The use of the pejorative "silly" when referring to 3D viewing glasses shows an ignorance of the basics of vision and imaging. The use of the viewing glasses permits high quality realistic viewing from every position in the audience, at a relatively low cost. Attempts to get a realistic appearance by just increasing resolution, fail miserably. Real life images extend from a few inches to infinity. No matter how high the resolution, flat systems do not eliminate the serious distortion that is effected when you compress a three dimensional scene all the way down to a flat plane. Squashed pictures are hardly realistic. Autostereoscopic systems are expensive, and not necessary, when you can get better results at lower cost with glasses-based systems. Do you consider sunglasses to be silly, or cool? 3D viewing glasses are very similar in style to sunglasses. And, they do a very good job of eliminating the flatty distortion.
