3D Glasses by QtanJ on 01-30-2006 at 05:44 PM

I wondered if I wanted to buy some 3D glasses. I think this is a bit expensive, but it is much better than this cheap one?  I know it's good that it doesn't require that you look at your monitor, but is it a better feeling using the expensive one rather than the cheap one? If the expensive one is much better I'll rather wait than buying a cheap one which uses color filter technology.

I don't think it would be a good idea to buy them at all to be honest, a complete and utter waste of money. The novelty will wear off, and I doubt there's much compatible software for it anyways.

Bah, but it will most probably be the more expensive ones that are better.

(I think it would be a big mistake).

Probably wouldn't be too good for your eyesight either.

I wouldn't think they would improve your Gaming/PC Exprience a lot at all. I'd stick with Stiggy's glasses is I were you.


RE: 3D Glasses by QtanJ on 01-30-2006 at 06:09 PM

You're probably right, maybe the only "good" use of the expensive one is when i'm travelling alone over bigger distances. I've heard rumors of good software to the cheap one. The cheap one comes with software that makes many 2D games and 2D movies 3D in a good way. Far Cry and Half Life 2 is two of the games i've heard became much better in 3D.

[Ironically]When do I need a good eyesight?[/Ironically]

Before I decide anyway I'll try making my own to find out if it's worth it(which I doubt)

You can not make your own 3D glasses as the ones you want to buy...

There are 2 major categories of 3D simulation glasses:

1) The ones shown by Stigmata here (and the only types you could make yourself, if you have the absolute correct color filters!)

EDIT: since Stigmata deleted his post:

Kids! Make your own

These will only work with special made up pictures. You also can't see much color (if not none at all) with these as they actually work by filtering out de reds and the greens or the blues. The glasses are not universal; Each (own made) glasses are only useable for a specific set of colors, depending on exactly what colorfilter you've used.


2) Hardware 3D glasses which actually consist of 2 tiny displays.

These work by showing 2 slightly different pictures on each display (thus left and right). Viewing colors with these is possible.

3) see Fluffy_Lobster's addition

---

All methods require very specialized drivers and very specially adapted software. 3D glasses simply will not work if the game/program does not support them!

To make your own 3D glasses type 1, you need the exact color filters, any other even slithly different filter will cause the 3D effect to totally fail. For this kind of use, programs and pictures in magazines etc use a specific color to draw the pictures and many magazines, pictures, etc use different ones. So, the chance that the 3D glasses you got from a magazine, will not work with another picture from another magazine, is extremely high.

---------------------

Follow the advise posted before: do not waste money on such things, unless you swim in money and have absolutely no clue what to do with it. If useable at all, they (type 2) will only be usefull for 1 specific program/game....

---------------------

EDIT @ Traxor: I fail to see the joke in a question like that in the way it was asked and being asked in TechTalk though...
RE: 3D Glasses by user27089 on 01-30-2006 at 06:56 PM

Cookie, it was a joke.


RE: 3D Glasses by fluffy_lobster on 01-30-2006 at 08:32 PM

Erm, actually cookie there are three :P

In places like imaxes, where 3d glasses are probably the most commonplace, the 3d glasses have "lenses" made out of pieces of polarising plastic, with their polarities arranged perpendicularly. The projection then consists of two images made up of light of perpendicular polarity, resulting in each eye seeing only one of the images, though both being in full colour.

RE: 3D Glasses by QtanJ on 01-30-2006 at 08:33 PM

I tought about making the filter glasses to find out if it were better experience than with only a ordinary monitor. The cost of the 3D filter glasses is very small(if I make it myself) and if I use my printer and a transparent sheet I'm pretty sure I'll get the right color, at least if I define the color myself.

If I use one program to make the 3d more realistic then it'll work on every game(that's supported)

I'm going to use Nvidia 3D Stereo.

For bf1942 on a scale from 1 to 5 the stereo value rating for is 1, the compability is 3 so I guess I can try bf1942 in more realistic 3D.

The only joke I meant as a joke was in the [Ironically] tag.

That will not be a color filter...

A color filter filters out wavelengths of color. What you will have when printing color on a transparent sheet of paper is nothing more than a colored (untransparant) box, this is not a color filter at all.

