When you mention 3-D pictures to people the first thing that comes into people's mind are the neat little gimmick photos that companies will sometimes put out that can look three dimensional if you turn them in one particular way or another. But there is so much more to the idea behind a 3-D picture than just some gimmick you got in a pack of baseball cards that lend the idea of 3-D pictures to possibly saving people's lives or at least offering a view of the surface of a planet that we may want to some day visit.
The best example of practical 3-D pictures comes in the form of creative three-dimensional images used on street corners or even in businesses. The idea behind a 3-D picture is to give the illusion of the picture having depth which is the third dimension missing in a two dimensional image. That depth is what can give the person the false impression that they can reach inside of the picture and pull something out of it. It is not easy to make a 3-D picture but if you search the internet you will find that there are artists all over the world that have developed a talent for creating art on the sidewalks and streets, in many cases simply with chalk, that looks three dimensional. Some of it is so realistic that many people avoid walking on the images because they are so adept at giving the illusion of having three dimensions.
Looking around the Internet you will find photos of people doing 3-D pictures in the streets all over the world. These drawings can range from chalk drawings of holes in the sidewalk that seem to lead to a bottomless pit to creating the illusion that something is rising up out of the sidewalk and trying to reach the surface. The reactions to these types of sidewalk drawings are always reactions of either terror or amazement. There are videos of people walking down the street and then panicking when they step on a drawing because, for a split second, they think they have stepped into a bottomless pit. The effects these drawings create when photographed definitely give the illusion of depth and are interesting works of art.
That leads us to the practical application of 3-D pictures. There is a photo circulating the Internet of a company's cigarette break room that has a 3-D picture painted in the floor and the ceiling. The floor picture is of an open grave and the ceiling picture is the view of the sky, and the mourners looking into the grave, that you would see if you were lying in the casket. The images are powerful but they serve a purpose beyond shock value. Cigarette smoking related disease causes a strain on health insurance costs and if a room like that can get people to quit smoking then the company saves money on health insurance and it also helps to save an employee's life.
The use of 3-D pictures can range from the chalk drawings on the street to 3-D pictures of the terrain of a foreign planet that may help us navigate that planet some day. It is safe to say that the world of 3-D pictures is just starting to evolve and their usefulness is limitless.
