 MAKE 3D GLASSES....

make 3d glass at home

WHAT YOU NEED :

• 3d glasses template
• printer & printing paper
• Cardstock 
• red & blue cellophane
• scissors
• X-acto knife
• clear tape
• anaglyph images**

WHAT YOU DO :

1. download, print and cut out glasses template.
2. trace the images onto the cardstock and cut it out.
3. Carefully cut the "lens" holes using the X-acto knife.(Get an adult's help.)
4. Cut cellophane squares slightly larger that your lens holes.(Note: You may use a plastic baggie coloured with red  and blue marker instead.)
5. Tape the red square over the left eye hole and the blue over the right.
6. Tape the earpieces onto the eye pieces.
7. Use tour 3D glasses to view special 3d images, called anaglyphs!

How 3d glasses work:

   Humans have binocular vision, meaning we have two eyes. Since our eyes are each positioned differently in our heads, each sees a slightly different perspective. But when used together and aided by our brains, we end up perceiving depth and notice even more details due to something called binocular summation. Using 3D glasses and specially designed images called anaglyphs, we can recreate a similar viewing effect.

      Anaglyphs are picture made by superimposing two images of the same object (taken from slightly different perspectives) in two complementary colors-usually red-blue. When viewed with spectrally opposed glasses, like the Ones you just made, the anaglyph appears tree-dimensional. In this case, the red filter over the left ere opposite, perceiving red as black and cyan as white. Through the 3d glasses, the graduation between red and cyan are viewed as graduations of bright to dark, lending the perception of depth. When viewed together, the brain fuse the images into one, three-dimensional view.