A color filter lets light with another wavelength thru (eg: a red color filter will filter out (aka reflect) the red, but more importantly for this: it will let other wavelengths pass).

What your sheet will do instead is blocking/absorbing all wavelengths (except for the red which is reflected), because you use inkt (or toner, whatever). Inkt, or any other stuff they suggest (like crayons or coloring, etc) are not color filters and as such will not work decently or will even not work at all.

Fluffy, yep correct, thanks, I've added it

(though, I bet there are some more 3D type of glasses though, but all work on some same principle as listed in the 2 3 types I guess)

what about these: http://www.chromatek.com/ ?
or are they the same as already posted? i dunno cuz i dunno how they work...

yay: 1000 posts :o):o):o)

It's the same, but different...

Instead of filtering on specific colors, they "filter" based on chroma-key and the particular defraction of each color wavelength instead of simply filtering out colors (though, color is also closely related to chroma-key). Principle is the same though: both eyes see a slightly different picture... Hence: the same, but different :p

Such 3D images are composed of actually 2 images and each image is draw in either red or green (or whatever other two opposite colors; often blue is used instead of green).

The two images (each in their own color) are almost the same but slithly shifted compared to eachother. The more the shift, the more the shifted object is viewed deeper/closer.

The glasses filter out one set of colors. So your left eye will only see one colored image (eg: the red one) and the right eye will only see the other colored image (eg: the green one).

And because they were shifted, compared to eachother, your brain will interpret this as depth. The color you'll see in the final image (in your brain) is a mixture of the two colors on paper (and depends on what eye is the strongest; each human has a strong eye and a weak eye).

(the electronical hardware versions of this work more or less on the same principle)
RE: 3D Glasses by QtanJ on 01-30-2006 at 09:11 PM

Of course , now I get it.  Didn't think about a transparent color isn't necessarily a filter itself, but just a transparent color(you know it's possible to print transparent colors?)

Have to buy some special color filter sheets then.

Actually, you understand it wrongly though.

It is impossible to print a transparant color.

This is because you use inkt, this is not a translucent material; the inkt drop will cover the area entirly and will not let any light thru. The "transparent effect" (note the quotes) comes only from the fact that not everything in the area is covered by a inkt drop. Blown up a printed red square looks like:
X    X    X    X    X
   X    X    X    X    X
X    X    X    X    X
   X    X    X    X    X
(where X is a miniscul red inkt droplet. The rest is just the unprinted paper (or transparant sheet). The inkt also lays on top of the paper, it isn't the paper itself).

Hence this red square will not filter out the red color. Any color will simply pass where there is no inkt drop and will simply be blocked where there is a inkt drop. The red color you see when you look at the red square comes from the light that falls on the red ink drop and which is reflected (hence the color of the inkt is red as only red is reflected and the rest is absorbed).

A filter is something entirly different, it is a true transparant sheet which is entirly made out of a certain color. There are no dots of inkt on there; the entire sheet is the same transparant color:
XXXXXXXXXXX
XXXXXXXXXXX
XXXXXXXXXXX
XXXXXXXXXXX
XXXXXXXXXXX

Hence you will never be able to print color filters.

Or find some colored plastic sheet to experiment with (eg: green bottles, red plastic cover of some toy, etc). It will not be a thru calibrated color filter also, but will come very close. Of course, you'll need to adjust your paintings to the colors of the plastic.

PS: the dotted pattern produced with printing will also defract and defusse the light; the light shined thru will be blurry, while if it is passed thru a true filter, it does not diffuse, it stays equaly sharp.
RE: 3D Glasses by QtanJ on 01-30-2006 at 09:44 PM

You automaticly assumed I've got a ink printer. You've got that right but if I didn't tell what sort of printer I had I could have used a laser printer. The next thing to say is to assume I can't get the transparent effect(without quotes since it's the real transparent effect i'm talking about) with the laser printer either. Then the only thing to do is to buy light filters or to stop thinking about making 3D glasses(hopefully I stop think about the 3D glasses)

EDIT: and as a last tip: you can get professional true filters for free in the form of "swatch books" (small handy booklets containing all available filters from a company; though small, they are big enough to use as filter for such 3d glasses). If interested I'll PM you the instructions to order such swatch book. I wont post this in public, as this is actually meant for professional (theater/tv-)technicians and if too many people order this "just for fun", they might stop this service.
