文档介绍：How 3-D PC Glasses Work
by Shane Speck
Only a few years ago, seeing in 3-D meant peering through a
pair of red-and-blue glasses, or trying not to go cross-eyed in
front of a page of fuzzy dots. It was great at the time, but 3-D
technology has moved on. Scientists know more about how our
vision works than ever before, and puters are more
powerful than ever before -- most of us have sophisticated Photo courtesy
components in puter that are dedicated to producing E-Dimensional Wireless E-D
realistic graphics. Put those two things together, and you'll see Glasses
how 3-D graphics have really begun to take off. eDimensional, E-D and the eDimensional

eDimensional, Inc. in the . and other
puter users are familiar with 3-D games. Back in the countries.
'90s, computer enthusiasts were stunned by the game Castle Wolfenstein 3D, which took place in
a maze-like castle. It may have been constructed from blocky tiles, but the castle existed in three
dimensions -- you could move forward and backward, or hold down the appropriate key and see
your viewpoint spin through 360 degrees. Back then, it was revolutionary and quite amazing.
Nowadays, gamers enjoy ever plicated graphics -- smooth, three-dimensional
plete with realistic lighting plex simulations of real-life physics grace
our screens. But that's the problem
