Three dimensional (or 3D) refers to objects with dimensions that extend beyond their base. The term is used in a number of ways, including when discussing three-dimensional movies that require special glasses to view.
Although many people believe that the release of Avatar in 2009 ushered in the age of 3D cinema, the first stereoscopic movie came out in 1922. The technology has been in and out of the mainstream ever since, but James Cameron’s film re-energized interest in it. 3D is now available for most new releases in theaters.
The concept behind 3D is based on the way our eyes work. When we see two different images of the same object, our brain combines them to create one picture in three dimensions. The original 3D movies used red and blue lenses to separate the images, but polarized glasses can do the same thing without requiring color-specific glasses.
3D technology also comes in handy for viewing 3D images on a computer or television screen. While it is not as immersive as seeing a movie in 3D, it can still provide an interesting experience. For this reason, many manufacturers offer both 3D monitors and TVs for sale. Some even allow you to watch your favorite movie or play a 3D game on a regular 2D television, without the need for special glasses.
Another application for 3D is in digital art. For example, the artist Yayoi Kusama uses bright colors to create paintings that appear to jump off of the wall. She often creates patterns that are psychedelic in nature, and her works inspire people to be creative. 3D art is also a great way to engage students in online learning. It can help students grasp concepts more quickly and increase their attention levels.
While there are many benefits to using 3D in education, it is important to keep in mind that it can cause some eye discomfort and nausea for some viewers. This can be due to a condition called convergence-close focusing disconnect, which can be treated with glasses, exercise, or rarely, surgery. Some people may also experience headaches or dizziness when viewing 3D images.
For these reasons, it is important to consider the benefits and risks of 3D technology in education before making any major investments. However, there is no doubt that this technology will continue to grow in popularity and find new applications as the industry advances. By continuing to improve the quality of 3D systems, the educational world will be able to offer its students more immersive and exciting learning experiences. For this reason, 3D is likely to become an essential part of the future of higher education.
