I was looking at some Imax 3-d DVD's on line. I know you need the polarized glasses, but as far as the projecter goes, will it work or are there certain projecters for that type of 3-d ?

You typically need a special projector. Here's one that I've heard of:

A 3D projector somehow has to get two different images to your two eyes. This one works with a shutter built into glasses which alternates between the two eyes, and which is synchronized with the projector.

The other kind of 3D projector has two images which pass through perpendicular polarizers that match ones on the glasses. Dual projectors work nicely for this. :)

Really cheap 3D can be achieved with red and green filter glasses. This is only good for black and white content, and will ultimately make your head ache -- or was it the really cheesy 3D movies made in the early '50s that did that, independent of 3D? :D

The other kind of 3D projector has two images which pass through perpendicular polarizers that match ones on the glasses. Dual projectors work nicely for this.
Or one DLP Digital Cinema projector and a Real-D system (http://www.reald.com/). :D

There have been a few "add-ons" for PCs and TVs that allow field sequential material to be viewed as 3-d in the home; but, many of those have problems with timing the displayed image and L/R eye signal for the glasses.

Here is a link (http://www.vrealities.com/imax.html) to one that I just found using Google. Go to the bottom of the page.

Good luck!

A while back there was a broadcast episode of Medium that was in 3d. It worked (Kind of) on my DLP projector with free glasses that were given out in the TV guide for that week. The glasses had two different color lenses.

Found these instructions on a google search of Imax 3D DVD

"How to get 3D-DVD's working on a TV-set or projector with TV-shutterglasses

System requirements:

- A DVD-player set to standard 60Hz-NTSC output mode! If you got a progressive-player turn off progressive!
- Some TV-shutterglasses
- A standard TV-set or CRT-projector which supports NTSC in 60 Hz!!! Non-NTSC-TV-sets, european 100 Hz TV's, certain digital TV's, HDTV's, Plasma, LCD, LCoS, DLP and other fancy stuff will usually cause severe problems!
- Some european 50Hz-PAL TV's which usually don't support NTSC may do so via the Scart-RGB input.
- Some standard DLP- and LCD-projectors do work via the video-input, as long as they don't do de-interlacing and as long as the time-gap between video-input and projection isn't too large. Just try it!
- Alternatively you could use a 3D-video compatible HMD, a special 3D-projector or a dual-projector-setup with demultiplexer, polarizer-filters, polarizer-glasses and a special non-depolarizing silver-screen. "

Interesting article on toms hardware website a while back, with the author walking thru his successful attempt to set up a 3d gaming/movie viewing room using an inexpensive DLP projector. Pretty good stuff.

There is a third method using the shutter glasses called "field sequential." I have a VirtualFx system with wireless glasses hooked up to my little old business class Sharp XR-1S DLP projector and it works perfectly. As in BIG's quote above, you have to be able to disply an interlaced signal at 60Hz. That limits you to coax, composite or S-vid, but to me the picture still looks amazing.

There are scenes in SOS Planet (originally an IMAX presentation) that still make me jump and I KNOW they are comming!

All good input. I will research more, but keep your thoughts coming.

Thanks everyone
