Step 4Overview
So basically we will have two photoframes, each one will show the left and right image of a stereo photo, and the half-silvered mirror will combine the two images.
With the polarizing glasses on, we will see a stereo 3D image.
In the picture, the blues rectangles are the screens, and the black line is the hlaf-silvered mirror.
If you have started following me, (and I know that my instructions can be a bit hard to read), you will say that we also need to put a polarizer film over both screens in order to polarize the image coming form them.
Here comes a nice trick: LCD screens ALREADY HAVE a polarizer film over them.
Try to look at your monitor through a piece of polarizing film, and you will notice it immediately!
And the even more funny thing is, that a mirror also inverts polarization.
This means, that really all we need is the two displays, an half silvered mirror, and a pair of glasses with polarizin lenses (later we'll see how to make them) and we have a 3D display.
Cool, isn't it?
