Question: How is 3D gaming possible without glasses, but for movies you need glasses?

To make a 3D image, you need to send slightly different images to each eye. We can do this with hand held things like a 3DS and some TV’s but the problem is it only works if you’re sitting in a very specific space in front of the screen. This cant’ work in a cinema though because everyone is sitting in different places. so you need glasses which work from any angle.
