1. Anaglyph. Each lens of the glasses are in one of two colors. Then
all the double images are those same colors as well. Like all right eye
images are blue and all left are red. then the red and blue lenses
block and unblock images. Since it uses color all color televisions can do it.
2. Polarized. All left eye images have one polarized light wave and
all right eye images have a 2nd different one. Then the glasses just
block the images meant for the other eye. Same as above but color is
not used. Plus the movie can be viewed in full color.
3. Field/frame sequential or eclipse method. One lens of glasses will open while the other one closes and they do this back and forth very fast. Then the image for that eye flashes on screen while that lens is open. Looks just like polarized.
In theaters they are only using polarized and field sequential 3d formats. In the US polarized is most common, but there are field sequential ones as well. Formats 2 and 3 are possible on tv but you have to have a tv made to do them.
4. Interference filter technology
Dolby 3D uses specific wavelengths of red, green, and blue for the right
eye, and different wavelengths of red, green, and blue for the left
eye. Eyeglasses which filter out the very specific wavelengths allow the
wearer to see a 3D image. This technology eliminates the expensive
silver screens required for polarized systems such as RealD, which is
the most common 3D display system in theaters. It does, however, require
much more expensive glasses than the polarized systems. It is also
known as spectral comb filtering or wavelength multiplex visualization
Also there is auto stereoscopic 3d televisions that don't require glasses. Half the pixels angle to the left and the other half to the right. Then when you are so far from the tv the pixels angle into the left or right eye.
