NATIONAL 3-D DAY - 3rd Day of 3rd Week in March

National 3-D Day - 3rd Day of 3rd Week in the 3rd Month


National 3-D Day celebrates the art, science, and history of stereoscopic 3-D imagery. Every year, in March, on the third day of the third week of the third month, we explore the technologies used to create 3-D photographs, movies, and art, and we celebrate the many ways that these images have been viewed and enjoyed.

We experience the world in three dimensions because we have two eyes that see from slightly different perspectives. These two points of view are combined in our brains, and the differences between what our eyes see are perceived as depth. This is called stereoscopic vision.

Sir Charles Wheatstone created the first stereo 3-D drawings in 1838. During the second half of the 19th century, viewing 3-D photographs became a very popular form of home entertainment. The 20th century saw the invention of 3-D movies, comic books, holography, and more ways to view representations of the world in 3-D. Recent developments in virtual, augmented, and mixed reality offer new opportunities to create and interact with 3-D media. Advancements in 3-D technologies bring digital images to three-dimensional life, assisting surgeons, projecting art around the world, and educating students.

What does the future of 3-D hold? New developments in stereoscopic capture and display methods will prove to inspire young scientists and storytellers to create the next generation of immersive stereoscopic content. 3-D technology may change the world.
