, 8 architectural video projectors are split into 630 sub-projectors using an apparatus of concave mirrors designed by artificial nature. Each mirror and its backing structure are computationally generated to create a group that collaborates to form the single image in the air. By measuring the path of each of the 16,000,000 pixel beams individually, light beams can be calibrated to merge in the haze to draw in the air. 40 channels of audio are then used to build a field of sound which solidifies the projected phenomena in the audience’s senses.
