Celestia in REAL 3D view..

[kinderino]

Hello to all, and especially mains actors of Celestia..

Not sure if someone tell about this here or experience it but i find that it it easy to do 3D view with the Celestia 1.3 multiview option using that crossing eyes technique on 2 photos that i use to play with my own pictures.. I will just show some examples here. I am sure some of you will try it..

How to do it?. Choose an object, track it, split verticaly. And on the left image, mouse over the object, hold and move the mouse just a little bit (or more) to the left.. Et voila!.. Have fun!..

P.S. may be this 3D option can be program and added as an easy option in next version of Celestia..

Nice day.. Jean-Pierre

ok, i understand, but whats the point? i cant separate my ayes and look ate both pictues at the same time, one with each eye.

kinderino,

Thanks!

ElPelado,

Yes, you can (if you have two working eyes, anyhow)

1) make Celestia's window small enough so that the centers of the pictures are separated by the same distance as between your pupils, or slightly less. Then relax your eyes or look past the pictures to something in the distance. The left image becomes centered in the view of your left eye and the right image centered in your right eye. the two pictures will slowly merge and you'll see a third picture between them that has depth.

2) cross your eyes so that your left eye is looking at the right picture and the right eye is looking at the left picture. Some people find this easier than #1, but the pictures also have to be reversed.

There are many Web sites with 3D pictures that work this way, including one with 3D pictures of Nebulae. See http://nzphoto.tripod.com/3dastro/

AAAAGGHH! My head! It looks very cool, though. Perhaps I would enjoy it more without the aneurysm. Here's an idea: Now that Celestia has built-in support for multiple views, perhaps it wouldn't be too difficult to do the binocular vision thing in-code. For instance, the nVidia-based ASUS card I have came with these funky 3D glasses that weigh a ton. I think the trick is just to switch views every other frame to match the flickering of the glasses. Just a thought...

ok, in that page i could see the 3d pics, but i coundt see yours

abiogenesis,

I don't have a card like that, but I thought it was all done in the hardware and graphics drivers using the z-buffer information, with nothing special done in the higher level software. Am I wrong?

I think I remember seeing posts here by someone who was using Celestia with such a configuration. Yup: just a few "minor" problems.

selden,

That's how it's done independent of the app. Any 3D program with z-buffer info can be stereoscoped by the drivers. I was thinking that an application-specific implementation, if that's even possible, would give better results.

Now that I think about it, though, it's really not that important a feature. The glasses are uncomfortable as all get-out, anyway.

That's remember me a project I was working on a few months ago.

After having seen some pics seen in the nasa site, using the blue-red system (as know as an anaglyph), I began to dream for a celestia where, using a special glasses, I could immerse into a real 3D world.

So I used the moon texture to try this new way of Celestia browsing, and the result is :

You need this kind of weird glasses, of course. Red lens on left, blue lens on right, and the sensations are good enough

The great problem :
-> It works only with b/w pictures !!!

If anyone is interested in making an anaglyph, the best program I found was :

Feel you free to let me know what you think about the moon anaglyph.

I think most video card support 3D stereo these days, check NVidia's page on the subject for example.

3D glasses cost arround $20, and they work really well if your monitor supports high V frequencies. Sadly there's no support for Linux yet so I haven't been able to test it with Celestia, but it should work.

[ElPelado]

i have also found a program similar to celestia that has te option of turning the view to stereo, with gren-red or blu-red glases, or to do like the pics in this post.
the name is StarStrider.

[GuySoft]

beat me to it, i was just loging in the fourm to sugest adding this kind of 3d feature, and by the way, they are called stereograms.

kinderino, Thanks for your post. I'm a big fan of stereo views and I did'nt even think of doing it that way with Celestia. It works great. Though I prefer parallel eyes views than crossed eyes views.
For those who can't see the 3D effect, you have to persevere in trying. It worths it. You can also use a stereoscope, that way it is very easy to see the effect.
With Celestia and the new window split feature, if you set 2 different POV (point of view), you can see the 3D effect while the time is running. Very interesting to see the Mutual events that way.

I prefer the cross eyed method. I'm not sure, but I think you HAVE to use the cross eyed method when you look at the pictures posted in this topic because of the way each side is aligned. It helps alot if you sit farther back from your monitor, about 5-6 feet (1.5-2.0 meters or something). That way you don't have to cross your eyes much at all, it is very comfortable, and you can easily focus on the image. You don't have to change the size of the rendering window on your monitor to fit the width of your eyes this way, although the picture is still reduced in size due to your position farther from the screen.

Thanks for pointing this out!

One of the great things about Multiview is that it can be used for 3d.

We have been experimenting with 3-d using both analyglyph(red/blue) and
shutter glasses (see http://learn.arc.nasa.gov/exp/) and check out Viasim. The 3-d space station app is particularly good. I think it would be relatively easy to make a 3-D celestia - as mentioned before, shuttler glasses are now about $30. the red blue analglph are 50 cents.
Also once drivers are written for 3-d glasses, they can be used for 3-d projection systems as well. THe 3-d shutter glasses typically use odd even scan lines and fast refresh rates, but a projector with a lcd crystal shutter can do the same thing.

Hi all..

It is been some times.. I was like busy elsewhere... So i thanks you all for any replies about using or making 3D view with Celestia.. It was very interesting to read some of you..

Nice day! J.P.
