3D Display

It’s been around for awhile…. (1840)

anaglyphs (red-cyan glasses)stereoscopy (one small image for each eye)diversely polarized images for each eye (won't work on a monitor or on paper)temporal multiplexing (guaranteed headache),lenticular screens (like gifts in cereal packs, quality can be OK if distances are optimized)holography (very difficult, no color, expensive)stereogram dots (“magic” pictures)

Diversely Polarized (allows full color)

3D

Modern technology combines two digital projectors fitted with polarizing filters with the use of polarized glasses and silver screens. A single projector can also be used in conjunction with a simple adapter in the front (a single-cell LCD screen that acts as a quarter-wave retarder, also known as a zscreen) that rotates the polarity of projector's light output several times per second to alternate quickly the left-and-right-eye views. Another system from Dolby Laboratories called Dolby 3D makes use of a special color filter and glasses and has the advantage that doesn't require a silver screen. Also, some theaters use a system that requires no modification on the screen or the projector but uses active liquid crystal shutter glasses that quickly block the views of each eye alternatively.

Problem: Even cool people look dumb with the glasses

Rapid PrototypingAdditive manufacturing technology for rapid prototyping takes virtual designs from computer aided design (CAD) or animation modeling software, transforms them into thin, virtual, horizontal cross-sections and then creates successive layers until the model is complete. It is a WYSIWYG process where the virtual model and the physical model are almost identical.

In 2006, John Balistreri and others at Bowling Green State University began research into 3D Rapid Prototyping machines, creating printed ceramic art objects. This research has led to the invention of ceramic powders and binder systems that enable clay material to be printed from a computer model and kiln fired for the first time.
