3D – How does it work?
Posted on December 6, 2012 by Little Brownie Bakers
Although 3D glasses aren’t required to see the Sleepover show, they will make it even more fun for the girls.
Important! If you are making your own 3D glasses for the Sleepover show, make sure the red lens is over the LEFT eye and the cyan (bluish) lens is over the RIGHT eye. Reversed lenses or clear 3D glasses will not work.
Would you like to know more about how this 3D technology works?
The type of 3D technology that appears in the Sleepover show on your computer is called anaglyph 3D. To view this type of 3D video, you do not need a special television, computer or projector — just a pair of red-cyan 3D glasses.
Anaglyph 3D is made by placing first a red outline layer on the image and then a cyan (bluish) layer. These layers are not aligned directly over the original image, but placed slightly to the left and right. For this reason, the red lens must be over the left eye and the cyan over the right eye. If they are reversed, the image will not appear in 3D. The clear glasses that come with some 3D TVs also will not work.
Remember, red on the left. Blue on the right. Let the show begin!
