GLASSES ALTERNATIVES

摘要

Anaglyph, active-LCD-shutter, and passive-polarizer 3-D glasses may be the most prevalent options available today, but they're not the only candidates. Keep an eye on Dolby 3-D, which blends the attributes of the anaglyph and passive-polarizer approaches. Like both of these traditional approaches, the Dolby 3-D glasses are relatively lightweight and inexpensive.rnLike anaglyph, Dolby 3-D relies on fine-grained-color-spectrum segmentation to differentiate between right- and left-eye-intended images. Unlike anaglyph and like passive polarization, however, each eye receives a full-spectrum presentation. And unilke passive polarization, a theater retrofit to install an expensive silvered screen is not necessary.
