I did not use OSG for this test, but QUAD BUFFER stereo works on all NVIDIA
Quadro cards. The problem was caused by the (USB) emitter for the shutter
glasses. Currently it is not supported under Linux (NVIDIA statement).
Hope this helps.

Nickel ;-)

It is working very well with 2 projection design projectors and 2 linear
polarisation filters...
But it is quite hard to configure correctly the projectors alignment and the
special screen is fragile.
Of course the price is also quite prohibitive.

As far as I've experiment, it is much more comfortable to use a DepthQ
projector. The glasses are more expensive and more heavy to wear, but the
config is simplistic and the results are good.

Cheers,
Pierre.

Thanks a lot for this info...
Can you tell us more ?

Was OSG QUAD_BUFFER stereo working ?
The monitor doesn't have to be use with 3DVISION I guess...

I have had some very nice results with DepthQ projector and CRT monitor, but
I've never tried any LCD...

Yes, it's not passive but active stereo in this case...
The last news I've read  on nvidia's forum was talking about an Linux
version possibly available at the end of this year, so I don't think it is
already available.
If someone has some more recent/precise infos about Linux 3DVision...

Re: [osg-users] Stereoscopy with Linearly polarized glasses

2009-08-17 Thread Pierre BOURDIN 
Hi Alexandre,
to have a stereo rendering, you need a to have 2 images on the device
separated by the polarised barrier... This gives you plenty of possible
configurations, like 1 projector and a filter wheel or 2 projectors with 2
filters etc...
There is now some "new" passive stereo monitor mostly using circular
polarisation, but I haven't tested any of them with OSG, maybe someone has
made some experiment ?

You can have a look at this site to have more details:
http://www.inition.co.uk/inition/product.php?URL_=product_stereovis_jvc&SubCatID_=3
This one is available with linear polarisation:
http://www.inition.co.uk/inition/product.php?URL_=product_stereovis_miracube_g170s&SubCatID_=3


Concerning the film Ice Age 3, it is not using the same method. It is based
on Infitec stereo, a colour multiplexing method.
There was a discussion about it:
http://forum.openscenegraph.org/viewtopic.php?p=15140#15140

If you want to see it near Marseille, they are using this infitec system at
the Centre de Réalité Virtuelle de la Méditerranée de la Faculté des
Sciences du sport de Luminy:

Hi Maxim,

Isn't it possible to set passive stereo with polarized glasses on a single
classic LCD screen ?
Or the only way to do this is to plug 2 projector (aligned) on 2 output from
a graphic card ?
My goal is to know if a standard OSG application running on a computer
desktop (with a GUI) can be set to produce passive stereo with polarized
glasses.

[osg-users] Stereoscopy with Linearly polarized glasses

2009-08-17 Thread Alexandre Amalric 
Hi osg-users,

I would like if it's possible to set the osg viewer display setting the way
we can use linearly polarized glasses (like Ice Age 3 in 3D)?

For info from wikipedia :

*To present a stereoscopic motion picture, two images are projected
superimposed onto the same screen through
**orthogonal*
* **polarizing* * filters. It is
best to use a silver screen so that polarization is preserved. The
projectors can receive their outputs from a computer with a dual-head
graphics card. The viewer wears low-cost eyeglasses which also contain a
pair of orthogonal polarizing filters. As each filter only passes light
which is similarly polarized and blocks the orthogonally polarized light,
each eye only sees one of the images, and the effect is achieved. Linearly
polarized glasses require the viewer to keep his head level, as tilting of
the viewing filters will cause the images of the left and right channels to
bleed over to the opposite channel – therefore, viewers learn very quickly
not to tilt their heads. In addition, since no head tracking is involved,
several people can view the stereocopic images at the same time*
**

Kind regards,
