📖 Cultural Story

Coined in the early 19th century from Greek roots to describe the perception of solidity and depth. It became prominent with the invention of the stereoscope (a device for viewing 3D images) and is now central to modern 3D cinema, virtual reality (VR), and augmented reality (AR) technologies.
