Lighttwist is a volumetric projection system. It is currently used to project on the Cyclorama, a large cylindrical display (click the picture below to get inside it).
It was invented by Université de Montréal professor Sébastien Roy and is being further developed under his direction by Vincent Chapdelaine-Couture and Louis Bouchard. It was presented to some of us two years ago on the fringes of LGM 2007. In 2009, LGM is coming back to Montréal and Lighttwist is back… with more than a twist.
Sébastien and his team joined us for the Google Summer of Code. In a week we’ll know if this summer we’ll see a Lighttwist related project sponsored by Google.
He also responded to the call for presentations to LGM and will likely present the latest development at LGM. The number of projectors have doubled from seven to 14. For the same cylinder. What’s this twist?
Last but not least, we’re working out the details to run a show on Lighttwist at LGM, with a live video performance, a couple of short movies and a slide show of panoramas. If you produce panoramic movies, or if you produce panoramic images (in cylindrical projection, 360°x29.3° – 7200x600px with the horizon at 1/3 from the bottom), contact me to be featured at the show.
With so many projectors, related computers and big screen, Lighttwist may seem intimidating. But it is not. This weekend Vincent published an addendum to the user guide for the minimalist Lighttwist configuration – on a single PC. Add a few video cards and a webcam and you’re all set for a start into volumetric projection. Did I mention that Lighttwist is Open Source?
