Questions on '3d' imaging

Hello, it's my understanding that any device can display a "passive 3d" image and that the new top of the line projectors are using twin projection systems in one to create a better "passive 3d" image.

One of the things I'm wondering is will a '3d' projector display a better '3d' image of a passive variety compared to an equal '2d' projector model.

Also is the '3d' projector able to take a passive signal and use it's active technology and glasses to produce a more life like '3d'.

Furthermore is a '3d' projector able to up convert any image to '3d' be it passive or active from 2d or '3d passive' source?(I don't think so but just covering all the bases)

Thank you for your time and input.

Oh I must be then as I was under the impression that there were multiple ways to create a '3d' image one by rendering two images together be it a left and right "eye" view and then producing different wavelengths for each eye (ie horizontal and verticle or red and green images ect) then the viewer would wear specialized glasses in the wavelength of the respective views.

The other way (active) that I know of uses completely separate images one at a time which alternate (refresh) at generally 120hz while the active glasses are synced with the image frequency and limit viewing through one eye or the other at the same frequency (thus called shutter glasses)

But I may be mistaken as I am not big into "3d" I prefer reality view/vision lol.

Sorry about this forum didn't realize there was a 3d specific one.

Well they can't use the same signal unless they are rendered with two images as in the first explanation depicting different wavelengths and the active player then reads this information and separates the images were as the passive system would not. I have always just assumed they were generated and rendered differently such that some times you buy a '3d' movie and it will come with passive lenses in the box to be played with any device even an old crt TV and sometimes you buy a DVD which does not include glasses and requires a '3d' device with an active system.

See you may be right (and ofcourse I'm not trying to argue or disagree with you) all so called '3d' movies may just use the wavelength format (if you will) and some DVDs just might not come with the glasses (in which case the reader or display device may interpret this signal and convert it into an active signal for the shutter system) however this would still negate the need for "3d" ready hardware as we have never needed this equipment in the past (ofcourse that fact wouldn't prevent companies from inventing and marketing new technology but that's another discussion).

I have heard and agree that a passive system is much more comfortable and natural to watch not to mention less straining (although you cannot tell I still believe there to be a minor effect). So I cannot see the reason for an active system unless there were different rendering technologies; cinemas still use by majority a standard 1920X1080 LCD projector and use the passive wavelength format.

I hope you fallow...I do allot of analog and digital video editing and can myself create '3d' footage in the wavelength format (anamorphic I believe it is called but I may be mistaken) although I have never (nor my clients) had the need to work with or create this type of footage before.
