How to made 3D goggle ( red /cyan ) to watch 3D movies

Tutorial on Making your own 3D Glasses or Goggles..

                                                                                                         

MATERIALS :Oaktag (sturdy poster board)
Scissors
Clear tape
Basic pattern for glasses
Sheets of red and blue acetate (available at art supply stores)

STEPS : 

1. Cut out the sample pattern (including eyeholes) for your 3D glasses and tape the sides to the center section. You now have your stencil for the actual glasses.
2. Trace the stencil on the oaktag or sturdy poster board. Cut the glasses out making sure to also cut out the eyeholes.
3. Tape the red (left) and blue (right) acetate pieces to cover the eyeholes. Make sure to cut the acetate pieces a little larger than the opening for the eyes. DO NOT get tape on parts of the acetate visible through the eyehole.

HINTS

• You can decorate the glasses using any materials on hand. Encourage students to be as creative as possible!
• The pattern provided is just one possible style. Vary the outer shape of the glasses to make them unique.
• Take a picture of the whole class wearing their glasses. Or, even better, Use the class wearing their glasses as the subject of your 3D photo!

Tutorial on Making your own 3D photo..




3D photo or movie is nothing but combination of two photos. It has two different photo for each of your eyes,which is the main difference with 2D.


Making Anaglyph Images in Adobe Photoshop 7.0

In order to make an anaglyph you need two slightly off-set images.
These can be produced using 3D software applications (Bryce, 3D Studio Max) or they can be captured from a camera(by changin pos as the gap b/w eyes) or pair of cameras .
If you are capturing images from cameras, it is absolutely critical that you keep track of which image is for the left eye and which is for the right eye.
If you are working with a large number of images, I recommend a naming system that goes something like this: 01l, 01r, 02l,02r... and so on.
*For this demo, I'll be using version photoshop 7.0.
The first thing you need to do is open both the left and right images.

In the first image go to Select - All (Control-A), then Edit - Copy (Control-C).

Now go to File - New (Control-N).
The new file matches to the correct dimensions, so hit enter, and finally go to Edit - Paste (Control-V).
Your image will be pasted as a new layer.

You have to label that layer left or right, so rename it depending on which layer it is.

Repeat these steps for the second image.

You should now have a 3-layer image, with layers left, right and background.
Now you need to align the layers properly.

To do this, go to the top layer and select the Opacity drop-down menu.
Slide the bar until it reads around 50%.
You should now be able to see both images at the same time, as the top image is slightly transparent.
Now pick a prominent place on the image which will be your focus.
This should be somewhere near the center of the picture and where you think the eye will be drawn to first.
Use your drag tool:to move the top image so that the focus of the two images are roughly aligned.
The next step is to return the top layer to 100% Opacity.
Notice the white boarder on the sides. 
Now go to Edit - Crop.
This will resize your image so that both eyes take up the entire field.
Now we have to add the color effect.
*Make sure that you had RGB color scheme.
Now, Make sure the right eye image is selected and go to Image - Adjustments - Levels... (Control-L)
Drop down the top menu and select the Red channel (Control-1).
Now, at the bottom where it says Output Levels change the 255 to 0 and click OK.
This should change your layer to a green-blue color (cyan).
Now select the left layer. and open the Level... dialog box again(Control-L).
Select the Blue Layer (Control-3) and change the Output Level to 0 .
Click OK.
This should turn the top layer to bright red.
The final step is to select the top layer (left or right) and in the box where it currently says Normal change it to Screen.
Go to Save Image As (Control-Shift-S) and save it as a jpeg (or tiff or whatever kind of file you need).




3D Stereoscopic glasses are nothing new. In fact you had them when you were a kid and probably didn't even know it. Remember the ViewMaster™ that showed all the cool Disney characters in full 3d? The ViewMaster™ allowed you to look at two pictures of the same thing taken from a slightly different view point and tricked your brain into seeing one 3d image.

In order to see things in 3D each eye must see a slightly different picture. This is done in the real world by your eyes being spaced apart so each eye has its own slightly different view. The brain then puts the two pictures together to form one 3D image that has depth to it.

Still want to know how do 3D glasses work? Keep reading!

Anaglyphic [ana·glyph·ic /"a-n&-'gli-fik/] adjective -- A stereoscopic motion or still picture in which the right component of a composite image usually red in color is superposed on the left component in a contrasting color to produce a three-dimensional effect when viewed through correspondingly colored filters in the form of spectacles.

The mode of 3D presentation you are most familiar with are the paper glasses with red and blue lenses. The technology behind 3D, or stereoscopic, movies is actually pretty simple. They simply recreate the way humans see normally.

Since your eyes are about two inches apart, they see the same picture from slightly different angles. Your brain then correlates these two images in order to gauge distance. This is called binocular vision - ViewMasters™ and binoculars mimic this process by presenting each eye with a slightly different image. Now you're learning! Need to know more about how do 3D glasses work? Read on. The binocular vision system relies on the fact that our two eyes are spaced about 2 inches (5 centimeters) apart. Therefore, each eye sees the world from a slightly different perspective, and the binocular vision system in your brain uses the difference to calculate distance. Your brain has the ability to correlate the images it sees in its two eyes even though they are slightly different.

If you've ever used a ViewMaster™ or a stereoscopic viewer, you have seen your binocular vision system in action. In a View-Master, each eye is presented with an image. Two cameras photograph the same image from slightly different positions to create these images. Your eyes can correlate these images automatically because each eye sees only one of the images.

A 3D film viewed without glasses is a very strange sight and may appear to be out of focus, fuzzy or out of register. The same scene is projected simultaneously from two different angles in two different colors, red and cyan (or blue or green). Here's where those cool glasses come in -- the colored filters separate the two different images so each image only enters one eye. Your brain puts the two pictures back together and now you're dodging a flying meteor!
