3-D Definitions before you start

4-D - Length, width, and depth are three dimensions. Time becomes the 4th dimension when a few seconds of animation take place...

Stereoscopic: A method of blending images of two slightly differing perspective points into a single image giving the impression of depth presence. When viewed properly they allow you to see in 3-D. Example: Stereo cards, View-Master reels etc,... For more on stereo pairs, see the Anaglyph link, as well as the stereo pairs link.

Auto-Stereoscopic - Most forms of 3-D, like virtual reality, 3-D movies, Stereo pairs, etc. require some sort of viewing apparatus like goggles, glasses or a viewer. Auto-Stereoscopic is machinery, goggle and glasses free so any passer by with 2 functional eyes can see the 3-D effects.

Lenticulars -There is a layer of lenticles (or lenses) in front of the image. They work as a viewer which self adjusts to whatever distance you are from it. If you are looking at 4-D, not only does it allow you to see the proper stereo views, but also fluid animation, simultaneously... (Thanks to us, and they are available up to 60" x 40")

The 'Muybridge Horse' image, the very first motion picture sequence, was created in 1873 by Edwaerd Muybridge after a barroom bet that a horse lifts all four hooves at once when in motion. This was all the proof that was needed in those days.

Anaglyph- Stereo 3-D you see with red and blue glasses.

Stereo- 2 as in a pair. Stereo pairs are two perspectives of an image that lets you see 3-D with glasses, projection, a viewer, or by means of freeviewing.
