What is 3D?
3D is an abbreviation for “three-dimensional.” Objects in the real world can be measured in three dimensions; for example, by measuring the length, width, and height of an object. When we look at objects in the real world, we cansee the width and height of an object (the two-dimensional view of the object), but we can also perceive the depth and distance of the object. We see the world with our two eyes. Because each eye is in a slightly different location, each sees a slightly different perspective of whatever we are looking at. We don’t normally think about these two different views, but if you close one eye at a time,you will see the image that each eye sees. Notice how much different nearby objects appear from the view of each eye. Although each eye sees a different image, we don’t perceive two images. In a process called stereopsis, our brain combines the view from each eye into a single picture, and the combined image includes three-dimensional objects and depth perception. The word “stereopsis” is fromthe Greek words stereo, meaning “solid,” and opsis, meaning “sight.” Stereopsis was first described in 1838 by Charles Whetstone, but scientists and artists have been fascinated with three-dimensional perception for many centuries. While most of the population can see 3D, a small percentage of the population (estimates range from 3 to 15%) suffers from some stereoscopic vision impairment....
