3DTV without glasses?
[QUOTE=Combwork]... "Just suppose a picture tube was made using two b & W images from seperate electron guns firing onto the back of this ribbed screen. Would this give a picture not too unlike what you see out of your window?"
I saw a 3D demo and the NAB convention about 1992 or so that worked exactly this way. A direct view CRT. 3D without wearing polarizing glasses. It was in color too.
It looked OK near the middle of the screen, but not out near the edges. Paralyx problem?
