They've already done it, by locking the cabin door. The cheapest and most effective fix to the problem possible.

At my home city airport, we still have the normal meta detectors and non-mandatory pat-downs. Why? Couldn't a terrorist just drive to my city and fly from there? This whole premise makes the entire current system worthless.

I write post-production software used to do this (and it runs on Linux!). The best results I've seen involve manually breaking each shot into dozens of layers, using rotoscoping. Each set of layers is exported as masks and imported into a compositing application where the images for the layers are projected onto the masks in 3D space. In some cases they build rough 3D models and project the layers onto the respective models. Now they can add a virtual camera and render the scene from both views. Then they bring the footage into a paint system and manually paint in the "missing" parts that now show up because of the change in camera angle. This has to be done for both the left and the right eye.

They have a room of 300 guys in India doing this for Titanic. But the results are INCREDIBLE.

Some automatic techniques involve rotoscoping a depth map by hand (or with a combination of some automated depth map generation, but this almost always has to be tweaked for good results), then using that to synthesize two new views from the 2D footage. Then to fill in the gaps they can use either an automated warping (which looks almost, but not quite, entirely not all right) or hand-painting again.

The upshot is it is a very very manual, labor-intensive process, with somewhat specialized tools. But when done well it looks amazing.

Then don't buy one of the 3D sets that is overly expensive, requires glasses, or induces headaches.

It's not like there aren't a ton of options out there.

I recently bought a 60" Panasonic plasma to replace my 5 year old 42" LCD. 3D added nothing to the price. The glasses are extremely lightweight and comfortable. And Tron Legacy (paid $25 for the version with DVD, Blu-Ray, 3D Blu-Ray and "digital copy") looks almost as good at home in 3D as it did in the theater.

Maybe you should try it before you claim you (or anyone else) isn't interested.

I request a weekend in Havana with Phil Silvers!
