#
A Brief History of 3D Vision

##
1838: Stereoscopy

- Inventor: Sir Charles Wheatstone
- Technique: Presenting offset images to each eye through a stereoscope, creating depth perception.

##
1853: Anaglyph 3D

- Pioneer: Louis Ducos du Hauron
- Method: Using glasses with colored filters to separate images in complementary colors, creating a depth illusion.

##
1936: Polarized 3D

- Developer: Edwin H. Land
- Approach: Utilizing polarized light technology in 3D movies, with glasses that filter light in specific directions.

##
1960s: Virtual Reality

- Nature: Experimental and not widely accessible.
- Features: Stereoscopic displays, head-tracking technology for immersive environments.

##
1979: Autostereograms (Magic Eye Images)

- Creator: Christopher Tyler
- Concept: 2D patterns that allow viewers to see 3D images without special glasses.

##
1986: IMAX 3D

- Innovation: Incorporating 3D technology in IMAX films using polarized glasses and dual projection systems.

##
2000s: Digital 3D Cinema

- Evolution: Digital projection systems, circular polarization, or active shutter glasses enhancing the 3D film experience.

##
2010s: 3D Television

- Trend: Introduction of 3D TVs with various technologies, like active shutter glasses and glasses-free autostereoscopic displays.
- Decline: Waning popularity due to glasses requirement, limited 3D content, and additional cost.

##
2010s: Virtual Reality Resurgence

- Highlights: Introduction of affordable, high-quality VR headsets like Oculus Rift and HTC Vive.

##
Ongoing Evolution
