3d - which glasses?

I just picked up a pair of 3d glasses from a local movie theater.
They don't seem to be tinted red and blue, but appear to have clear lenses....I tried changing a bunch of settings in the vegas project, but nothing appears to give a 3d effect.....how should i go about this?
thank you.

Those are probably polarized lenses that require a special projection system which cannot be duplicated by your PC monitor. You should stick to red/blue glasses.

As John said, those glasses are polarized lenses at 180-degrees from each other. (Look at someone else wearing the same type glasses, and you can only see one eye). You see 3D because there are two projectors. One for the left eye, and one for the right. Each has a polarizing filter in front of it so that when you wear the glasses, each eye sees the image intended for it.

Wired Magazine did an article recently on how you can make your own 3D home theater out of two LCD monitors:

Another one: look in a mirror with the 3d polarized glasses. Move your head a little. Shut your right eye, then your left. Pretty cool huh!?

You want some wierd 3D glasses, try 3D fireworks glasses.

Those glasses also will not work on a modern 3D tv. The new TV's require what's called SHUTTER glasses.

They're actually lcd lenses that can be switched dark or clear by an infra red timing signal from the tv. The lenses alternate open or closed at high speed relative to the picture timing of tv's left/right image flashing

Actually I need to correct myself here.

Apparently VIZYO [check spelling] has come up with a PASSIVE 3D video system on their new 65" display. Reviews clearly state that it is not quite as good as the active shutter system... mainly because it will only do 3D at a max of 540p... but those glasses *MAY* work with this tv.

"I just picked up a pair of 3d glasses from a local movie theater"
With or without the operator's consent?

Building the polarisers into the screen (http://news.yahoo.com/s/yblog_technews/20110106/tc_yblog_technews/eyes-on-with-vizios-passive-3-d-tv-displayspolarized TV[/link]) will degrade 2D viewing. So yes, your new glasses may be useful with a Vizio set.
