WOWvx / 3d displays


I’ve just seen a Philips TV with WOWvx capabilities, and although it seems nice, i think similar effect can be created withing OF and a filter they have on the TV.

Anyone has any idea what kind of filters they use, because having a 3d animation with depth information is kinda easy, if we can find the correct filter, we can replicate the technique with projectors, etc.…

Yeah, how DO those screens work? They are definitely using some sort of lenticular system. This-page says they are using “fixed lenticular” and then “9 different views”. Somewhere else I saw Philips using the term “slanting lenticular”, and they seem to have some new patented technology here.

But it seems like they’re not really showing true stereoscopic material, just 2d with an additional depth map and then somehow generate a “3d” view.

At least in theory you could buy lenticular sheets (for example, at and glue them to your screen, and then write software to render 3d to that setup. Did anybody here try that?

I think it might be tricky to get it right though, you’d probably need to get a lenticular sheet that fits your particular dot pitch (or perhaps it is easier finding a screen that fits your sheet…) and also align it properly. You want pixel perfect here. But definitely worth a try!

Ungaro, how do you figure “replicating the technique with projectors”? While 3d projecting is possible, it’s not something you do with lenticular sheets, right?

PS - The Firefox spellchecker insists that it’s called “testicular screen”. :slight_smile:

i used to work in a company that had a few f those screens.
i kinda think they are lame! the 3d they produce is not very realistic. they display 9 perspectives of the image in the lenticular surface, and you see the correct one depending on the angle you are looking at the tv. as you move you kinda get a sense of depth in the image. the problem is when you stand between 2 angles you see a mixed image of 2 perspectives.
but it would still be cool to make a home made version of this but wouldn’t it require to somehow project 9 different images on a lenticular surface?
