The Digital Planetarium
نویسنده
چکیده
Planetarium technology is steadily shifting from opto-mechanical based projection to digital projection. This technology shift allows the consolidation of many individual projection sources into a single full-dome video-based display and image generation system. This shift is having a profound effect on planetarium show production, educational tools, theater automation, system maintenance, equipment life cycle, required staff and overall theater economics. The history of digital planetarium systems is reviewed, digital planetarium options are discussed, and the advantages of digital planetaria are weighed against opto-mechanical planetaria for both large public theaters and smaller teaching facilities.

Due to the distortions involved, looking at the master does not give a clear idea of the final result once projected on a planetarium dome. The common solution when creating and composing content is to go throug...
متن کاملUltra-Realistic Sightseeing Images Using Digital Planetarium System
Conventional images of tourist sites are trimmed off the unnecessary scenery from the whole scenery in the fixed viewing angle of the cinematographer’s intention. Therefore, when people visit a tourist destination, they are often disappointed about the gap between video image and actual sight. In order to eliminate this gap, we developed the Digital Dome Theatre System in 2009. It can project u...

Planetarian March 2014 Introduction The planetarium has undergone an evolution in delivery (Yo, Chaplin, & Goldsworth, 2011). No longer do some planetariums use analog projectors to display the stars, but rather use digital projectors to create immersive cosmic environments on a grand scale using a multimedia format of images, video, sound, and narration (Rosenfield et al, 2010). Does this new ...
