3-D (stereoscopic) Viewing Aids
- How do we see stereoscopic images on the internet? Barring
electronic means requiring special equipment, the only options are to present
the images as 1) stereo pairs or 2) anaglyph-coded (red-blue) 3-D images. The
first option requires the viewer to be able to "free view" the pairs;
free-viewing is a skill that takes practice to master - some individuals never
acquire the skill. The second option requires "anaglyph" glasses.
These are glasses that have one red lens and one blue lens. The best of these
are designed to closely match the response of color monitors. Get yours here.
