Located in Saint-Petersburg, Russia it has the biggest dome projection among planetariums in the world. At the same time, as a non-governmental limited budget initiative, it uses intricate money-saving solutions. Invited as a chief video engineer I was designed and implemented a projection setup together with playback system and media server, that makes use of 39 home projectors, instead of 10 big installation projectors. This amount beats previous record of total projectors blended in VIOSO alignment softwareWhile being tough to setup and align, this solution reduced the projection system cost x20 times, still keeping 200 000 lumens total brightness.
All the 39 projectors together form a 12K*12K resolution seamless screen, 60fps playback and 30fps interactive content.
