National 3-D Day – March 18, 2025

National 3-D Day falls on March 18 this year. It is observed annually on the third day of the third week in March. This year, it takes place on March 18. This holiday is dedicated to 3.D. technology and its various mediums. 3.D. technology has a long and storied history and is becoming increasingly common as time passes. Because we have two eyes that observe the world from somewhat different perspectives, we perceive it in three dimensions. Our brains usually blend these two points of view together and the perception of depth is experienced as a result of the disparities.

History of National 3-D Day

3D Space, a nonprofit dedicated to the preservation of stereoscopic images, founded National 3D Day two years ago, but the history of 3D dates earlier than that. In 1838, Sir Charles Wheatstone produced the first stereo 3.D. drawings. Viewing 3.D. photos became a popular kind of home entertainment in the second half of the nineteenth century.

The invention of 3.D. movies, comic books, holography, and other methods of viewing 3.D. representations of the world occurred during the 20th century. Virtual, augmented, and mixed reality technologies have opened up new ways to create and interact with 3.D. material. Because of the cost and techniques required to produce and broadcast 3.D. pictures, they had been mainly limited to a niche in the motion picture industry since 1915. Nonetheless, 3.D. films were quite popular in American cinema in the 1950s, and they had a worldwide renaissance in the 1980s.

Lenny Lipton, a filmmaker, inventor, novelist, and songwriter, has had a lasting impact on numerous parts of 3.D. He began his career in the early 1980s, when he founded StereoGraphics Corp. CrystalEyes, a stereo visualization system launched by StereoGraphics in 1989, was utilized for medical imaging, aerial mapping, and molecular modeling.
He was also the principal developer of the ZScreen polarization modulator, which allowed a projector to show both the left and right sides of a stereo pair on the same screen. This method, which was first introduced in 1988, was utilized for molecular modeling and aerial mapping visualization.
