[osg-users] Spatial View SVI autosteroscopic display support.

I am currently looking at the feasibility of adding support for SVI 
autostereoscopic display in OSG.
Does anyone know anything about this?
So far, I have been looking at an SDK that provides an OpenGL based API and 
examples for driving the display.
I have also been looking at the different ways OSG implements stereo modes 
with a view to seeing where might be the best place to perform the interlace 
function required to support the SVI display.
I noticed that the WOWVX support is done by creating two slave cameras that 
render to textures, then combining the textures and wowvx headers using a 
pixel shader. So, at first, that seemed a good pattern to try and follow, 
but on reflection it's difficult for me to see how to use the SVI API in 
this way (even though internally I suspect something similar is going on).
I seem to be floundering a bit., so I wondered if I can trouble anyone on 
the list to take a quick look at the attached OpenGL example code from the 
SVILaceOGL SDK and make any suggestions about how and where the best place 
to try and use the API from within OSG (or from an OSG application).
Of course, if I'm successful with the integration, I'll be happy to share 
the result with the OSG community. ;-)
