3 1. 3-D film Three-dimensional film / Stereoscopic 3D film : a motion picture that enhances the illusion of depth perception. - motion picture camera system / computer-generated imagery - special projection hardware and/or eyewear Hatsune Miku Concert (2011) The World s First Digital Diva Performing In 3D Avatar (2009) James Cameron 3 / 20

4 1. 3-D film Stereoscope Anaglyph The early type of 3D Display Charles Wheatstone (1838, UK) Only one person, Small Screen Simple principles Inexpensive equipment Difficulties in the color representation 4 / 20

5 1. 3-D film Polarized 3D glasses Shutter glasses This type creates the illusion of threedimensional images by restricting the light that reaches each eye. Less eye fatigue Simple structure, Low cost The display resolution is reduced by half. The left and right eye images are alternately displayed at very high speeds without dividing lines. Clear resolution (Does not degrade) Flickering Battery replacement 5 / 20

19 about CTNet The CTNet at the GSCT of KAIST in Korea is a research group focusing on interactive performance over high-speed networks. Ranging from unidirectional transmission of performing arts to the joint performance in multiple locations, the group's mission is to develop performance technologies and rehearse networked performances on both technical and artistic scales. This group envisages a new future of networked performances that will change the way performance is planed, produced, published, experienced and appreciated, and we are active participants in every facet of this exciting future.
