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: http://www.realite-virtuelle.univmed.fr/index.php?option=com_content&view=article&id=3&Itemid=40&lang=fr Cheers, Pierre. 2009/8/17 Alexandre Amalric <alex.pix...@gmail.com> > 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. > 2009/8/17 Maxim Gammer <maxgam...@gmail.com> > > Hi >> >> >> http://www.openscenegraph.org/projects/osg/wiki/Support/UserGuides/StereoSettings >> >> and 2 monitor\proector () >> >> :) >> >> >> 2009/8/17 Alexandre Amalric <alex.pix...@gmail.com>: >> > 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.
