Hi, I need help with stereoscopic implementation! stereoscopic implementation
  1 / 2    
Hi, I need help with the following:
For the Architects market I would to build a stereoscopic 3D station that will include the following:
1. Two polarized projectors with passive glasses.
2. One polarized white wall screen.
3. One PC with Microsoft XP.
4. One Nvidia GeForce card with two outputs.
5. The Architects 3D software can export VRML (X3D) files.

My question is how the Nvidia card will get the files and “generate” the two pictures for the two projectors?

When I am using the 3D files (VRML) with cortona viewer I can see the 3D application on the screen, my question is: when I use the Nvidia card, who will generate the two “shifted” images for the two projectors?

Hi

If You have some kind of program to generate a 3D world (from a VRML) like what a game does.
Say normally the driver shows on 1 projector what the world looks like 100 frames per second.
When You activate 3D it calculates what the world looks like from 2 slightly different viewpoints 50 frames per second and display one each on each projector.
If You don't have a program like that then just take 2 slightly different screenshot of the generated world and make a 3D picture. There is a built in 3D picture slideshow in the 3D driver. This works in real life also /photo.gif' class='bbc_emoticon' alt=':photo:' />

Hi Freke1,
Thank you for your reply. This is my problem, I have the VRML output but don't know how to generate the 2 out pouts for the projectors.
I was told that Nvidia can do it automatically with their new 3D board, is it right?
Thanks,
Reuven

Yes, though this Nvidia cards have been able to do many years.
If You have the hardware (projectors) set up and installed the 3D driver then:
1. Install Cortona3D (http://www.parallelgraphics.com/products/cortona/)
2. Copy a VRML file to the harddisk
3. Open a browser
4. type: "file:///C:/my_vrml_files/house.wrl" (or similar) instead of "http://www.......com" (the VRML picture will be displayed)
5. rightclick picture and choose Fullscreen - More - and choose the resolution You have chosen in the 3D driver (from nVidia) (the VRML picture goes to fullscreen)
6. Ctrl-T to activate the 3D (with polarized 3D glasses - adjust it! and fly around the object in 3D)

Hello Freke1,
After running the VRML file with Cortona, I need that the Nvidia card will have two outputs, one for each projector, for passive 3D glasses.
Is it right?
Thanks,

Yes, I would think so - never tried it myself.

Do you know where can I find a "recipe" for this application?

Yes, there's a thread in MTBS3D's forum about 3D with 2 projectors:

Hello Freke1,
I read the article and it was very impressive.
I still missing the information about the software! what kind of software do I need to be able to present interactive architect 3D design?
Thank You,

Hi
You only need a 3D driver like this one: [url="http://www.iz3d.com/t-dcdriver.aspx"]http://www.iz3d.com/t-dcdriver.aspx[/url]
Just download it, install it, hit the Hot key and the image on the projectorscreen goes from 2D to 3D basicly.

Hello Freke1,
I still don't understand how the driver will produce [u]2 outputs[/u] for the [u]2 projectors[/u]?
I guess that for "supported" games the driver (Nvidia or other) will build 2 pictures which are not taken from 2 different points exactly (2.5"), but (probably) mathematically calculated.
Since I provide a VRML file "someone" need to generate the 2 pictures (2.5'' apart) for the 2 projectors.
For my application, do I need 2 viewers that will generate 2 separated pictures from 2 points (2.5" distance)?
Thank You.

Hi and happy newyear

The "someone" is the 3D driver I think and "supported" only means "hey it works!" :lol: .
The thing that's surprising is that the driver can change 1 view into 2 views of an application/game by activating 3D on the keyboard.
I don't know how but it can, so You don't need 2 applications/viewers/pictures. The driver somehow interacts with the application it is not just some software that afterwards displays the view the application/game has calculated.
It's kind of magic :magic: but You get used to it.
Here's wriggle of my computer showing a game in 3D:

Hi and happy newyear

I understand.
So it is not like 2 cameras from 2 points!
Do you feel some kind of distortions?
