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!
Our Daisies plan a mini sleepover, and we planned to make 3-D glasses, but I can’t find the colored acetate! Michaels doesn’t carry anything like that. Very disappointed; it would have been fun!
Don’t give up! 3D glasses are not necessary to enjoy the event and it can easily be viewed without them. We look forward to having you!
I tried today making glasses with the red and blue cellophane gift bags. Tried it with video online. Not so good.
bummed here, too.
Don’t be bummed. You’ll have a great time! The 3D glasses aren’t necessary to watch the event. Enjoy the show!
We are going to make ours with clear acetate (found at a local craft store) and color with red and blue sharpies! Hope it works! Wish I had a 3D image to practice on!
I couldn’t find the acetate at Michaels either. We actually found it at Tap Plastics. If you have one nearby or something similar, then hopefully you find this helpful.
Thanks for sharing the tip. Enjoy the show!
I bought 3D paper glasses at Oriental Trading Company for $3/12 pairs.
My craft store did not have the acetate but, a acetate alternative clear overlay film made from Grafix Dura-Lar and it is not working either I am so sad. Our sleepover starts in 3 hours.
Don’t despair! The event can still be enjoyed without the 3D glasses and there are lots of fun activities that you can do as you follow along. Enjoy the show!
I bought the clear as well and used Sharpies but, not working well. The girls will have fun decorating there glasses so, I do not care.
I purchased clear DURA-LAR (the acetate alternative) at our local Hobby Lobby store. Since it was clear, I colored it with blue and red permanent Sharpie markers and it works great. My Girl Scouts will have so much fun at our belated Cookie Rally Sleepover!
