I just came home from a 3 week vacation to america and i was at disneyland.

I saw a 3d video where you get those 3d glasses and there is a video playing and it looks like it comes out of the screen.

When i took off the glasses i noticed some things which may be correct:

- There is a small color noise on the 3d objects in the video.
- There are 2 shapes of each shape going to each their side.
- The closer they are the further the 2 shapes go from eachother.
- The faster the shapes move the 2 shapes go further from eachother.
- The shapes seems to be partly transarent.

So after the video i came up with an idea!
I could try to make my own 3d video
So i took 2 pairs of 3d glasses with me home.

I got this type of glasses:

Not these:

Anybody know what i must do to make the 3d effect?

I have Sony Vegas 7.0

I think this is produced through a red ofset, I sore an example of this on the forum somewhere once, but it came with a warning that it ran slow.

You can't. Those glasses work using polarised light so a simple red green offset won't work. You'd need very expensive specialised equipment.

1. You can already get 3D games for PC + PS2, aswell as 3D DVD's, (no Secalist Equipment Required, just a pair of 3D Spec's)
2. Do a search ont his forum under Anaglyph

I undrestand that there are 3D Systems which use 2 monitors in a headset/glasses which show the same thing, but from a slightley different angle, this is a much better and more realistic, this requires specalist equipment, last time i looked you could get these for about £200 a pair, they could also tell if you where rotating your head, and could respond appropriatley.

The Red/Blue Glasses option is doable in DarkBasic, but may be slow, and i beleave DirectX does support advanced 3D for many games with the correct equipment, but i dont know if this has been passed through to DarkBasic.

yes, but if you look at his post, he is NOT using red/green glasses. THey are, as jrowe said, the ones that use polarised light, so just making the red/green bit on the film won't work.

Ok i think i got it.

But the glasses i use wont work, and i dont know how they work either, all i know is they worked somehow

Here is some info:

http://www.wikihow.com/Make-3%E2%88%92D-Videos

I made a test with 3ds max.

I made a small scene.

Setup 2 cameras like eyes pointing to the middle of the scene.

They are close to eachother just like human eyes.

Then i made a box and animated it to bounce around the scene and then speed towards the cameras.

Then i recorded both cameras with animation and put them in sony vegas.

Then i added an overlay to both of them, one with cyan and one with red.

I think it works but i got to get the other glasses first.


[EDIT]

Maybe it actually would be possible to create a DBP game in 3d.
Just take 2 offsets from the camera and add the overlay and draw them together.
All you need is the glasses

I'm sure you're right - that's more or less how I would do it. If I had the glasses I would have tried it by now.

I had a go at the 3d effect.

If this is 3d I will make a tutorial on how to do it.

This is possible, DavidT did it years ago using 2 camera's rendering just like your 3DS Max scene, then I think he used full screen sprites with the diffuse set to red and blue and alpha to 50, so they blend together.

I hate 3D films and movies. They look like crap and the glasses make them worse than without the glasses. A LONG time ago I remember watching "Spy Kids 3D" and just thought it was HORRIBLE.

Personally, playing a game that tries to emulate that would turn me away from it instantly, and I'd get a refund on it (Provided I payed for it).

Cheers,

You obviously haven't seen a "real-d" 3d movie. They're flawless, and totally awesome. I went and saw Beowulf, it made the whole thing way more immersive and interesting.


Hurray for teh logd!

Beowulf is great but i have never watched it in 3d

And the 3d effect, red and cyan glasses: I think that the reason you make the 2 views colored red and cyan is because each side of the glasses only accepts one color and therefore it looks like it is 3d because without the glasses your eyes would read all the colors

I will see if i can get one of those red blue glasses and make a test

That is the original right?
If so, then i dont think it would work but i could give it a try tough.
You would probably need 2 different views or else we dont have depth of the objects.

I did. I changed the image, so it was red and then I made is so it was blue(on another layer) So I had 3 layers all together. Then Multiplied each one, then I the blue slightly to the left, and the red slightly to the right.

Yeh, i get what you mean, it will probably create a small 3d effect but it would kind of look "fake" i think.

if they are just the same image but moved over a bit, it'll look flat. The closer an object is, the farther apart the blue and red is from eachother.

kindof on topic if you have nvidia graphics hardware from the fx (5000) 6000 or 7000 series then you can get stereoscopic gaming using the 91.31 driver and it's stereo driver addon which you can find on nvidia's website with a quick search.

this driver supports all sorts of modes of creating the stereo effect, personally i have the lcd shutter-glasses and a crt for it but if all you want is anaglyph then the newest stereo addon with the newest drivers will also work for you even with the new nvidia hardware (8000 9000 series anyway) but the new release is designed for the zalman 3d monitor. there is another driver that will work in anaglyph if you have ati hardware, can't remember if it was the iz3d one or the zalman one.

stereo (3D) gaming is cool but some people find it just a gimmick, some people swear by it though. (shutter-glasses work with dlp projectors too)

just thought you might be interested

Thanks mm0zct, i will look at that

I have started a small 3d test, i have not yet started the 3d drawing since i need some help on how to do it.

I was thinking making a function that gets 2 images and adds a transparent overlay of their colors (left:red,right:cyan) and then setting one of the images to be 50% transparent and drawing that on top and the other below it.

Those 2 things i dont know how to achieve.
Some help on doing it would be good.

Btw, this is what i have so far:

My brother just found some 3d glasses from an old game called Flåklypa 3d:



It was lying in our house and work on other youtube videos.

Now i just need to make the 3d effect in the test game.

I need some help on that, above i have written what i need help with.

So you haven't tried set cameras to stereoscopic yet? Shame on you, download U7.0 Beta, it's there I promise you.

Of course, you may have to wait until the next newsletter to work out how to implement it.

If you still don't believe me, check the file location of this image...



I can be such a tease sometimes

Ok, i will look at that after i have posted my new 3d test i made with 3ds max!

Its a meteor flying around in the screen, its 3d but i should change the colors more.

[EDIT]
Ok, i upgraded and now i will try to set it up... If it works

You are sooo right :S
I cant get what stereoscopic mode is, says that image doesnt exist when i set it above 0


Btw, the image you included looks 3d enough to me

[EDIT3]

That demo was awesome
It felt like i was gonna be hit by those objects!

I put some particles (from the cloth and particles plugin) into the scene, it's a much better demonstration of the 3D effect when things are moving.
