A form, image, style or representation visible in ‘three dimensions’(possessing length, width and height) is known in common vernacular as ‘3D’ or ‘3-D.’
A popular device developed by Charles Wheatstone in 1832 was the stereoscope which provided separate versions of a singular image which were viewed by each eye and adjusted by one’s brain to create the proper image. Polaroid filters were similarly married to this process by scientist Edwin H. Land in 1929.
Now that we’re familiarized with some of its basic principles, we’ll look back at some of the classic films of 3-D’s golden era in next week’s post. Be there (in the dimension of your choice)!
