TightLight is the name of an automatic 3D projection mapping method devised by Grady Sain, who describes the platform as a fast, accurate, cheap and dependable way to projection map any number of objects of any size or shape.
“I developed this technique after many years experience designing and directing projection mapped events and shows, using TouchDesigner 088,” Sain explained. “It interfaces with [Atmel-powered] Arduino hardware and custom-built circuits.”
According to Sain, TightLight has two primary goals.
“The first is to help lower the skill level and time needed to calibrate complex projection mapping setups. The second is to address situations that require fast, accurate, and repeated calibration, such as installations and touring stage shows,” Sain continued.
“As an artist, I want to help projection mapping become ubiquitous, cheap, accurate, fast, and most importantly- accessible to artists of all tech skill levels.”
TightLight, says the artist, is an effort to help de-mystify complex projection mapping, all while helping to kickstart a new phase of growth in this medium. As such, the platform does not require a camera, complex shape matching software, or super smart artists/ calibrators/ operators.
“Anyone can be easily trained to calibrate complex setups. In most setups, TightLight is only slightly more difficult than turning on a light,” Sain added.
